We have a computer thats on the internal network but not on the domain and when we try to connect to our Terminal Services servers it says "A Revocation Check could not be performed for this cert" but I have added the Root CA Cert to the Root CA store with Extended Vailidation Info. The DNS points to the Domain DNS server and the hosts file is configured to resolve the dns names as well. No idea on what to do. Our Setup Windows Server 2008 R2 (Active Directory, DNS, TS Server and CA) Windows Server 2008 (Web Server and TS Server) The PC with the issue is Windows 7 Professional

Hi, First let me know if you can access the CRL from the Win7 computer by browsing the location listed in the cert. Also do you use RDP to connect to terminal services. If its, the Microsoft has provided the hotfix for your issues. More Information refers the below link: http://support.microsoft.com/kb/2203302 Finally, if above are not useful, you can post your issues to the Windows Sever Forum to get more professional help.

Hi, thanks. The hotfix appears to have worked and i can now connect. Thanks very much. although i cannot access the CRL (modified it to netbios name) and i can now connect via RDP again thank you Scott
