I have a network with 2 servers, an existing Windows 2000 server and a brand
new Windows 2003 server. Our objective is to change the server names so that
the new server gets the name of the existing server.

My plan was to demote the old server and then rename it. I would then
promote it back. I could then demote the new server, rename it and promot it
back. I have already moved all of the roles to the new server in
anticipation of the demotion of the old server.

I cannot demote the old server because it cannot login to the new server. If
I try to access shared directors on the new server from the old server, none
of the credentials work. I can login to the new server with other domain
computers in the local network.

The new server is running ISA. The old server Proxy. There are no rules that
apply to the servers only. I'm at a loss to explain why this is happening.
Any ideas?
