I am running Windows 7. The LAN connection keeps disconnecting. After the user logs off the LAN will not reconnect. I have to disable the adapter and then enable it again for it to work. This is on an HP TouchSmart 9100 that is less than a month old. We have 12 other desktops exactly alike and this is the only one doing this.

I have had the same problem and I still don't know how to fix this. Could you please let me know how to fix this when you find a solution? I'll do the same. Cheers.
