I have one problem and i hope that you can help me with it.Post will be
little longer i hope this would not be a problem to you.This is the
situation.

I have a single domain with 8 sites.in every site i have two DC.One DC is
global catalog.Site are connected with central site with 128 kb link.Only
one site has 1 Mb connection.I have DFS with one root and i create
replication to occur after buissines hours.I have wery strange situation.In
certain times my server have very high ping.After i restart file replication
service everything seems to be ok.First thing that i think that could be a
problem is Sophos Antivirus on server.Second thing that could be a problem
is low memory on my servers.Some servers have 256 mb.That could be a
problem.I have a fully routed network and i create connections from my
server in central site that holds PDC emulator role to every GC servers in
every site.I have turn on bridge all site links.AD replication occurs within
site every 15 min(For time in our) and within site once per
hours.Replication is not scheduled.We have wery restricted Gropu policy on
XP machines.


Is this links to slow for this kind of domain?Should i schedule AD
replication on site links to occur after buissiness hours?
With link of 1Mb i don't have so much problems.
Is Sophos antivirus a good solution for my DC?
Do you think that increasing of memory on DC's will solve the problems?
Do you think that i should turn of bridge all site links in this situation?

All test are seems to be ok netdiag,addig,dcdiag and all others.

[Christoffer Andersson] This depends on how much daily changes you done in
AD and how much users you have, also how big is the replicated DFS root or
link?
