I've setup a Windows Server 2012 R2 Essentials DC. It was working fine in my test environment but I'm having trouble getting it setup at my clients. Here is their environment:
ISP modem connected to Netgear R600 which is acting as a DHCP server.
Router IP: 192.168.1.1
DHCP Range: 192.168.1.2 - 192.168.1.254
Server is a Dell PowerEdge T320 running Active Directory Services, DNS, RRAS.
When the server boots up it accesses the network but within minutes it loses internet connectivity and whenever I ping ANYTHING including the servers IP address I get "general failure". I've tried this with both an unused static IP as well as a dynamically assigned address.
I suspect there is a service loading on a delayed start - probably RRAS - that might be causing an issue, but the fact that I cannot ping the local IP address has me stumped.
