We have a network with 2x Windows 2003 machines in the office, one with exchange, one is a DC. We store files on the DC that clients need to access. We have all XP Clients.
Recently, a very odd thing started happening--clients can logon to the domain fine, and they can can access the DC by going to run \\dcname\share without any problems. However, if you go into my network places and browse the domain, every computer is there (workstation and the other server) EXCEPT the DC. I have no idea why, but want to get this fixed.
I have noticed that if users go to Network Places and click on "Search Active Directory" under network tasks, and searches for computers, that the DC appears in the list.
Also, some clients when browsing the domain in this manner see nothing (no computers) intermittently, but this problem appears to be fixed when the user logs in and out and / or the DC is rebooted. This may or may not be related.
Looking at client event logs, there are only a few things that may or may not be related:
In the system log, there is an LSASRV Error EventID
The Security System could not establish a secured connection with the server ldap/TBISA01.firstname.lastname@example.org. No authentication protocol was available.
I looked on EventID and it stated this might be related to DNS credential settings on DHCP, so I checked and changed this but it still isn't helping.
