Hi I wnat to implement Domain Isolation using IPSec and I wnat to ask about DHCP. If I use it on my domain and make it in exempt group is this dynamic IP assigning affect my network and the IPsec operation?

No, using DHCP should have no effect on the use of IPsec. If you exempt the DHCP service from IPsec requirements, then you should be in good shape. Use the recommendations for specific services that you run to determine if you should make a particular server statically addressed (DHCP servers, DCs, DNS servers, RRAS servers, etc.).Dave Bishop Senior Technical Writer Windows Server Networking User Assistance
