Symptoms

Assume that you have a computer that is running Windows 7 or Windows Server 2008 R2 in a Windows Server 2008 R2-based domain environment. When there are no domain controllers available, the computer's startup and logon processes may be slower than expected.Note The time that is required to start and log on to the computer increases when one or more of the following conditions are true:

  • The computer does not have cached IP addresses of the domain controller.

  • The computer does not have access to a working DNS server.

  • The DNS server that is available to the computer cannot resolve SRV records for the domain controller.

When domain controllers are unavailable, the computer tries four times to locate a domain controller, and an event is logged for each try. The event that is logged during the first try resembles the following:The events that are logged during the second, third, and fourth attempts resemble the following:

Cause

This issue occurs because the GetUserNameEx function tries to locate a domain controller three times after the first try fails. Then, the Group Policy engine has to retrieve the distinguished name of the policy target by calling the GetUserNameEx function. However, if a domain controller is not available, it is unnecessary for the function to try repeatedly to locate a domain controller.

Resolution

This hotfix is also available at Microsoft Update Catalog.
