Citrix xendesktop and DHCP error

Hi, am putting a PVS server 6.0 in a lab for training.
Basically I cannot get my windows 7 image to pxe boot and create an image on the provisioning server but I know what the problem is just not how to resolve it.
The pc is broad casting for a DHCP server and instead of my lab based dhcp server responding my Virgin router is. So of course it doesn't have the TFTP server details and bootstrap file etc.
I know I can't point the client to any particular dhcp server but other than turn off dhcp on the router which I don't want to do how can I get around the problem. I'm hoping someone else has come across the problem.
Many thanks

Thank you for responding. Since logging the call I shut down the router and sure enough the client booted toe virtual dhcp server and alls well. I was going to disable dhcp on the router apart from the IP addresses that need access but I'm curios to what you said about putting into a no external network. How would that be achieved exactly?

you have 3 types of networks External, NAT and LOCAL.. I work in hyper-v which have External, Host-Only, Local.. What you need to use is a local network, this network will not exist outside of your VM host.  and you put your VM's into this network.

HI.  So i turned off the router and then bounced all clients that i wanted to use the virtual DHCP server. I then turned the Virgin Router back on. I then found that the clients because they already had their DHCP leases which i set not to expire that on subsequent reboots they always went to the right server for other dhcp options. So thank you.
