This is not hard to sort out each domain keeps its DNS rolls just DHCP will sit on one domain with reservations set for the least amount of workstations guessing this would be the admin network and the main scope setup for the curric doman. just might take a while to eneter all the mac address but it works well

What Antivirus softwaere is the workstations and servers running. Have you tried rebooting the servers what happens if you rebuild a workstation.

Hi At what point are the computers failing to build. If they are failing at adding computers to the network this could be related to a DNS issue. Do have the admin and CC4 on the same subnet ? and are they on different domains ?. Do you have any idea which virus you have on the network

Hi I have no idea what this software does but by the sounds of the problem It could well be network. The rooms which are haven the problem are they on the same switch. The reason why I ask is that I have seen a simlar problem where the connections between the switches need to set to the default speed IE 100 full duplex and disable spanning tree or even the switches firmware needs updating. The problem could be the envoment Ie the workstations are running to warm in there present location. Hope this helps

reggiep Are you running this as the Demo or full version. If your running as Demo then theres a RM tool called appication wizard which allows you to import the MSI straight into the packages without trying to repackage it. If its the full version then the software house do provide a version for CC3 package but I am sure its not that hard to repackage it
