Hi,
I have the following setup with 2003 DHCP servers on the same segment :
DHCP1 - scope 192.168.0.1 to 192.168.0.128
DHCP1 - scope 192.168.0.129 to 192.168.0.254
Lease time is set to 1 day. Both scopes have the same scope options. I've recently noticed that DNS A records aren't always registering properly and that on a few occasions (around 1 in 8) DHCP clients have an active lease on both DHCP servers - i.e. the client disconnects from the network for a while, tries to renew it's lease, but can't for one reason or another and ends up gaining a lease on the other DHCP server.
I'm in two minds whether to use a superscope which encompasses both scopes, but has exclusions for each server or upgrade to 2008 and use the split scope DNS wizard with appropriate DHCP response delay.
Most of what I've read about superscopes mentions they're used for multinets, but that's not what I'm trying to achieve here.
Ps - whilst 2012 is an option, it's not something I'm strongly considering at the moment.
Thanks
