Is the XP version pre-sp2? Here is my guess. If you could get to the WUD and do the updates your problem maybe solved by the updating to sp2. I think you could be having driver/modem software mismatch with your OS version causing a connection error. The modem software may have been patched to work with sp2 (did you update the modem software or does Verizon do it automatically?) and because you can't update you have sp1 which maybe crashing your connection.

No offense intended, it's just so many people post without doing some digging first. I took it for granted that you fell in that group. Sorry. You may want to post what you have tried and why just so you can check it off and not try the same steps again, Good luck.

What you done so far:

Your computer was having problems.

You formatted the drive and re-installed Windows XP (sp2).

After the format and re-install of XP all was well with the computer but you could not connect to the Internet.

When trying to connect to Internet you got the dun error 691.

You have worked through the KB 310431.

You then checked and tested your password and user name on another computer, where it worked fine.

When you tested the password and user name on another computer you used your cell to make the connection there by testing it as well and it worked fine.

You have tried uninstalling/reinstalling the modem. Not sure what you mean. Does your computer have an internal modem that you connect to your cell phone that you are physically plugging and unplugging, or do you have a cellular modem device supplied by Verizon that you are physically plugging and unplugging when you say ?You have tried uninstalling/reinstalling?? Do you hear the old dun noise or is it just get only the error code? Can you use your computer as a phone? If so, do you get a dial tone? All these questions are leading to, could you just have a bad jack/connection point on your computer causing this problem? Also, I once was having a problem with a dun that turned out to be a bad key on the keyboard. I typed in the password correctly but the bad key messed it up so I could not get the connection to work and I could not see the password was being typed in wrong because of those stars that come up as you type passwords. I was just suggesting these 2 items (bad jack, bad key) because you said you tried everything and so I offer them as possible things that might have been overlooked due to their nature.

Is it possible that your computer has an IP address that is incorrect and needs to be released and then renewed? If it is a cellular modem device supplied by Verizon can you call their tech support? Tech support always seems to want to cycle the IP addresses.

That is all I have, sorry I can?t think of anything else, hope it helps.

You hit the nail....

Thanks for the post! Luckily I only had to dig for about 10 minutes 'til I found this thread. I had just reinstalled XP and done all the recommended updates manually. Strangely, It did not include the SP2 update in the list. I had to activate automatic updates and give it a couple of hours before it did the deed. After the restart my speeds were back to normal. Note: the Verizon "tech support" people have still not responded after I wasted a couple of hours trying to get past their first tier "help"...maybe they should all have cnet accounts! ;-p

Will Verizon allow you to create a DUN (dial up network) or do you have to use their software to connect?

Better than even chance you will have to install the software provided by Verizon.

If you are getting this error Message:

"Error 691: Access was denied because the username and/or password was invalid on the domain"

Then you must install an application from Verizon or your Cell phone.

Cell connect error: 691

In reply to: cell connect

I take it you are getting the "username and/or password was invalid on the domain" error message.

If so then contact Verizon and your cell phone service provider to see if they have changed the rules on Internet connectivity via cell phone.

Your other system that still connects may be "grandfathered in" and not need/require any additional software. Don't really know..

Only that when I see this error Message "username and/or password was invalid on the domain", with a correct username/password I need to install the ISPs application.

verizon software
by squish72 / September 4, 2007 8:36 AM PDT

yeah i was wondering if verizon changed something untill i used my phone on a different pc (i installed the same drivers i have on my pc and used the same login/password) and it worked fine i think maybe something in my registry is messed up or something i dont know and i dont have another pc at my house to check side by side registry's ive never ever had a problem this long and not been able to fix it i'm just lost!!!!!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
