hi everyone...am facing some problem at work. we have a win 2003 domain controller and it has no problem ACCESSING ht net. there are 2 lan cards in it. one with the range of a 10.10.x.y ip and the other with a 192.168.x.y...the clients are running win xp and are getting an automatic ip of 192.168.x.y..since the routers wire is in the 10.10.x.y lan card and the switch wire is in 192.168.x.y lan card..the domain controller has internet...but for some reason the clients seem to have a problem..NONE of the clients can access the internet..they can ping with domain controller..the router and even share files across the network.

IF i remove the routers wire from the domain controller..and PUT it in a switch..and put the switch wire..(which is currently in the 192.168.x.y lan card) and put it in the 10.10.x.y lan card..the domain controller gets an ip from the 10 range..so do the clients..and they ALL can access the net..but when i do what i have mentioned above in order to make the clients get an ip of 192...the net doesnt seem to work..i really need to figure this out..your HELP is great appreciated..thank you all..2 card suggest maybe one is Ethernet and the other ? Have to give a little more infor like what type of card (brand) and how many PC. The 10.x.x.x. is in the range of a private IP Address and the 192.x.x.x. is in the range of public IP Adress. It might be looping between the router and switch hance the STRANGE IP problem. The Domain controller in which device is it connect to the switch or router? I assume it is the router that is why u r getting to the internet. What is the switch connect to? write back and let us know.there are about 7 pcs...the routers cable is going in the 10.10.x.y lan card and the switches cable is going in the 192.168.x.y lan card..meaning that both of the ethernet cards are occupied...there is a dhcp configuration as well..the range is 10.10.x.y and the scope is 192.168.x.y....this is how am getting the 192 ips on all the clients as well as the domain controller..but the problem which persists is the fact that they dont have internet when they are automatically getting an ip of 192. but when they are on 10.10 ip...its all fine...do you think that i should give the dns on all the clients statically?...would it help?Aright first do not use both cards. Try this,from the domain controller card connect a Ethernet cable to the switch. What this basically will do is give u internet connect and a intranet connect. The client should be able to network with each other and still have internet access. U might have to set up Active DIRECTORY to give permissions to client. Follow the Link below for a explanation on how to.

There is really no short cut on do this, but following the article link. If u look on the left plane u might want to go the Win 2003 server explanation.

Good luck.
