I am midway through a migration from SBS 2003 to SBS 2008 and have encountred some strange issues. It may be outwith the scope of an EE question but I'm hoping someone can help.
I am at the stage where the SBS 2008 has taken over as the DHCP/DNS server, as well as logon scripts but the old server is still the domain controller.
The first issue I noticed was that I was unable to remote desktop the new server. When I tried it would intermittently get as far as username and password then boot me out. Everything else (on the servers and for clients) was working fine however.
I thought I'd deal with this later but today, another issue occured. Our SBS 2003 was perfoming slowly and a colleague decided to reboot it. Upon reboot, when trying to login to the old server, we got a message stating the domain wasn't available. This machine of course is the domain controller. After rebooting both boxes a couple of times, we got the domain backup and Exchange etc running.
When checking AD Domains and Trusts, the new server seemed to be the domain controller. I manually changed this to the SBS 2003 but it seems to just revert. I presume this happened automatically when the old server went down as a failover but I need to ensure that, for the time being, the SBS 2003 remains the DC.
At the moment, all services are up and running but there is a definite issue with the new box. The remote desktop issue is still present, but what is interesting is that I have installed LogMeIn on the SBS 2008 and seem to be able to stay connected to it constantly, it's just the remote desktop (internal) that fails.
I appreciate there's a lot to take-on here but if anyone can help, I'd appreciate it.
PS - Just to add, on the new machine (SBS 2008), remote desktop outwards seems to be an issue too. If I try to remote desktop the old server, the same smptoms occur (connects for a matter of seconds, then boots me out).
