Using DHCP with RRAS (MCP Series)

When Remote Access Service (RAS) uses Dynamic Host Configuration Protocol (DHCP) to obtain IP addresses for dial-in clients, only the IP address from the DHCP lease is passed to the RAS client. Other options in the DHCP scope are not.

RAS servers can obtain IP addresses for remote clients from a dynamic host configuration protocol (DHCP) server. DHCP servers provide static and dynamic IP address allocation on a large network. You should select this option if a DHCP server is available.

When the RAS server starts up with the option to Use DHCP to assign remote TCP/IP addresses, it makes several DHCP requests in advance and caches the DHCP leases that it will need for dial-in clients.

I’m running a Windows Server 2008 R2 test environment. The first error I encountered was: Error browing network: The list of servers for this workgroup is not currently available. Note: I kept the spelling mistake from the error message to make it easier to find via search engines. To get past this error, you have to enable and start the “Computer Browser” service. Then I started getting the error telling me that the Administrator is not logged on. That’s simply not true because I am logged onto another server (Name: ELARA): I turned the firewall OFF OFF OFF (It is a test network after all). I enabled Network Discovery and to do that I went on a service starting frenzy: DNS Client, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host, Computer Browser After all that, I ran the script against the se
