Xp Pro Wont Join An Nt4 Domain

[aromes]

I have a Windows NT4 PDC and am trying to have a Windows xp pro

workstation joining the domain controlled by my win nt4 pdc.

On the win nt4 pdc, I did add in "user manager for domains"

the user/password account I use on the win xp workstation.

Still on the windows NT4 PDC, in SERVER MANAGER, I did add successfully

the windows XP computer as a Windows NT workstation (only option

available for my win xp workstation).

Then from the win xp computer, I went to System properties,

then "Computer name" tab, and I clicked on the CHANGE button.

Under "Member of", I checked DOMAIN and I did mention

the domain name. Windows XP confirmed that I was part of the

domain with the pop up "Welcome to domain xyz".

Then win xp rebooted, but when logging on to the domain from the

win xp computer, I get error "Windows cannot connect to the domain,

either because the controller is down ... (which is not the case, because

the other workstations have access to the domain and both the win xp

computer and the windows NT 4 pdc are seeing each other via network

neighborhood/or windows explorer) ... or because your computer account was not found

(On the win Nt4 pdc, in "Server Manager", the win xp computer is there....but if

I double click on it, it says that the trust relationship between the win nt4 pdc and

the win xp workstation failed....even if I succesfully selected the win xp pc from there and chose

the option JOIN DOMAIN)....

I am really out of options and would appreciate your help.

Thanks

Have you checked to make sure that Netbios is enabled? If not, enable it.

I would also check to make sure that NTLM authentication is enabled. Check to see if Local or Domain security policies do not disable this method.

Good luck.
