LDAP traffic between DC and Component Server

[Guest]

I have been observing a high network utilization (higer than 50% prom)
between an AD Server and a Componet Server. I downloaded and make a capture
with Network monitor v3 and I get mostly the same kind of frames:

LDAPError: Unhandled LDAP data
UnhandledData: Binary Large Object (1460 Bytes)

The AD is in another domain/forest than the component server and they are in
different IP subnets. The component server also communicate with its AD but
in a minor proportion. The conmunication to the DB what we expect to be the
the only one or the big one is less than 1%.

Any ideas?
