You guys might try assigning a static/reserved IP to the server in your router. I was having connectivity problems and the static IP did the trick for me.

I was having the same problem. Traced it back to the router. I believe the router was overheating and dropping the connection to the server. I upgraded the router and haven't had the problem since. Old router was Linksys WRT310N, new is a Linksys WRT610N.

It could be a flakey system drive. If you have an extra drive around, you could try replacing the system drive and doing a factory reset.

I had the same problem. Traced it back to my clock not being set to the right time. My computer had a dead battery (for the clock) and every time I shut down the computer, My system would lose the time and the server icon would stay gray.

I've got the same exact problem. I have a WRT610N router, and have assigned a static IP to the my server. The server does answer pings but does not respond to terminal sessions.

Anyone heard anything back from HP?

I hope that this issue gets solved. I am having the same issue with the server dropping off the network. I have to do a hard boot on the server to get it back on line. I know that is not a good practice but the only option to recover the lame server. I have done a factory recovery 3 times with no favorable results. All suggestions would be most welcome.

Thanks for the reply Mike. I think (hope) I might have found the problem. I have Avast running on my server and I picked up a bug. Avast found it and I was not informed of this immediately. Avast had quarantined the file. I did not acknowledge this and every time it gave me the notice it locked up the server waiting for my acknowledgement. I have dealt with the file and ever since (2 days now) the server has kept its network connection and I am bug free. I will post back if it fails.

I had a number of problems but they probably were all related to losing connections.

I have an EX495, 2 HP Desktops running Win 7 Ultimate and a Toshiba laptop running Win 7 Ultimate. All are connected to a Netgear GS108T which is connected to a Time Machine router for Internet access. So, except for the laptop, everything is running on Gigabit Ethernet.

I fiddled with the Ethernet device settings to optimize my network performance. Seemed to work OK at first but then I started experiencing connection losses and backup failures on everything except my laptop.

Connections could be restored simply by unplugging and replugging my Ethernet cable into the MSS.

A couple of days ago, I set all of systems (including the WHS) to the same settings as my laptop which were probably the same as the original defaults. Everything has been work well since so probably everything would have been just fine all along were it not for my "improvements."

I'll probably fiddle some more and it may give me a better handle on what doesn't work as well as what works but won't post my settings as your setup probably isn't the same as mine. But if you are having connection loss problems, you might want to compare your Ethernet device properties on all your machines.
