Hello fellow members of AO. I'm currently having a promblem with a

clients PC. The customers issue is her ISP software (Walmart connect)

is corrupted and gave her error messages as soon as she opened the

application and also, she wanted me to clean up the PC from spyware

trojans etc... and wanted me to add more memory (256mb) aswell as fix

the dial up modem Promblem. Now I have the PC which is a HP Pavilion

305 series running Windows XP. I have installed the memory total now

is 352 mb of ram. I disabled use-less services on the PC aswell as did

all the updates for the PC. The system was running very sluggish

before because it was infected by a lot of different spyware, porn

dialers, trojans, found over 4 trojans, 6 porn dialers, and 400 pieces

of different spyware from cool websearch to 180 search assist, safe to

say all that is fixed. I called the client got her ISP info username

and password dial up access numbers and authentication phrase, I

deleted all the ISP software she had and manually built her a dialer

using "ICWCONN1" into the run field on the start menu, built the

dialer configured the dialer. Went to connect got error code 678. So I

used AT&F+MS=V90 into the extra iniziation settings under the advanced

tab in the modem properties. Which forces v.90 protocol since it was a

V.92 modem lucent win modem firmware version 8.28 updated Re-connect

this time I got error code 691. Very good now I know my authentication

is in-correct thinking simple fix "Invalid Username or Password on the

Domain", no promblem so I take out the username and password manually

type it in, still got same error code, next i called the ISP to verify

that the username and password was correct it was everything has to be

lower case (case senitive) we changed the password waitied 5 minutes

to reset on the server side, re-connect got error code 691.

Heres everything I did to attempt to fix this issue 691.

I reset TCP/IP stack by using "netsh int ip reset resetlog.txt" cold booted the PC.

Next I unchecked enable software compression, unchecked enable LCP extensions removed the check mark from Use IP header compression reconnect got error code 691.

Next I changed the modem settings by changing the port speed to 38,400 clicked on the advanced tab changed the INI string to AT&F+MS=V34 to force V.34 protocol. Next I hit the button below change default preferences button, made sure 38,400 was listed it was.

I changed data protocol to disable.
I changed the compression to disable
I changed the flow control to none

Re-connected got error code 691. Checked network properties it has client for Microsoft networks, TCP/IP checked and QOS Packet scheduler . I deleted and rebuild the dialers a couple times, got online with my ADSL connection went to www.walmart.com and downloaded her ISP software still got same issue going through ISP software (GUI) 691. At this point I need some assistance I searched Microsoft knowledge base for 691. Its the servers not authenticating the username and password if I can get past that point I'm online. PS there ISP doesnt have technical support, it does you have to pay 2.00 a minute for it. Anyone help? All help is greatly appreciated.
