Characteristics of different RAID configs

By peter.stilgoe









RAID 0 (Stripe set without parity)

•No Fault Tolerance
•Best read and write performance
•I/O per disk calculation: (reads + writes) / number of disks

RAID 1 (Mirrored Volume)

•Fault Tolerance: 1 Disk may fail
•Performance: Good read, Acceptable write
•I/O per disk calculation: [(Reads + (2 x Writes)] / 2

RAID 5 (Stripe set with parity)

•Fault Tolerance: One disk may fail
•Performance: Excellent read, fairly poor write
•I/O per disk calculation: [(Reads + (4 x Writes)] / Number of Disks

RAID 10 (Stripe of Mirrors)

•Fault Tolerance: Half of the disks may fail (but not both disks in any mirrored pair)
•Performance: Excellent read and write
•I/O per disk calculation: [(Reads + (2 x Writes)] / Number of Disks

RAMMap – How Windows manages memory, analyze application memory usage, how RAM is being allocated

By peter.stilgoe









Have you ever wondered exactly how Windows is assigning physical memory, how much file data is cached in RAM, or how much RAM is used by the kernel and device drivers? RAMMap makes answering those questions easy. RAMMap is an advanced physical memory usage analysis utility for Windows Vista and higher. It presents usage information in different ways on its several different tabs:

Use Counts: usage summary by type and paging list
Processes: process working set sizes
Priority Summary: prioritized standby list sizes
Physical Pages: per-page use for all physical memory
Physical Ranges: physical memory addresses
File Summary: file data in RAM by file
File Details: individual physical pages by file

Use RAMMap to gain understanding of the way Windows manages memory, to analyze application memory usage, or to answer specific questions about how RAM is being allocated. RAMMap’s refresh feature enables you to update the display and it includes support for saving and loading memory snapshots.

Sharepoint MOSS 2007 Web Front End Server Event ID 6398 6482 7076

By peter.stilgoe









Article ID : 946517
Last Review : August 7, 2008
Revision : 4.0

SYMPTOMS

Consider the following scenario. You have a process that has more than one thread. Additionally, the process uses the Internet Information Services (IIS) Active Directory Service Interfaces (ADSI) provider to access IIS. Two threads access IIS at the same time. In this scenario, you may be unable to manage IIS by using Server Manager.

When this problem occurs, you must restart IIS, or you must restart the process that uses the IIS ADSI provider.

This problem is likely to occur for the SharePoint Timer service (OWSTimer.exe) in Microsoft Office SharePoint Server 2007. When this problem occurs for the SharePoint Timer service, you may experience the following symptoms:

• In SharePoint Server 2007, tasks that are scheduled do not run.

• On the SharePoint Web front-end server, you see repeated errors in the Application log in Event Viewer. These errors usually include one of the following three events:

• Event ID 6398
• Event ID 6482
• Event ID 7076

For example, you may see an error message that resembles the following:
Event Type: Error
Event Source: Windows SharePoint Services 3
Event Category: (964)
Event ID: 6398
Date: 11/7/2007
Time: 5:45:38
PM User: N/A
Computer: 44MOSSAGRUK
Description:
The Execute method of job definition Microsoft.Office.Server.Administration.ApplicationServerAdministrationServiceJob
(ID 02b5e3f2-21e3-4552-bf1d-6e152749458a) threw an exception. More information is included below.

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

• When you try to manage IIS by using Server Manager, you receive a blank page, or you receive the following error message:
the path specified cannot be used at this time

How do I determine which version of IIS / ASP I’m running?

By peter.stilgoe









If you are running Windows Server 2003, you are running IIS 6.0 / ASP 3.0 (though some people like to call this ASP 4.0).

If you are running Windows XP, you are running IIS 5.1 / ASP 3.0.

If you are running Windows 2000, you are running IIS 5.0 / ASP 3.0.

SBS 2003 SP2 Broadcom NIC’s & slow network !

By peter.stilgoe









Using the above & network performance is nothing short of shocking ?!? Broadcom TOE nics ? (all TOE enabled nics will prob need these edits)

It looks like that due to the fact that SP2 includes Scalable networking pack, the Checksum offloading stuff and Receive Side Scaling might be causing some issues and the symptoms you will see is slow file copies, problems accessing web sites and DHCP issues where your workstations won’t pick up an IP address, Secure NAT and VPN issues especially with Premium boxes. To disable this do the following:

To disable checksum offloading:

From the registry you can do:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Click Edit, point to New, and then click DWORD Value.

