Oops. I missed the fact that we are dealing with DCs. No RRAS.
Setting it up should be about as simple as you've listed. Router between
the networks, new subnet object, new site then configure DFS. BTW- I've set
this up before and it works very well. Replication is quick and failover
only took a few seconds in some cases.

Yea its cutting to the crunch now..
I just want my replica DFS server to be on another subnet but physically in
the same server room, appearing to AD as though its remote.
Just wondering if the "Existing Switch w/DC & Primary DFS Store>Router>New
Switch w/ Replica DFS Store" is a working model or will it just go down like
a led zep.

Chris,
Just for completeness, you could do something creative with subnetting, but
frankly the time it would take and the risk of creating other problems make
it just not worth it.

Hey guys,
Thanks for your replies so far.
I was warned off the RRAS service for this type of network challenge.
We have some good rack routers just sitting in the cuboard.
Would it be as simple as putting the router between the existing switch,
and
a new switch with the second redundant server/dfs replica on? Then using
AD
Sites and Services to create a new site, then inside that, the server
object
and subnet object for that server?
I know this is a networking question really, but I know you guys are very
multi-skilled.
Thanks for your time!

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,

Here's an outside the box solution. Put 2 NICs in the server and use
routing and remote access to actually create a second network. Real
site,
real subnet. No VLANs or switch configs.

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.
