I am running a single instance of 2003 Server inside of a VM. The internet and network connections inside the VM are working fine up until I add a 2nd IP to the NAT, at which point I lose my network connection to the VM. I also set a "reservation" for the 2nd IP to direct to the internal IP of the VM's Network interface. If I look in the Window Event Viewer I see a lot of 20106 errors show up as soon as I make that change:

Unable to add the interface {4687FB18-B1A7-4B82-BE96-A45CABC64F8E} with the Router Manager for the IP protocol. The following error occurred: Cannot complete this function.

Unable to add the interface {727D273F-CD9E-4DE7-BC90-985A618C7938} with the Router Manager for the IPV6 protocol. The following error occurred: Cannot complete this function.

Unable to add the interface Internal with the Router Manager for the IPV6 protocol. The following error occurred: The parameter is incorrect.

Any idea what I am doing wrong here?
