Thanks Alex...If I may call you Alex.
I have 3 subnodes and 1 central office.
->ISDN lines at remote locations start at a Pipeline ISDN router (10.0.x)
network, I have each node set as a class C, a server at each location.
->Internal ISDN router is a Ascend Max (10.0.1.1)
-> Internet connection is through a Netscreen Firewall, We have a VPN
connection set through this. (10.0.1.2)
-> Internally we use a company called T-Speed for a broadband connection
(Microwave 1-6MBPS) at main location
-> On Node 10.0.3.x we also have a T-Speed Connection
-> DNS server uses 10.0.1.1 as gateway, which forwards to 10.0.1.2 for out
to the internet.
-> I have disabled the 10.0.3.x ISDN connection, and enabled an internet VPN
through my Firewall (10.0.1.2)
-> Windows 2000 Network Main domain is on 10.0.1.x (GC at 10.0.1.20, Exch
Server 10.0.1.30)
-> on node 10.0.3.x there is a trusted domain (I didn't set it up)
-> When we set up the VPN the remote server took all available bandwidth
through the tunnell, and there was no room for other traffic through the
connection. I throttled the connection down to 384k, and I was able to
access the internet.
-> The ISDN is a dual B channell (384K)
-> switching over, I disabled the ISDN connection through the Ascend, and
enabled the VPN
-> Database is on 10.0.1.20 (Master GC) and I if the connection goes down we
cannot access the database, so I think it is all in 1 place
-> Right now I have a router problem, so 10.0.4.X, 10.0.5.X cannot see the
internet, I have a the person who sold me the ISDN routers coming by today
to fix that problem.
-> Before I throttled down the bandwith the VPN tunnel expanded to the full
bandwidth available from traffic between the servers, and there was no
available bandwidth for anybody.
-> I would (ideally) like to be able to have the connection be down and use
the SQL at all locations, but I have security concerns.
-> I think that there is a better way for the directory structure (as in
sub-domains not trusted Domains)
-> I would like to let all connections run at full speed.
-> I have a 512K DSL connection that I will be changing over at 10.0.4.X
once we get this all figured out.

I really apreciate your help on this, I understand what I needed to set up
the Active directory on a local system, but I am not sure once we get to
WANS and routers how things need to be to replicate. Is there a book or text
I could use to help me through this?

Thanks again,
David Bock