Type DisableTaskOffload as the entry name, and then press ENTER.

Right-click DisableTaskOffload, and then click Modify.

In the Value data box, type a value of 1 , and then click OK.

Disable RSS (Receive side scaling)

http://support.microsoft.com/kb/912222/en-us

1. Click Start, click Run, type regedit , and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. On the Edit menu, point to New, click DWORD Value, and then type EnableRSS .
4. Double-click EnableRSS, type 0 , and then click OK.

SBS 2003 SP2 Broadcom Event ID 1053 1054 RPC Errors !!

By peter.stilgoe









After four frustrating days I have finally managed solve the “SBS 2003 SP2 Broadcom Event ID 1053 1054 RPC Error” problem !

OK basically we bought a new Dell server with Broadcom Extreme II NIC’s & SBS 2003 premium. Went through the basic setup & install all pretty straightforward, join the domain OK, DNS all working OK etc etc.

Install ISA all still working OK, the I install SP2 for SBS2003 & now client cannot join the domain & exisiting members are not getting group policy updates applied, in the event log they are getting ID 1053 & 1054 RPC server unavailable, after days of troubleshooting it appears the problem lied with the SP2 update & the broadcom NIC’s.

If you are getting this problem its due to RSS (Receive Side Scaling) on the NIC which you need to disable in the registry:

Use the steps in KB 927695 to disable Receive Side Scaling (RSS) by adding a DWORD registry key value for

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip
\Parameters\EnableRSS

and setting it to 0.

(Like the KB article says, usual caveats about having a backup, etc apply before making any registry changes).

You will also need to edit the advanced properties of your NIC to disable the RSS at driver level.

Once you have done both of these, reboot your server & the “SBS 2003 SP2 Broadcom Event ID 1053 1054 RPC Error” problem will be solved ! (well it was in my case)

Cannot open firewall on SBS 2003 ipnat.sys

By peter.stilgoe









By default, the firewall is disabled on SBS SP1 because the SBS uses the
Basic Firewall in RRAS to protect the LAN and the SBS itself. Also, since
SBS host many services, if you enable the Windows firewall on SBS, it will
result in many problems. When you enable the option, then a Windows
Firewall bounce box will occur which tell that you can not enable the
firewall.

If you are using SBS Premium, ISA server is used to protect the security
of your network.

Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

By peter.stilgoe









This error arises when the System registry hive is either deleted or corrupt. System registry hive contains configuration information necessary for the system to boot.

The first thing to try is to run chkdsk command from the Recovery Console and then reboot the system.

If chkdsk does not solve the problem, then the System file should be restored from backups. There are two places to look for the backups, one is the System Restore folder and the other is \Windows\Repair folder.

From the Recovery Console, navigate to the folder \System Volume Information of the root drive, using the command:

cd “C:\System Volume Information”

Here, locate and navigate to the folder whose name begins with _restore using the command:

cd _resto~1

This folder contains many subfolders which have names of the form RPxxx, where xxx is a number indicating the restore point. Locate an RPxxx folder which has the highest number as its suffix (highest xxx) using the command dir command. Then navigate into that folder using the command:

cd RPxxx (don’t forget to replace xxx with the corresponding number!)

Now, there will be a folder named snapshot. Navigate to this folder using the command:

cd snapshot

There should be a file named _REGISTRY_MACHINE_SYSTEM, copy this file to the \Windows\System32\Config folder with the name System using the command:

copy _REGISTRY_MACHINE_SYSTEM C:\Windows\System32\Config\System

Then reboot the system. This method works only when the System Restore feature of Windows XP is enabled.

While installing Windows, the setup backs up the System registry hive in Repair folder. If the System Restore feature is turned off, then this backup can be used to restore the System hive. From the Recovery Console, navigate to folder \Windows\Repair, using the command:

cd C:\Windows\Repair

and then copy the System file to its original location using the command:

copy System C:\Windows\System32\Config\System

and reboot the system.

The disadvantage of this method is that, since the backup is created during the installation of Windows, by restoring this backup all the system configuration and driver installations made after it will be lost.

I am connected to the VPN but cannot access the Internet.

By peter.stilgoe









This occurs when “Use default gateway on remote network” in the TCP/IP settings is checked.

