I'm trying to install Exchange 2003 on a W2K3 Server to replace the Exchange 5.5 on W2K SP4. This is for a small company (50 users) with a single domain.
I've upgraded the domain using Adprep and promoted the W2K3 server to a DC. I've also demoted the other DC to must a domain member. And I switched the domain to native mode as the other three servers are W2K and W2K3.
I get the following error in the ExDeploy log:
- Error: Could not connect to the Exchange 5.5 server 'imsnt1'. Tools that require an Exchange 5.5 server will not run.
A couple of threads posted about this error. One thread discussed not having the LDAP protocol configured. But LDAP is one of the protocols on my Exchange Server. <http://www.experts-exchange.com/Networking/Email_Groupware/Exchange_Server/Q_20947934.html
Another thread goes in depth about the error, but the domain is much more complicated than mine and I can't figure out what pieces I can ignore: <http://www.experts-exchange.com/Networking/Email_Groupware/Exchange_Server/Q_20895254.html
What could be my problem?
