Cannot promote a 2003 Server in a 2000 domain

Posted on 2007-11-26

I have a 2000 server with AD, DNS and DHCP that I am trying to decommission, I have a new Server 2003 enterprise edition ready to rock and roll. However, whenever I goto dcpromo it, it throws up an error almost immediately stating that "Multiple connections to a server or shared resource by the same user, etc.." and I cannot promote it.

I have rebooted both machines and the 2003 server is set to use the 2000 server for DNS.

have you ran the domainprep and forestprep to prepare AD for a 2003 dc?

if so issue net use from the command prompt and disconnect anything that shows up.

Did you configure a map network drive for your administrator account recently from this server that you are attempting to promote to DC? If so, can you disconnect that network drive and try again?

There are no mapped drives.. I will try forestprep and domainprep, I've gotten different errors along the lines of you have not prepped the domain etc..etc.. I thought.

I have rebooted both the servers and there are no connections between the two boxes

Register this server in your DNS server and ensure it has A record?
the TC/IP properties of this server, its DNS should point to your DNS server
from your current AD, try pinging this member server by hostname and ensure you get a response

Log onto the machine as local administrator and then try again - you will need to run Adprep on the 2000 DC from the 2003 CD to update the schema as well. You need to run both
Adprep /forestprep   and
Adprep /domainprep

Adprep is in the i386 folder of the 2003 CD. If the new Windows 2003 server is the ‘R2’ version then you need to run Adprep  from CD2 of the R2 disks on the existing Domain controller. Adprep is in the \CMPNENTS\R2\ folder on CD2

I have run both adprep /forestprep and /domainprep on the 2000 server but still cannot promote the 2k3 server with the same error.

The operation failed because:

Managing the network session with \\servername.domainname.local 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."

run netdiag and dcdiag from your other dc and see if you have any errors, seems like a service may not be running like file replication service or tcp/ip netbios helper
