VPN Clients can't access other resources

I just setup RRAS to allow PPTP VPN connections and the clients connect fine
and can ping and DNS resolve the RRAS server but no other server or resource
in the network. Do I need to add a static route? All the clients are
receiving a 169. IP address too.

Thanks,

Luke

There is no way it will work if the clients are receiving APIPA addresses.
They are not routable.

It looks like your RRAS server can't get addresses from DHCP. Have you
tried using a static pool of addresses?

That's what I thought, but I set RRAS' DHCP to give out IP's in the same
subnet as the local network, and that still did not work. Any other Ideas?

That is not how it works. The DHCP option just means that the server
leases the addresses from DHCP and uses them as an address pool. If the
server can't do this for any reason you get APIPA addresses being used.

Configure a static pool of addresses in the same IP subnet as your LAN
machines. Use addresses from the high end on the scope like x.y.z.201 to
x.y.z.220 . You can reserve these in the DHCP scope if you are worried that
they might be issued to a LAN device

I can't believe I made that mistake. I've been searching for answers online
now how to fix this DNS problem, I can ping the IP addresses of internal
servers now but I can't resolve their name. Any ideas?

Just make sure that the client has the correct DNS address (ie the one on
the LAN you connect to). If it isn't getting it automatically, configure it
manually in the client's connection properties. If you can resolve a name
using theFQDN but not by just using a single name, manually code the domain
suffix into the client as well.
