Adding a 2nd Domain Controller (Win 2003)

I am trying to add a 2nd Domain Controller (active directory) to my local network for disaster recovery.

I run dcpromo, go through the steps ==> select "Additional domain controller for an existing domain" ==> enter the network credentials for a domain user with Domain Admin permissions ==> Enter domain name (pre populated) ==> Enter new passwords ==> Go

I get the following error:
The operation failed because: Managing  the network session with \\COMPNAME.DOMAIN.COM failed. "Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

I replaced my domain name with "COMPNAME.DOMAIN.COM"  above. The network user I used does not have any network shares. It was a user I just created on the DC just for this purpose.

Any ideas?

Check if TCP/IP NetBIOS Helper and File Replication services are started first.

Logon to the server as local administrator and repeat the dcpromo procedure and before hit Finish execute the following from a command prompt:

net use * /delete

r_panos, Local Admin? You want me to login locally, not to the domain?
Yes, but check the services first

Thank you. "File Replication" was not started.

Quick question: Once this is setup, do I have to input my DHCP reservations on both servers manually or is their a mirror available?
