Domain controller broadcasting large chunks of data

I have a W2K3 SP1 domain controller with Global Catalog and FSMO roles as
well as running DNS that for some reason the other night broadcast roughly
17MB of SMB traffic to every host on it's local subnet (caught with a
network monitor). Nothing in the server's logs to indicate that, and it
appears to be clean of spyware/viruses. Can anyone suggest anything with
the services it's running that would cause this? We have two other domain
controllers, an Exchange 2003 Server, and about 600 clients.

Thanks in advance for any ideas,

Phil

we had an issue once were "some how" a bunch of data go coppied to the
sysvol and wasreplicating to all the dcs...Check that maybe.
