There are only 30 users on this network, so maintaining dual lists of users is not really an issue.
The clients want to use MS Exchange to sync contact lists, schedules etc, which I have been unable to do with open Xchange. if there is a way, that is an option I am willing to look at as well.
If I tell the SME server it is not the domain master, will that still cause a problem with the SBS2003 server??
I had thought that would not cause an issue. I still need to be able to use the SME server for proxy and port forwarding, nothing else.
When I go to join a local computer to the domain, and insert the full domain name of the SBS server, it returns an error, could this be because of the registry hack perfomed to get the local computers to join the SME server domain initially??, if so, I can reverse that.
