SBS 2011 Network Connectivity Issues

Hi,

I have a Windows SBS 2011 Installation and the client computers seem to periodically and randomly lose connectivity to the server.

The can be working away no problems, then all of a sudden they will lose access to the server, yet they can still ping it. It happens during a lot of different things. It even happens to me when I am RDP into the server, it will just error saying cannot connect, retry's 20 times, I can still ping it. However it disconnects, I wait a minute and it starts working again.

What could be the cause?

Thanks

Mark

Have you tested Hardware (switch, router, etc...) to make sure they are not faulty. You could be having some sort of connectivity issue between a switch and router or switch and server, causing the intermittent problem. Also run the Fix My Network Wizard (FNCW) ( if you haven't already, Good Tool) in SBS Console. This can help find other issue's unknown that might be the issue.

I have run that. I haven't tried replacing the router and switches, however as I can still ping the server. Its weird.

try a TRACERT rather than a ping to see if you can narrow down where the dropout is...

Found the issue, someone setup another device on the network with the same IP as the server.