To check for this in Windows XP:

Click Start -> Control Panel

Click on the Network and Internet Connections icon and then click “Network Connections”. If your Control Panel is in classic view, simply double click the “Network Connections” icon.

Right click on the new VPN connection and select Properties

Select the “Networking” tab

Verify that Internet Protocol (TCP/IP) is highlighted

Click on the Properties button

Within the Internet Protocol (TCP/IP) properties window, click on the “Advanced…” button.

Within the Advanced TCP/IP Settings window, REMOVE the check mark next to Use default gateway on remote network

Click “OK” to close all open windows

However this is not recommended as it results in something known as ‘Split tunneling’ effectively this turns your VPN client into a bridge between the outside world & your internal network!

Microsoft FileMon – monitors and displays file system activity on a system in real-time

By peter.stilgoe









FileMon monitors and displays file system activity on a system in real-time. Its advanced capabilities make it a powerful tool for exploring the way Windows works, seeing how applications use the files and DLLs, or tracking down problems in system or application file configurations. Filemon’s timestamping feature will show you precisely when every open, read, write or delete, happens, and its status column tells you the outcome. FileMon is so easy to use that you’ll be an expert within minutes. It begins monitoring when you start it, and its output window can be saved to a file for off-line viewing. It has full search capability, and if you find that you’re getting information overload, simply set up one or more filters.

FileMon works on NT 4.0, Windows 2000, Windows XP, Windows XP and Windows Server 2003 64-bit Edition, Windows 2003 Server, Windows 95, Windows 98 and Windows ME.

Installation and Use

Simply run FileMon (filemon.exe). You must have administrator privilege to run FileMon. When FileMon is started for the first time it will monitor all local hard drives. Menus, hot-keys, or toolbar buttons can be used to clear the window, select and deselect monitored volumes including network volumes (Windows NT/2K/XP), save the monitored data to a file, and to filter and search output.

If you’ve specified filters then FileMon will ask you to confirm filters used from the last session each time you start it. To start FileMon without it prompting you specify the /q switch on the command line. When FileMon starts it automatically captures file system activity. To start it with capture disabled use the /o switch on the command-line.

As events are printed to the output, they are tagged with a sequence number. If Filemon’s internal buffers are overflowed during extremely heavy activity, this will be reflected with gaps in the sequence number.

Each time you exit FileMon it remembers the filters you’ve configured, position of the window and the widths of the output columns.

How to reset your TCP/IP ~ Winsock stack in Windows XP

By peter.stilgoe









Most Internet connectivity problems arise out of corrupt Winsock settings.

To reset, at the command prompt (Start > Run, type cmd, click ok)
type: netsh winsock reset

This command resets the Winsock catalog to the default configuration. This can be useful if a malformed LSP is installed that results in loss of network connectivity. While use of this command can restore network connectivity, it should be used with care because any previously-installed LSPs will need to be re-installed.

To show a list of Winsock LSP’s:

netsh winsock show catalog

Note that resetting the Winsock using netsh winsock reset catalog command in SP2 removes all the third-party LSPs and restores Winsock to factory default setting. Existing programs that uses their own LSPs, need to be reinstalled again. IE. Google Desktop Search.

Users cannot send e-mail messages from a Blackberry mobile device through Exchange server

By peter.stilgoe









Active Directory users can receive email but not send through their Blackberry device

Granting the Full Mailbox Access permission implicitly granted permission to send as the mailbox owner. This meant that another account that has the Full Mailbox Access permission could send e-mail messages that appeared as if they were sent by the mailbox owner.

Many Microsoft Exchange customers have requested that Send As permission be separated from the Full Mailbox Access permission for the following two reasons:

• To deter e-mail spoofing.
• To make sure that e-mail messages that are sent by a delegate can always be clearly distinguished from e-mail messages that are sent by the actual mailbox owner.

All new versions of the Exchange Information Store will now explicitly require the Send As permission in order to send e-mail messages as the mailbox owner.

To override this to allow the user to send email from the Blackberry device follow the steps below:

Task 1:

Make sure that the BlackBerry Enterprise Server is running as a separate, unique account
Make sure that the BlackBerry Enterprise Server is running as a separate account that is specifically created for administrative tasks. By default, this account is called “BESAdmin.”

If you have a separate account for administering the BlackBerry Enterprise Server, go to task 2.

