I have 2 DC's connected at 100mbps to each other, one DC
connected across a WLAN at 5mbps, and one DC through a
fractional T1 at 3mbps. All are running AD integrated DNS
zones. I have set the remote servers to replicate once
every hour. Since I have made both remote servers DC's our
internet speed has drastically slowed down. What settings
should I look for and how can I test to see what is
causing this slowdown?

ASsuming you created Sites and you set the replication frequency to 1 hour
on the Site links, I would put it back to the default 3 hour frequency.
Also, ensure that each DC on each side are both GCs. That will cut down
logon and authentication traffic as well (which can be a bulk of it). Do
you have Exchange running? If so, Exchange needs the GCs exclusively. If you
have an Exchange server on both ends, then in each server properties (in the
ESM) force the GC that its using to the one in that Site only.

The problem was actually malicious mail traffic. I was
receiving 30 messages that were over 100MB in size...each
time the mail server was restarted, the network speeds
would pick back up. Haven't had any problems since then.
