Error occured Accessing Data Source Error ID 5566

By peter.stilgoe









If you are getting the error when opening an Infopath Form ‘Error occured Accessing Data Source Error ID 5566′ its normally an authentication issue with the datasource the form is trying to retrieve data from. This normally occurs in ‘cross domain’ environments. The fix for me was to disable the ‘Authentication Loopback’ check:

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\Control\Lsa

3. Right-click Lsa, point to New, and then click DWORD Value.

4. Type DisableLoopbackCheck, and then press ENTER.

5. Right-click DisableLoopbackCheck, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Exit Registry Editor.

8. Restart the computer.

    we are having a similar error, however the reg settings have already been implemented. We have recently configured SSL cert on the site and are attempting to access forms via https when 5566 error occurs.

    Any thoughts ?

    thanks,

    Mike
