Cisco Dialing to a Win2K server

Currently, I am configuring a Cisco router (1720) to dial out to a Win2K server, but the authentication doesn't seems to go through. I've tried both CHAP and PAP, but it failed. Win2K Server is enabled with Routing and Remote access and the users are grant permisions to dial in.

Is there anything needed to be done on the WIn2K server or the Cisco router ?

Thanks.

Irmoore,

Below is the cisco config.
BTW, I found out that Win2K only supports MSCHAP ano not PAP/CHAP, is that true ?

Are you using an analog modem connected to the serial 0 interface?

What phone number are you trying to dial?

You might want to read this and see if it helps:

You might need a chat script also:

Irmoore,

I am performing a test internally, I can dial out but the Win2K server authentication is not successful.


Thanks.

On the router, turn on debug ppp negotiation and look for any clues as to why it won't authenticate. Is the server in the 10.10.10.x network? The server should be able to authenticate pap,chap, or mschap. Your router should be also capable.
Add this line to the serial 0 config:
 ppp authentication chap ms-chap

Change this line:
 ppp pap sent username ...
to
 ppp chap sent username mars pass mars
 ppp ms-chap sent username mars pass mars

Does the username mars account have dial-in priveleges on the server enabled?

To continue with the last comment from Irmoore, Is Windows 2000 a domain controller and if so, is the domain in Native Mode? If it's in Native Mode, the dial-in properties will be used from Group Policy, you'll have to enable the dial-in properties using Group Policy (or you can change it on the user account to "allow access").

Where did you find out that "Win2K only supports MSCHAP ano not PAP/CHAP." I believe it supports PAP, CHAP, MS-CHAP, MS-CHAP v2, SPAP and EAP.

Where does that account exist, local on the Windows 2K server or in Active Directory?
