Well... I THOUGHT that I'd turned the Windows Firewall OFF but apparantly I just turned part of it off. It is now completely off and my clients are registering as I type. Thanks for the clue!

Just a quick check here... when you say you turned OFF the firewall on the server, do you mean the SEP firewall, or the Windows Firewall - WF is on by default with 2008 and will block incoming client requests... just want to double check you have both turned off, or at least are allowing the SEPM ports through it?
