I have a new domain controller which is set up as the main active directory server in a domain which previously was just a workgroup, oneof the machines has server 2000 (standalone) rather then 2000 pro on it.

I have logged all the pro machines on ok but everytime I try to attatched the machine with server 2000 onto my domain I get the following error message :-

The following error occured attempting to join to domain "direct"
The credentials supplied conflict with an exisiting set of credentials


what does this mean ? I have not added the computers name in the active directory users/computers ...

help !

You'll get this error if you have opened any shares on the Domain controller before running DCPROMO.

Commented:
make sure the administrator password is the exact same on both servers before joining new domain

If you have drives mapped onto the DC, unmap them before adding the machine onto the domain.
The drives mapped (or indeed any shres open) will be in the name of the logged on user, and when you try to add the machine to the domain using the domain\Administrator user, it conflicts with the shared user.