If you do not have a separate account, create a separate account. Then, use this account to perform administrative tasks. For instructions about how to do this, visit one of the following BlackBerry Web sites, as appropriate for the version of BlackBerry Enterprise Server that you are running.

If you are running BlackBerry Enterprise Server 4.0 or BlackBerry Enterprise Server 4.1, visit the following BlackBerry Web site:
http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=9174704&sliceId=&dialogID=11024244&stateId=1 0 11020632 (http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=9174704&sliceId=&dialogID=11024244&stateId=1 0 11020632)

If you are running BlackBerry Enterprise Server 3.6, visit the following BlackBerry Web site:
http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB04334&sliceId=SAL_Public&dialogID=11016727&stateId=1 0 11020358 (http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB04334&sliceId=SAL_Public&dialogID=11016727&stateId=1 0 11020358)

Task 2:

Make sure that the BlackBerry Enterprise Server service account has the correct permissions
Verify that the BlackBerry Enterprise Server service account has the correct permissions.

Note If the account is within a domain, make sure that the account is a member of only the Domain Users group. On a domain controller, the account should be member of the Built-in Administrators group. 1. On the BlackBerry Enterprise Server, follow these steps: a. Make sure that the account is a member of the Local Administrators Group.
b. Assign “Log on Locally” and “Log on as a Service” permissions to the account.

2. Grant Exchange View-Only Administrator permissions at the administrative group level. To do this, follow these steps:

a. In Exchange System Manager, right-click the first Exchange Server administrative group name, and then click Delegate Control.
b. Notice that the BlackBerry Enterprise Server service account is listed as having the role of Exchange View-Only Administrator.

3. Grant “Send As,” “Receive As,” and “Administer Information Store” permissions at the server level for each Exchange Server server. To do this, follow these steps:

a. In Exchange System Manager, right-click the first Exchange Server administrative group name, and then expand the Servers group.
b. Right-click an Exchange Server server, click Properties, and then click Security.
c. In the top pane, select the BlackBerry Enterprise Server service account. In the bottom pane, make sure that the “Send As,” “Receive As,” and “Administer Information Store” permissions are set to Allow.
d. Repeat steps 3b and 3c for each Exchange Server server.

4. Grant “Send As,” “Receive As,” and “Administer Information Store” permissions to the mailbox store. To do this, follow these steps:

a. In Exchange System Manager, right-click the first Exchange administrative group name, and then expand the Servers group.
b. Expand the first mailbox store group, right-click each mailbox store, click Properties, and then click Security.
c. In the top pane, select the BlackBerry Enterprise Server service account. In the bottom pane, make sure that the “Send As,” “Receive As,” and “Administer Information Store” permissions are set to Allow.
d. Repeat steps 4b and 4c for each mailbox store on each Exchange Server server.

5. In the Active Directory Users and Computers snap-in, follow these steps: a. Right-click the user for which you want to add permissions, and then click Properties.
b. On the Security tab, add the BlackBerry Enterprise Server service account, and then click to select the Send As check box.

If you are not running Exchange Server 2003, see task 3.

Task 3:

Clear the cache on the BlackBerry Enterprise Server

To clear the permissions cache in the Information Store, restart the Blackberry-related services and restart the Microsoft Exchange Information store. After you restart the Information Store, you must restart the RIM Blackberry-related services to give the “BESAdmin” account the newly-added Send As permission on the Exchange Information Store.

If you are an administrator in the domain (ie. a MS protected account) you need to also do the following:

(Note: Microsoft do not recommend doing the following but their best practise isn’t very usable for many blackberry / exchange users who are also admins for their Active Directory.)

Run the following command on a DC:

dsacls “cn=AdminSDHolder,cn=System,dc=domain,dc=com” /G “domain.com\BESAdmin:CA;Send As”

Replacing Domain with YOUR domain.

The dsacls tool is not a standard util but you can download it from here:

http://www.microsoft.com/downloads/thankyou.aspx?familyId=6ec50b78-8be1-4e81-b3be-4e7ac4f0912d&displayLang=en

Also if you are having trouble executing the above command it is probably because you are specifiying the LDAP info incorrectly, you can download a free tool http://www.ldapadministrator.com which will let you browse to the AdminSDHolder object. Then by looking at the tool bar you will see the exact path needed to use in the dsacls command example above.

All should work fine now!
