QuestionIf you have DHCP set up with multiple scopes and one of the scopes has a lease time of 0:0:0 what would the effects be. For example would would clients experiance multiple dissconnects?

Hello. You can't set the lease duration to 0:0:0 that it is recognized as invalid in the Windows DHCP server. In the scenarios that a scope that has a short lease duration, client will only attempt to renew the lease on background in a short interval. It will not experience network disconnect because it can renew the IP address lease.
