[ProviderException: Unable to query Active Directory.]

Nov 27, 2012 05:06 AM|lordplazikovbj5|LINK

This problem occurs since last week. Before that the application worked fine, there hasn't been a change to the AD and the code for 2months. Only an .net update on the webserver.

Line 53: Dim waar As String = Roles.IsUserInRole(userkort, group)
Line 54: Session("QA") = waar

[COMException (0x80072020): An operations error occurred.

Hi lordplazikovbj5

It hardly troubleshot just from the error information, you should give more detailed information about our project.

The problem was in the IIS. On the authentication part: WIN AUTH => providers => the two providers Negotiate and NTLM where switched by an windows update ...

After changing this the problem was solved.

But thanks for helping me.
