One of our Helpdesk personnel got the following error when making an RDP connection from Windows XP SP3 to a Windows Server 2008 R2 server, "Remote Desktop cannot connect to the remote computer because the authentication certificate received from the remote computer is expired or invalid. In some cases, this error might also be caused by a large time discrepency between the client and server computers." It's purley for administration purposes. We aren't using TS Gateway or anything like that. I have double checked& the date, time, & time zone on both the server & client & they are all correct.
On the server if I open the certificate store in an MMC & browse to Remote Desktop\Certificates I see that the self-signed certificate expired on 5/3/2011. If I look at the same store in other 2008 R2 & 2008 SP2 servers they all have a self-signed certificate as well but the date it still valid. IT appears as though this certificate should be renewing itself automatically every 6 months but for some reason on the one server it is not. Has onyone else seen this issue before? What is the mechanism that is supposed to renew this certificate?
Thank you in advanced for any advise.
