I have a client who has a server running Windows Server 2000 and several client machines running XP. They recently tried to login to one of their XP machines and are not able to access the server (the system worked fine the day before). It looks like they are not connecting to the network as the XP machine that's not working is getting a 169.X.X.X IP and the rest are 192.X.X.X. I also looked at the network connection properties and there were 0 packets received. It seems like the usual TCP/IP settings are correct. They have also been having another problem on this machine which may be related: They say that when they login to this particular machine, they aren't able to change most settings because they get an error about not having proper permission. When the same user logs into a different machine, they don't have any problems.
Since I don't know much about Windows server software, I was wondering:
1. It looks like the user accounts are controlled by the server. Am I correct that if the network had a physical problem (bad NIC card, etc) they wouldn't even be able to login to the XP machine?
2. I had them log in using other accounts and they continue to have the same problem. Is there some setting on the server or client that would cause this behavior? I looked around in the Active Directory settings and found the settings for the different machines and they all appear to be the same.
Thanks for your help...
