Can't connect with Upgrade Advisor

I'm having trouble connecting the Upgrade Advisor to a SQL 2000 box at a client. Here's the setup:

1> I'm running UA on a Virtual PC image

2> I can run UA against other SQL machines on the same domain

3> I can register and administer the SQL server I'm having trouble with in Enterprise Manager

4> I have SA rights on the SQL box I'm having trouble with.

5> The problem is when entering the server name and clicking "detect," it errors out with "The network path not found (mscorlib)."

6> I've tried server name, FQDN and IP address.

This is a fairly convoluted layout, so there could be a firewall issue that I'm not aware of (but I don't think so).

Any help would be appreciated!

Bob, have you tried running UA directly on the target server? It shouldn't be a problem unless the OS level on the server doesn't support UA.|||

Hey, Allen. Thanks for the feedback...as we discussed Thursday (but I mention here in case anyone else is interested), I don't want to add the .Net Framework to the server at this point.
