When you say PDC, I am going to assume you mean the FSMO role PDC
Emulator which runs on a Domain Controller. NEVER CLUSTER A DC.
NEVER. With that said you don't need to cluster a DC anyway. Just
have 2 or more, since FSMO roles never automatically transfer. Use AD
integrated DNS too, so that DNS is available.
1. Cluster over a WAN? With one node a each location? Only if you
have third party replication for the shared storage and two SANS.
Exchange Server 2007 has other options when SP1 comes out, but
nothing right now. You will need to have under 500ms access times
between the servers. You will need 2 VLANS for the clustered nodes,
one for the heartbeat, one for the public traffic. This is a must,
same subnet for the nodes!!!
2. If you still have bandwidth available, what else runs on it? Do a
ping test, and see number 1 for issues.
3. Exchange can. NEVER CLUSTER A DC!
Hopefully this makes sense.

I've been tasked to set up a PDC/Exchange server that is currently
running Windows server 2003 std R2 With a redundancy solution that
would involve having another server at a remote site. Whenever the
PDC at the host site goes down it must failover to the remote site
with minimal fuss.
I'm aware that the current setup /software/OS won't work with
clustering and wanted to purchase server enterprise edition and
exchange enterprise edition at both sites to comply with the
requirements of the task.
The connection is a 2Mbps bonded ADSL line.
I have a few questions about whether the setup would actually work
over a WAN cnnection. I've read various documents and articles on
the net saying that this is no problem but had a few questions
1. Is it possible to cluster a server and exchange 2003 over a WAN
2. Would a bonded 2Mbps ADSL line be enough to allow replication
over the WAN link
3. Would a Cluster server do what I want i.e allow the node to
failover and allow network users not to notice that the PDC had
Thanks for any insight anyone can give me into this subject.
