First of all, I have a cisco router that I'm configuring with the SDM express.Should i configure the router as a DHCP server as well as another server within the network with the same pool?Or should it just be the router.Also, the router has a 192.168.1.249 gateway.Users can see the network on both the 192.168.1.1 and 192.168.2.1 sides but only connect to computers on the 192.168.1.xxx and not the 192.168.2.xxx side.Any suggestions?

1. You only want one DHCP server serving a particular pool, if you have 2, they might issue the same IP address since they wouldn't know what leases the other had given.

2. If I understand the 2nd part correctly you have an internet gateway at 192.168.1.249? If that is so all PCs, both in 192.168.1.0 and 192.168.2.0 would look to the router as their default gateway. If the route was outside the two connected networks the router would then send the traffic out 192.168.1.249.

Users on the domain can log on using this router(which is setup wireless) They can run apps , email on exchange, etc. but when trying to connect to servers on the 192.168.2 0 network, they cannot.I guess I want the best of both worlds.I want guests to be able to access the internet fom inside and I also want domain users and admins to be able to log on to the network as well.

Computers in the 192.168.1.0 network would have their gateway as 192.168.1.1 and from 192.168.2.0 would have their gateway as 192.168.2.1. The router should handle all the IP traffic between the two. Then the router's gateway of last resort would be your internet gateway (192.168.1.249?).
