A few vague recollections from the deep recesses of the old’ gray matter….
1.  Make sure there are no hosts or services references on the DC server to Vantage (or mfgsys61) – this can confuse things in DNS tables.
2. If you made changes on the DC for #1 do a flush DNS on the new Vantage server
3. Double check at the Services file has the right ports on the new Vantage server
4. Manually check the DNS settings on both servers and verify no obsolete references to the DC server
5. Was everything uninstalled on the DC server?
6. Worst case – REGEDIT on the DC and look for  references to Vantage, Progress, mfgsys61, probuild and delete them
I ran into many of the things above when we switched servers once. Mostly it did not keep things from running but when they eventually ran it was very very slow. Starting up Vantage would take 10-15 minutes to get a login screen. The network was seriously confused due to DNS and server name conflicts with the Services ports.
Hope this helps,

Subject: [Vantage] Vantage 6.10 question
I am moving 6.10 off the domain controller to a 2003 Server Standard machine.
Progress installed nicely. The service pack installed nicely.
Vantage installed nicely. Progress explorer shows the database running.
I try to start Pa610542P.exe and nothing happens. I tried run as administrator.
I brought up a CMD window, navigated to the folder and it still won't run.
Any ideas?
Thanks
