When trying to connect to a Windows XP Pro w/SP2 computer from an XP SP2
computer with RDP (6.x), I get the following error on the target computer:

This is irregardless if the user is allowed, Local Administrator or Domain
Administrator.  There are NO problems connecting to any other computer.

I found MS KB 323597 and others that mention the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService\Parameters
Key, and deleting the Certificate and X509 Certificates.

On that computer, there is ONLY the Certificate Value, the two X509 Values
are missing (on our other computers, all three Values are present), so...I
presume I need to somehow create or recreate them?

I couldn't find information on doing that...what do I need to do?

Thanks!
