Tried changing the name of the XP Pro box and rebooted for it to take effect. Although I still had the mapped network drives (didn't disconnect them) and printer I wanted to see if it worked.
Unfortunately not. Still getting the same error, and still cannot connect to the server using \\servername but need to use \\serverinternalip
From another XP Pro box I can connect to the server using \\servername , so it seems that something is not right on my reinstalled XP laptop, but I can't figure out what it might be. Shouldn't be the firewall as it has a Zone specified for the 10.0.0.1 to 10.0.0.255 allowing all types of traffic.
Again, any suggestions?
EDIT: Well, it works...Tweaked the firewall on the XP machine, stopped and restarted it and now I can connect to the SME Server using \\servername .. Adding the XP Pro machine to the domain however still does not work, but I'll disconnect the shared drives and printer again, do a reboor of the XP box and will give it another go.
