Hi Everyone,
Multihomed DCs are more trouble than they are worth and can lead to all
kinds of replication fun. Tim does make a good point, though.
The piece of equipment you are missing is a router to get you from one
network to another -- this could be inter-VLAN routing on a switch, a
physical router, or a server running RRAS to route between the NICs.
If you have the equipment and enterprise need to justify an additional site
for redundancy, you would probably be better served acquiring the network
equipment to do it correctly. I am a big fan of only asking equipment to do
what is in its sweet spot. This means avoiding routing on servers,
especially DCs, if at all possible.
If you're stuck with home class equipment like linksys, you might be better
off getting a combo router/ switch for $40 and using the uplink port to
connect back to your main LAN segment. You'll have to work a little more for
it, but it'll be much more stable. Of course, I would strongly suggest
investing in Cisco gear, but I'm sure you would have already if it were just
that easy.
Cheers,

Hi there,
So I have been discussing a project with a MVP on another newsgroup and know
what i need to achieve. Just need help with it.
Basically i need to create a "fake" site.
I have 2 DFS-Store servers (2 servers with a copy of the same data).
I need to put the second on a new site, with a VLAN on my switch so DFS
thinks its an Off-Site replica. When really it would help me resolve my
failover requirements.
So....
Hand Built PC - SBS2003 SP1
DFS-Catalogue - Brand New Dell PowerEdge 860 - 2003 R2
DFS-Store1 - Brand New Dell PowerEdge 860 - 2003 R2
DFS-Store2 - Brand New Dell PowerEdge 860 - 2003 R2
DFS-Catalogue : ---> DFS-Store1 (Master)
: ---> DFS-Store2 (Replica on fake new site & new
subnet)
I need to create a way, in AD, to add a new site, and a new subnet for my
VLAN and then physically link into that VLAN somehow? I dont understand how i
need to link the existing switched machines to a VLAN port group. The Netgear
GS725T Switch doesn't offer the chance to assign a Subnet to the new created
VLAN port-group.
Basically need to trick AD into thinking that the DFS-Store2 is on another
site, and put a higher cost on that connection. So users on the first site
talk to the DFS-Store1 only. But need to create a route so that, if
DFS-Store1 was down, the users would be switched over to DFS-Store2 on what
seems to be another site.
Thanks in advance.
