I'm not sure if it was a recent Windows update within the past few months or what, but my farm of 100 Windows 2003 Citrix servers have begun to stop accepting RDP connections. I can go to the console in VMWare and login and uncheck the enable remote desktop and recheck it, and it will work again. Also, I can reboot the server and RDP may or may not work again.
I even rebuilt our current Windows 2003 template from scratch ran Windows updates. Still I see the exact same problem. Nothing seems to fix this. Is there an update or a fix for this? Is anyone else experiencing this?
