Cannot RDP to Svr2008 or Win7

I have one Windows 7 computer that cannot RDP to Windows Server 2008R2 or Windows 7. Can RDP in Windows XP.

I have tried a couple of different computer with same version of OS & RDP Client and they all work. Server is already set to allow less secure connections.

I do not see any errors on the clients events. I do see the errors on the hosts events.

Sounds like network issues. Try updating/reinstalling the drivers for the NIC on the PC and setting the speed to Auto.

I've updated the driver and the speed is set to auto.

I am asked for credentials and then I get the error.

This computer can't connect to the remote computer.
Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator.

I have also tried a network connection that I am able to RDP with on the machine in question and I still have the same problem.

This article may be of some assistance -

http://www.neowin.net/forum/topic/912688-windows-7-repair-install-cannot-connect-via-remote-desktop/

To get to the point of the article, it states -

To resolve the issue, I went into the Certificates console (for the Computer Account) and deleted the computer name certificate from the Remote Desktop certificates folder (after backing the certificate up for good measure). I then disabled Remote Desktop and re-enabled it (I don't know if this step is necessary, but I tried it, thinking it might regenerate the certificate). I then tried to connect from my remote machine, and it connected just fine. It appears that the certificate re-generated on the initial connect after I deleted the certificate.

To access all of the certificates, run mmc.exe and add the certificates snap-in (note - if you access the certificate store by running certmgr.msc you can only edit the User account certificates). When you add the certificates snap-in, you get the option to access the certificates for the the Computer account as mentioned above.
Your help has saved me hundreds of hours of internet surfing.

I had found that as well. I removed the certificate using mmc.exe and the snap-in. Disable remote desktop through Advanced Systems Settings, by clicking "Don't allow connections to this computer". Then turn it back on.

The certificate does not get created until I restart the computer.

It did not resolve the issue for the workstation (client) with the problem.
