An old set up of SBS 2003 Standard was completley bunged up, corrupt AD, IIS, Sharepoint, everything was totally corrupt and broken in every way, so a reinstall was needed. The same domain name, same user names, same shared folders, everything set up to be the same as the previous install. The only hardware that's changed is the hard drives in the box and the RAM.
Since the user names, and domain name is the same the users old computers and profiles connect to the new domain and authenticate fine, and can access all domain resources as though nothing has changed. However every time a user tries to log on, they have to try several times because each attempt gives them an error trying to find the domain controller.
After several attempts, the number varies from computer to computer (with two computers being able to get in the first try), they log on successfully and everything works as it should.
My initial thought was that this was a network connectivity issue, so I started pinging from the server to each of the workstations, and there have been 0 dropped packets, and no reply times over 3ms so I'm pretty much ruling that out. Also the server doesn't seem to have any issues with anything else on the LAN or the Internet.
I'm wondering if this could be a result of the computers not being added to Active Directory. Or if it's because of something else.
The server is a fully patched, fully updated with SBS SP1, Server 2003 SP1, SharePoint SP1 and all the rest of everything. All workstations are fully updated XP SP2 boxes.
