Unlike SBS2003 where some very specific patches were created for both the SBS 2003 server and Vista machines joining those domains, nothing is available (nor will anything be coming) provide compatibility between Vista and SBS 2000.

You may have to try the restore on Vista in Safe Mode and I would logon to the Vista Machine as the Local Administrator account.

 I setup RADIUS on the SBS2K server and changed the WiFi encryption from
 WEP to WAP using RADIUS.  A Windows XP laptop seemed to work fine with it.

 I then plugged a network cable into a stable Vista laptop, joined the
 domain, then configured the WiFi on the laptop to match the router's
 settings.  After doing that, I unplugged the Ethernet cable, logged out,
 and logged back in on the Vista laptop.

 During that process, I added a domain group (which includes the laptop's
 user) as a member of the local administrators group on the laptop - just
 as I do on the WinXP machines.

 I'm now getting all sorts of wild and crazy error messages on the Vista
 laptop, most apparently have something to do with
 ownership/security/permissions on files and folders.

 I tried to manually add the domain user to the file and folder
 permissions (full control).  In vain.

 I tried to run a System Restore on the laptop to the day prior to all
 this.  It ran, then upon rebooting, it said that the System Restore
 failed to complete successfully.  I then dis-joined the laptop from the
 domain (put the laptop back to using a workgroup).  I also reverted the
 security settings on the router and the laptop's WiFi connection.  Then
 I tried to run the System Restore again.  The same error again.

 Has anyone had any similar issues with Windows Vista?  Any suggestions
 (besides throwing the laptop out a window on the 14th floor)?

 Thanks.

 P.S.: I've gotten budget approval for a complete upgrade - New O/S,
 CAL's to go with the new O/S, and a new server to run it all on.  The
 catch - it is slated for just after SBS2008 hits the shelves.  Until
 then, SBS2K is my cross to bear.
