Windows 2008 R2 Certificate for Remote Desktop Expiring, how to handle this?

On Windows Server 2008 R2 I was reviewing my certificates and I noticed that the remote desktop certificate is expiring soon.  It is a non trusted certificate according to the mmc.  I never had to renew anything in regards to this on Windows 2003.  Need to know if I have to renew this or replace it and how so that I can still remote into this server after this expires.  Or maybe there is no impact. Can someone please help me with this.  Thanks.

"Turns out restarting the Remote Desktop Configuration service will renew the certificate if it is expired. I did not have to delete it first however I did test on another server by deleting it then restarting the service. It still properly created the certificate. Doing so generates an event log message:"

So I think he is saying that if I just restart the remote desktop service AFTER it expires that would fix this.  Is that what you think will work.  I tried it wihtout it actually expiring and no change to the certificate occured??

In one case we deleted the soon to expire certificate from the Certificate Management Console -> Computer Account and then restarted the service and a new certificate was created.  So you can manually delete the certificate and restart and it will create a new one as well.

It will not create a new certificate until the one that is there is either deleted or expired.

Well that did work. I deleted it and it recreated it but it gave me the same time lenght.  I guess I will have to do this again when it expires. This information was a great help. Thank you.
