Here is a good one. We just recently upgraded our domain to AD 2k3 native mode with only 2 DCs from AD 2000 in mixed mode with 3 NT 4 BDCs and 2 AD 2000 DCs. We have about 1200 client machines running mostly XP and 2k some 9.x machines but not many, Dell and HP mostly. I don't know if it is related to the domain upgrade but since then we have had 3 Dell Laptops running win 2k have this very strange problem. One at a time we'll get calls where they say that their network drives aren't mapping during logon, and when we go to look at their machine we try to logon and we get "The domain is not available." It seems that in the network configuration it'll have the Netbios name of the domain listed on these machines so what we do to fix it is, remove the machine from the domain, and then readd it using the FQDN of the domain. This seems to allow us to atleast logon to the domain successfully. Anyone ever seen anything like this happen before, or have any ideas if this might be related to the domain upgrade we just did? Maybe it is due to the fact that we used to have 5 DCs and now we only have 2? But 2 should be good for 1200 clients don't you think?
