Situation: NT4 PDC with exchange 5.5 installed, no BDC. Installed w2k3 standard server, ran ADMT and transferred users. Ran ADC and connected users to there exchange e-mail. Tried exchange 2k3 in 5.5 organisation and got as far as selecting 5.5 server and came up with error 'could not bind to server, server did not respond'
Researched the issue, found info but none of the solutions worked, I heard there was a hotfix but couldn't find the link.
Anyway I'm against the clock so I stop DHCP server on NT4, and start my new scope from 2k3, joined the 50 users to the network successfully, they still get there e-mail from the connectors and all there home drives data crossed over etc, ran scripts for mapped drives.
Problem: NT4 is the only machine that doesn't appear in network places, I can ping it from 2k3, it resolves as I created A record in my DNS. NT4 uses WINS, my new domain uses DNS, and WINs is supported. From the PDC I can connect to the new domain, two way trusts exist in both directions, and users still get there e-mail. Up until when I switched to the new network its is refusing to connect.
My solution: I want to demote the NT4 to BDC, but will this effect the exchange 5.5 server?, I then in turn want to add the server to the new domain so I can then see it, can I add to 2k3 domain. In turn this should allow me to try and install exchange 2k3 again.
Can I do this?
