I find it pretty crazy 1yr to the day later, I'm still having  this issue.
I tried what you suggested Denis and I get the same results.  The only thing
I can think of, when I built the server (+4yrs ago) I ran several 'lock
down' procedures and one of those might have removed the ability to be able
to add the TAP-Win32 device.  I don't know -- grasping at straws here.

In researching this issue I ran into a post about the RunOnce key possibly
missing from the Registry, but that wasn't' the case for me.  It was there:
1. Go to Start Run and enter "regedit."
2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
3. With CurrentVersion Highlighted, go to the Edit menu and select New Key
4. Name the key RunOnce, leaving everything else about the key alone.
5. The RunOnce key should now exist underneath the CurrentVersion key.
6. Once the key exists, Windows 2000/XP stops redetecting the Hardware

I sure would appreciate it if anyone has any other suggestions.
