Modem Dial-Up Disconnect Problem

We have a modem dial-up connection to an external customer that remains stuck

in the 'disconnecting' state after a dial-up session. To get around this I

created a second connection to the same number which is fine until I attempt

to disconnect that new connection - it then goes into the disconnecting

'state' and the original connection then reverts to the good 'disconnected'

state. Our automated apps depend on a named dial-up connection so right now

I'm doing a lot of connection

renaming just to keep the apps happy. Any ideas on what the problem may be and

also how do you purge dial-ups that are in the disconnecting state (if

possible)?

BTW - This connection worked fine until 10 days ago. Thanks.
