The new NIC is in, but not running off of it just yet, we are working on reassigning IP addresses and will make it live very shortly.

went to do switch, and new nic is not coming up, working on it.

Things are not going so well here, no packets are passing on the new NIC at all.

I am very sorry, this was not expected to take anywhere near this long, we've done several NIC changes int he past and never had an issue quite like it.

Right now win16 is up with the original nic that was experiencing some packetloss, because it seems not other NIC will work, zero packets will pass.

There seems to be some freak bug we've encountered here in windows, as we've tried two Intel server NICs, and an IBM marvell chipset NIC, and there is no way all are bad, especially since one came from a testing server that was working fine last week.

There is still just less than 1% packetloss at times on this nic, and we are working to get all resolved, but at this point we wanted things back up and going.

We have tested quite a bit since then, in high network, high cpu, high IO times (we forced them) we are no longer seeing any packetloss, even on the original NIC.

So, it is for now resolved, we will keep a close eye on it.
