BIND 9.2.4 on a Dell 1655MC

[Fr34k]

Hello,

Is there a NIC power save option (or similar) you can disable in BIOS?
We had something similar, but I can't recall if it was a Dell.

Sorry that I can't recall the specifics, but perhaps it may be the issue you
are seeing and I mention it in hopes that it is.
