I have a windows 2003 file server that has been acting really strange today. When you access a shared folder the users PC will freeze up and then nobody can get into any shared folders on that server. I also can not remote into via remote desktop when this happens. It's pretty much like the server just freezes up. This is a quad processor server with plenty of resources run pretty much anything under the sun. When I restart my the server everything will work fine, but then the same the eventually happens again.
