Remote Desktop Error

Hello All,

I hope this is the correct group to post this question
to. Sorry if it is not. I am running Windows 2003 Web
Server edition. Several times a day while accessing the
server via Remote Desktop I receive the following
error: "Because of an error in data encryption, this
session will end. Please try connecting to the remote
computer again." I have searched the knowledge base and
this newsgroup and can not find any solutions. This is a
brand new install of Windows. Actually I have been
testing on it and have installed many times. Each time I
still get this error. I have the server behind a
firewall, but have another one behind it as well and have
never experienced the same behavior with the other
server. Any help would be greatly appreciated.

Thanks,
Greg
