  [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. ] System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail) +781 System.DirectoryServices.DirectoryEntry.Bind() +44 System.DirectoryServices.DirectoryEntry.get_AdsObject() +42 System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne) +98 DanielPS.Roles.ADRoleProvider.ADSearch(String ConnectionString, String filter, String field, String scopeQuery) +464 [ProviderException: Unable to query Active Directory.] DanielPS.Roles.ADRoleProvider.ADSearch(String ConnectionString, String filter, String field, String scopeQuery) +1545 DanielPS.Roles.ADRoleProvider.ADSearch(String ConnectionString, String filter, String field) +98 DanielPS.Roles.ADRoleProvider.GetUsersInRole(String rolename) +611 DanielPS.Roles.ADRoleProvider.IsUserInRole(String username, String rolename) +95 System.Web.Security.Roles.IsUserInRole(String username, String roleName) +803 Site.Page_Init(Object sender, EventArgs e) in C:\inetpub\portal\excon\CO-NC\Site.Master.vb:53 System.Web.UI.Control.InitRecursive(Control namingContainer) +133 System.Web.UI.Control.InitRecursive(Control namingContainer) +421 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1970

  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.
