Dial-Up Networking Error 691

[hwpeder]

I have a problem I've not run across before. Customer brought his PC in with his modem not working. The modem dials in to the ISP, but receives this message:
"Dial-Up Networking Error: 691. The computer you're dialing into cannot establish a Dial-Up networking connection. Check your password and try again."

I have checked passwords several times. I've also tried to connect to a different ISP and get the same message. Changed out the modem, tried different slots to no avail. Tried all MS fixes with no relief. Did the ultimate: formatted hard drive and re-installed Windows. Still have the same results. PC seems fine otherwise, and the modem has been working for the past year. We installed it and it has been working fine. Still seems to be functioning, but will not connect to ISP's.

System is an Athlon 900 MHz with 128MB PC 133 SDRAM, 20 GB hard drive running Windows Me.

Any ideas? I am out of them totally.

TIA,

Howard

You've done pretty much everything I would but did you try a different modem as well? How about any other dialup account? Can it nework via any other means ie- NIC?

Greetings hwpeder,

Take a look at the following Microsoft Knowledge Base article.

Error 691: The Computer You Are Dialing in to Cannot Establish a Dial-Up Networking Connection

Yes Fink,

I tried another, brand new modem. Tried two different ISP accounts, same result.
Yes, it will connect to our cable connection here in the store via a NIC. I'm downloading Windows updates right now.

Thanks

ecross: I did take a look at that article and tried the fixes. I'm stumped!!

thx for the input

Just to be clear... you say you reformatted and reinstalled windows.. did you actually start from scratch and install a virgin OS setup or do it over top of itself. Sometimes the language can be a bit unclear about doing these things.

What I'm thinking is that if you installed the OS over top of itself some parts don't actually get touched, just checked and then ignored. Also have you tried completely uninstalling windows networking and reinstalling that? (although a virgin OS reinstall would have done that anyway)

[hwpeder]

yup Fink,

I fdisked the drive, formatted and did a clean install of Windows Me (twice). Still getting the same error. I also, removed and re-installed network components, TCP/IP, Dialup networking, etc. Doesn't seem like it, but could it be a hardware issue of some sort?

[fink]

I'm at a loss to figure out what it could be other than hardware. With a clean install and different modems, different locations/cables and ISP no's there's only one thing that points to and that would be the MB.

Do you have an old external dialup modem lying around you can try?

[hwpeder]

That's what I'm thinking, too. So, we'll see if the customer wants to spring for a new board. No, I don't have and external modem. Oh well, onward and upward.

Thanks for the help,
