I have a windows 2003 standard edition server with service pack 2. Every day i need to reboot the server because port 3389 is not longer open. This started about two weeks ago, long after sp2 was installed and a year after the server was put into production. RDP has always been used on the server.
No new software was installed on it recently, except windows updates.
I checked around this and other sites for help with no luck. Most cases had a specific issue that caused this problem, mine didn't seem to. Just stopped working and works again with a simple reboot.
