IAS/RRAS

[Gary Davidson]

Hi All,

IAS (Radius) is pretty new to me but heres are scenario and problem.

I've built up a Windows 2003 server and installed IAS, the server
hastwo NIC's, one internal one external and within the policies of IAS
no external traffic is permitted onto the internal network.

I have a large number of sites that dial into site every night. They
dial into a 3COM RAS 1500 (I don't have a password to get into this
but it has worked in the past) which communicates with my win2k3
server. Eventually the dial in connection is lost, error - Incorrect
Username or password.

I have created an account for the user id, it has dial in permission,
the server is a member of RAS and IAS group. I have captured the
network traffic and seen errors regarding unknown port UDP 2050
between the 3com box and win2k3 server. I have left the radius ports
at default. I can see that the user id is being supplied to the
server. I know the shared secret is ok.

Also when I try and configure RRAS on the win2k3 server it tells me
that the ICF service is running and should be disabled - IT is, but I
can't configure RRAS. It says its started but unconfigured yet I
can't do anything with it. Does this need to e configured and if so
how do I get around it?

Any help and enlightenment would be great.

Thanks

Gary

Disable the Firewall on the RRAS Server and diable the configuration on the
RRAS Server. Re configure again from scratch.
