I have a small network of about 30 computers. We recently installed a new router (Sonicwall) and transferred the task of DHCP to it instead of our Windows 2000 server. Now our users are getting long login times where Windows 7 just sits on the welcome screen for a while. Eventviewer throws the following errors:
The processing of Group Policy failed. Windows could not resolve the user name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
This computer was not able to set up a secure session with a domain controller in domain WESTMINSTERCO due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.
I am not very knowledgeable of troubleshooting client-server problems. Can anyone shed light on this?
