I HAVE A 2003 SERVER RUNNING EXCHANGE 2003 ON A POWEREDGE 600SC AND HAVE STARTED MOVING IT TO A POWEREDGE 2550 WITH RAID5. What has been done so far is. dcpromo the new 2003 box. installed exchange 2003. moved mail boxes over. moved all 5 fsmo roles and cheacked the new box to be a global catalog. I have did a sync on exchange public folders. I can shut down the old 2003 box and everything looks like it is working fine untill you try and have a client pc join the domain. (states it cannot find a domain controller.) Or if a user in AD trys to log onto a box they have never logged on to before fails. Also if you reboot the new 2003 server with the old one off the exchange system attendant fails to load and therefore the information store does not load. but I have been able to start them manually. I seem to think I have a AD problem of some sort. So in short both servers are needed to run for everything to work fine. But I need to pull the 600sc out of production.

maybe you forgot to change the DNS settings on your DHCP server to point to the new server or you have a global catalog problem. when i was doing migration between two pc's i had to demote the old server from the domain to transfer all the changes to the new one. i would recomend you to make an image of both servers (in case something goes wrong) then demote the old server

I agree, sounds like a DNS issue.

Check your host records IP address values for your DC in your Forward DNS lookup zone.
Check your pointer records IP address value for your DC in your Reverse DNS lookup zone.
Also check DHCP assignments for Primary DNS server to clients.

run nslookup from a command prompt
What are the results?
Silly question but did you check to make sure DNS service is installed on the new server??

I installed dns on the new server. i ran nslookup on the new server and got "can't find server name for address non-existent domain default server: unknown address: On the new 2003 server under forward lookup zone i have i have 2 pointers to the new server, 1 of them is labeled (same as parent folder) and the other is labeled the name of the server which is called exchange. i also have 2 name server records, one for the old server and one for the new. i did nslookup on the old server and get the same results. also i do not do any dhcp assigning going on. should i uninstall dns on the new server and reinstall? also what would be a good  image software that would do a image of a scsi drive running 2003 that is not offthe chart expensive.                                              
on the new DNS server did you configure the TCP/IP settings on the network adapters to point at the local machine, rather than on to the internet or the old DC???

The dns settings in the network adapter points to itself (that being the new dns server) with the alternate pointing to the internet.
