RDC - Remote Computer cannot be verified

Question

When I finally got my Win7 Home Premium Notebook to connect to the Win7 Pro dekstop a pop-up box appeared stating, "The identity of the remote computer cannot be verified.  Do you want to connect anyway?"

It had a section Certificate Name (which was my computer's name) followed by a section called Certificate Errors which stated, "Thi certificate is not from a trusted certifying authority.  Do you want to connect dewspite these certificate errors?"

There was also a View Certificate button and an opportunity to download/verify the certificate.

What is this all about?  Never saw anything like this with the Win Xp Pro remote connection.

Answer 1

Are you using Network Level Authentication [NLA]? If so you could try disabling NLA on both the Remote Desktop [RDC] host machine and client as a test (ie. not a permanent fix).

You can then try removing the certificate from your RDC host computer by going toStart | Runand typing mmc.msc, adding the certificate snap-in and deleting the Remote Desktop certificate then connecting again as a permanent fix.

Note the comment about making sure the date and time is set correctly (on both the RDC host and RDC client) in this old thread from the Vista forums that deals with this issue...
