I have 2 XP machines on a LAN + several NT and 2k PC's. One of the 2 Servers required rebuilding which are both NT 4.0 servers. Both XP PC’s connected ok to bother servers before the rebuild.! The original PDC died and had to promote the BDC to PDC. The original PDC is now back on but left as the BDC. Either XP box can no further than seeing the BDC server name. They will not get any further. I get the following error: "\\Server\Download is not accessible. You might not have permission to use this network resource. Contact Administrator of this server to find out if you have access permissions. The network path was not found." As above you can see I did manage to create a network place before access stopped. To add to the confusion, I did have a connection for about 30 minutes, and had one of the XP boxes connected to Exchange. All the NT and 2k boxes connect without a problem. Not even a reboot in most cases! Note. I’m not very familiar with XP! I've added the XP box again into the Domain but didn't help. I can ping the server. The login script does run. I can get out via the Router to the Net. I also tried changing the servers over from PDC to BDC etc!! My question. Is this XP or something todo with the new NT 4.0 SPa build ? and how do I fix it quick. Big thanx to any help with this?

From the XP machine, can you PING boith the BDC by IP address as well as by it's name? If you can't do it via name, then you've got a DNS issue. Also, on the XP machine, open a command ptompt and type "ipconfig /flushdns". This will clean out the cached DNS info on that box. If that doesn't work, try removing the XP machine from the domain, then rename it to something else, and join the domain with that new name (I've seen some strange things get cached and not cleared unless the machine is actually renamed). If that doesn't help, start a new post...
