Error 630 on 2nd Dial Up Connection (DUN)

[Simon Chapman]

On a first attempt to dial up to an ISP Internet Connection, the 3Com
Internal Modem will dial and connect with no issues. Collection of mail
and/or internet access is fine.

On disconnection to the internet, should another session be attempted when
the modem attempts to dial, an error code of 630 is shown and a message
saying no modem is installed or is available.

The machine then has to be restarted before another dial up connection can
be established.

Any help people can offer would be appreciated.

Regards

Hello, Simon,

For the 630 error, I suggest that you replace serial.vxd using either
Version Conflict Manager or System File Checker.

Both of these utilities are available by going to Start>Run and typing
"msinfo32" and then hitting <Enter>. When MSinfo opens, click on Tools for a
list of other programs, including Version Conflict Manager and System File
Checker.

While you are in Microsoft Information, you might also want to check for
hardware conflicts by expanding Hardware Resources and clicking on
Conflicts/Sharing.

Also, you might need to replace your telephon.ini file. Here is the KB
article that tells you how to rebuild it:

And, here are two more links that should provide some help:

I hope this helps you,
