Problems with a virtual PDC and DHCP
Hi there,
I am building a network from scratch based on the following cofiguration :
Physical server with windows 2008 standard out of domain running hyper v with a virtual windows small business server as a primary domain controller. I also have a second virtual win 2k8 standard virtualisation.
Small business server premium 2008 allows for this.
All is fine except that when the PDC goes offline machines lose their DHCP configuration, which includes the physical server and a nasbox that the virtual images themselves are stored upon.
What's my best option for managing this effectively whilst keeping the disaster recovery benefits of the PDC being a virtualisation.
Thanks in advance.

This is what I thought had to be done, I just need to work out why the Iscsi device vanishes on the netgear nas box when I switch it from auto to fixed ip.
Why goes the PDC offline, your domain cannot work without PDC funtionality
As for the DHCP clients, if the DHCP server isn't online the DHCP clients will have a valid address as long as the remaining of their lease duration. This is standard DHCP behavior. If you want to shut down the DHCP server for a long time (a week) then you must make sure the lease duration is larger then 7 days.
But Why would you shut down the DHCP server. If that's the case I suggest you use static addresses.
