W2k3 AD Server spewing to 224.0.0.251.mdns

  • 772

I'm looking at a tcpdump of my network and seeing floods of mdns packets from my W2k3 AD Server. :

03:28:30.655189 IP mydomainserver.local.mdns > 224.0.0.251.mdns: 0*- [0q] 1/0/0 A 192.168.100.1 (40)

Why is it doing this and how can I stop it?

windows-server-2003 active-directory mdns

    This is from installed software (which is a little concerning on a domain controller).

    Check through Add/Remove Programs, and get rid of anything that shouldn't be there.
