<servername> : The browser driver has received too many illegal datagrams from the remote computer EHZW8CYGAI2OEJR to name <domain> on transport NetBT_Tcpip_{95A63A61-6884-4. The data is the datagram. No more events will be generated until the reset frequency has expired.

I am getting these every few days on my PDC in one of our Windows 2003 Domains.

We run one of the largest AD infrastructure on earth (according to Microsoft) with multiple forests. This particular error is from the child domain of our main user forest.

I have checked the PDC out and it is fine, well, in terms of AD there are no issues.

I am unsure what this error means as Microsoft say it could be an attack or maybe nothing more than dodgy nic drivers.

Anyone got any ideas?

We are running Win2k3 Forest Functional level on 64bit with SP1. It all runs on HP DL380's (G4's and G5's). None of the drivers have ever been updated from the original builds and no other servers are showing this error.

Well I can't really add much to what you have already been told - faulty NICs and/or drivers could be responsible or you could be under attack - you could monitor the network and try and determine the source of the packets.

Hmmm... the problem went away on its own. Dunno what caused it to be honest.
