I have a problem that is very puzzeling and I am hoping someone will be able to help me out. First, the description.
I have to remove a old Windows 2003 DC from my site and I am replacing it with a new Windows 2008 DC. This is a seven site network, all using the same domain. The old 2003 DC held all the master/emulation roles and was also a certificate server (We don't need it and it was setup by the old admin for Exchange webmail purposes, using 3rd party cert now). I transferred all roles to the new 2008 DC without any problems and I then uninstalled the CA services from the Windows 2003 DC. This is where the problem began.
When the users would go to access the newly mapped drives (mapped to the new 2008 DC) their workstations would stall/freeze up. The problem could be resolved by rebooting the new Windows 2008 DC. After a couple of days I decided to demote the old Windows 2003 DC and make it a member server, which I did without issue. This solved the problem of the user workstations freezing up for about 5 days. This morning however the problem occurred again.
I have checked the event logs on workstations and the server, but nothing at all. The only clue I was able to find, and on one workstations at that was a LSASRV 40961 SPNEGO error. This error corresponded to the time the problem occurred, but like I said it was only on one workstation.
I have verified that the new DC hold all the roles needed, I have made sure all traces of the CA server have been removed from AD. I am not sure what is causing this problem. Any ideas please would be greatly appreciated.
