I have the following network configuration:
SERVER_A: SBS 2008
Services: DNS, AD, File Sharing
SERVER_B: Server 2003
Services: DNS, AD, RRAS, DHCP
The router on the network forwards to SERVER_B for RRAS (PPTP)
When clients connect, they get an IP Address and DNS servers and they can connect to SERVER_A most of the time, sometimes it doesn't let them connect and says "Can't find server". Then we use the IP Address and it works OK.
One of the issues is the sporadic nature of this. Sometimes it works, sometimes it doesn't. I have DHCP set up to give out DNS #1 as SERVER_B and DNS #2 as SERVER_A. It's that way because if it's switched around, then they can't access anything on the office network. It's as if SERVER_A (SBS) is not responding to DNS requests.
I've changed settings a number of times, switch RRAS and all services to the SBS server like they should be but the clients connect and can't see any network services. It's almost like the server is not responding to any DNS requests for the VPN.
Any thoughts? I know it sounds garbled. I will clarify for you what I can.
