internal IP Address of subnet mask of

all the client machine with a Static IP address of

Was this done on the RRAS service or the user account dial-in properties?

On mine i have set the Dial-In properties to grant access using remote acces policies,
then in RRAS set the remote access policy to enable access for a security group that user is a member of.
make certain that if you have multiple policies in RRAS they are in the correct order with the last one deny all.

how is your IP tab setup in the policy that grants vpn access under edit profile?
if you have the default setting of server setting default of server setting to user server setting and that is set to DHCP then you client systems are not getting an IP address. maybe use a static pool (RRAS server properties)

hope some of this helps
