What a pain. Sorry you have had to go through all of this.
To start somewhere:
The sbs 2008 group can be found here: http://connect.microsoft.com/SBS08
You could post back here, either with the information I am about to request,
or to close this thread and move your original post and the new information
to the SBS 08 group, just don't do both groups at once.
To start with: can you please give us the unedited results of:
ipconfig /all > c:\iptest.txt
And, have you run the SBS BPA and fixed everything it finds? www.sbsbpa.com
Please post the resolution to your
issue so that others may benefit.
