"A network service error has occurred."

I'm having an issue with users being able to log on through the Web Client. They are all getting an error message, "A network service error has occurred.". I can log on to the Admin Console fine. I do however get a message telling me that my license will expire in 29 days but that shouldn't be a problem. Or should it?

I have restarted all services and even rebooted the server. Still no luck...

Please close thread.

Locally authenticated accounts worked but accounts authenticated through AD were not working. Turned out to be a network issue between my Zimbra Server and my Windows Server.
