Sorry to hear that Mike, but it sounds like there are several of us here and on other forums that are having the same issue. We have tried many different things and cannot get it to stop. It was the same for me. The sever ran great for awhile and now it locks up every few days. One guy even got a new box from HP and the same thing happened.

Mine has been doing the same thing recently. The icon will show gray and can not access the server without doing a hard reset.

Thanks for the suggestion DarqMan. I tried a static IP address awhile ago and it has not helped in my situation.

I just swapped out my router and did a full reset to the router for all settings. My server locked up last night again.

This has been happening to me too. First with a HP LX195 and then with an Acer H340 Easystore. Very Frustrating. I had to recover the LX195 a few times and now it won't even recover. The Acer was brand new so I RMA'd it and am waiting for a replacement.

I'm thinking flakey ethernet ports on these things, which would be very bad. The last time this happened, I unplugged the ethernet cable from the router and went straight from the server to a laptop and still couldn't ping it. I tried both straight and crossover ethernet cables. 

Was starting to suspect my router as well, but everything else on the network is working fine. One PC using wired and 4 other machines using wireless. 

I'll try a static ip on the server when the Acer comes back and if it happens again I might also try swapping the wired ports that the server is using with the ones that the PC is using. 

Hopefully we can get this figured out, or else it's bye-bye WHS and hello Drobo. 

I may try to get my LX195 to work again while I'm waiting for the replacement Acer. Last time I tried to get it working, it was failing the recovery process. Is it worthwhile to replace the hard drive and then try to run recovery again? I don't suppose I can connect USB monitor, keyboard/mouse to it?
