I have a client using Windows 2003 Server that is have an intermittent issue.
The server will lose connection to the internet. It is unable to ping yahoo.com or yahoo.coms IP address. The server will however be able to ping local computers and the workstations will not lose access to the server.
Routing and Remote Access is enabled and the server has two NIC cards since there are users that need to VPN remotely. When I installed RRAS, I ran the wizard to set it up and dont have much more knowledge on the subject.
The way to fix the issue when it happens is for me to remote into the server using Remote Desktop or have them restart RRAS. Both will solve the issue until it happens again which can be anywhere between a couple of hours to a couple of months.
Ive replaced the network cables going from the server to the switch (just in case) and was going to replace the NIC card as well just to make sure it isnt some sort of hardware problem. Before I did that, I wanted to check with the experts here to see if you folks had any other ideas.
