I have a Windows Server 2008 R2 Terminal Server that randomly will stop responding to pings. When this happens the users that are on the terminal server can still work. However, no new users nor i can remote into the server. I nor anyone in my network operations center can ping the server when this happens. The only solution that we have found is to reboot the server. Has anyone come across this unusual behavior? If so, were you able to fix it and what was the fix? Thanks for everyone's help with this issue.
