multiple domain controllers (DC) on the same LAN

Use the DHCP of one of the DCs and split the LAN into 2 SUB-LANS
this is done using a superscope in the DHCP of domain controller.

- one scope 192.168.1.0/255.255.255.128
- another scope 192.168.1.128/255.255.255.128

The two sub scopes will not be able to access one another

Put one of the servers in first scope and the other in the second one.

In the scope options each have their own DNS and default route

To make the clients become a member of a certain scope fix the clients MAC address and create a reservation

vmware guest OS on windows RRAS host OS problem

If you need to have vmware installed on a machine with RRAS, because of incompatibilities between proxy arp of RRAS and vmware your guest OS packets will not be routed, what you need to do is:
[in this example host machine has 2 NICs. One toward Internet and one local.]
1. Add a NIC to the host machine. (not virtual)
2. In the guest OS bridge one NIC to the Internet NIC of the host OS and the other to the newly added NIC of the host OS (which is connected to the local LAN)
3. Assign an IP address to the host and guest machine (the same range as the host machine)
