Good morning, i've recently runned into a weird problem i wasn't able to track down yet. Yesterday morning a number of users reported that their domain PCs would hang loading the Operating system just before the logon screen would appear. they're all stuck on Applying computer settings. The moment i unplug the network cable the PC will finish its startup procedure and show the logon screen. The network is made of a single forest/single domain, all DCs are Win2000 Server SP4. 4 sites across 2 Mb fast links (no evidence of traffic overload). Each site has 2 Dcs including the one (and only) site where the problem has been reported. DCs seem to perform fine. They have been rebooted, checked event logs, checked with netdiag and dcdiag. replication is working fine. None of the 2 DCs in the affected site hold FSMo roles. All other DCs on the network are working fine. There have been no modifications on group policies, memeberships so forth. Sysvol and netlogon shares are accessible. One of the 2 DCs in the site is the AD DNS server for the site and shows no problem (can resolve queries, can register records, SRV records are present and appear correct). on the client side: this has been reported on random machines attached to different network hardware. They're a mix of WinXP and 2000 machines, though the problem seems to affect mainly win2000. EventID 3034 is logged (checked most comments from eventid.net). client time looks synched with the DCs time. Once the machine is started through the unplugging cable tweak it's able to resolve from AD DNS. All network settings have been checked twice both for server and client and appear correct. Hosts file is clean. Attempted to remove one machine from the domain, and it would reboot fine. however, it was a hard task to join it again to the domain (reported RPC errors, network name no more valid...finally i could join it to the domain but it started showing the issue again...). The issue has been reported on 15-20 domain machines out of about 200. Please, please..help! I just can't get out of it (the problem...the office). thank you!
