its a wired network. and yes the other pcs are on when this happens. My desktop is not the only one that experiences this, but mine seems to lose network systems more often. For the last two days, I have rebooted my desktop many times and finally at the most got 7 pcs on our network to show. The one I needed happened to be one of the pcs that never showed up on the network. lol
Ken, when you say what is the network setup, what specifically do you need to know. Now I am not at work presently and wont be until monday morning. As I said earlier, all the pcs are running windows 7 as far as I know. All seem to be wired to a central computer running windows 7 as well that is simply used for data backup storage. I mean its not running a server environment.
I really dont know much about the router or switch, so cant comment there either.
I was hoping there might be some simple basic steps I could take to test network connections. I have run the network diagnosticson my own pc when it couldnt find another pc, but nothing helped there.
