Potential Problems

Usenet · Mar 6, 2007

Over the weekend we are merging two office into one.
At the moment each office gets an IP addresses from their local dhcp server.

With the merging of the offices can I make a primary and backup dhcp server?
All using the same ip range?

Trying to foresee any problems, Is there anything else I need to take into
account from the merging of the two offices?

All the servers are on the same domain & are windows 2003

Define "merging". Same room? Same company? Same what?

Same "range" doesn't always mean same subnet. Same subnet?

If the same subnet then each DHCP is configured with an identical Scope. Only
the Exclusions are different. Generally the Exclusions allow each DHCP Server to
give out 50% of the addresses.

account from the merging of the two offices?

Depends on what "merge" means. If they are in physically different locations
connected by a slow WAN Link (anything less than 10mbps), then they should:

1. Be different subnets,..*not* the same subnet
2. Each has their own separate DHCP serving just there own subnet
3. Each should have there own DC/AD/DNS Server (same domain, or
at least same Forest)
4. Use Active Directory Sites Object to control Replication over the slow WAN
link.
Sites Object requires each Location to be a different subnet.

All the servers are on the same domain & are windows 2003

Doesn't matter.
