This rings a little bell for me.. I've never seen 10055 in a log but I've
seen 10054 a fair amount in both production and development.
In development, if it's 10054 then client apps being "reset" while running
may be the cause and not faulty NICs under these circumstances.
But in production, if it's 10054, then it may be the PC getting
Ctr-Alt-Del'ed which cuases this log entry and also not a faulty NIC.

OR is it indeed 10055?
