User is not authenticating by Windows 2003 domain controller, please assist

User is not authenticating by Windows 2003 domain controller.

We have two DCs, one W2003, next one is W2000

We upgrade our domain to Win 2003, but still we kept the W2000, will demote later on.

Right now some users are authenticating by W2000 DC.

How can I Force user authentication to 2003 domain controller?

Thanks,

Set the DNS of each user computers to the find the Win 2003 first.

The DNS will not help - the DC that a client chooses to authenticate with depends of the site information and the SRV record properties. Assuming that all these DCs are in the same site you will need to manually change the SRV record priority for the LDAP service

Open the  DNS Console
Expand Forward Lookup Zone
Expand YourDomain.name
Expamd _MSDCS > _TCP

Locate the LDAP and KERBEROS entries for the DC that tou want to be used and change the priority to 0

Locate the LDAP and KERBEROS entries for the other DC(s) that tou want to be used and change the priority to 1

I have to add that it is not normally a problem which DC a client authenticates to - why do you feel the need to change it ?
