I have a Cisco 2851 Router with an 8-port modem interface card. In addition to our Internet VPN, we had to have dial-up capabilities for some of our remote users who do not have the Internet. Until yesterday, this dial-up connection was unsecured and just simply dial-in to it would all you full access to our network.
Once I discovered this, i setup the connection to authenticate with our radius server on the AD. Now when a remote user attempts to use the dial-up to transmit data back to the main office they get the following error - "Interface is connected and hence cannot be deleted".
I did some research on the Internet and found on the MS site this is error code 908 (http://support.microsoft.com/kb/824864
). The problem is I cannot find any steps or ideas for resolution to this problem. If you can point me in the right direction or provide any assistance I would appreciate it.
