Dial-Up Connection?

I am working on Win2K Pro. Recently I installed a modem for a dial-up
connection to the Internet. To connect to the Net, I connect my
telephone to a USB port in my CPU. After successfully installing the
modem & creating a new dial-up connection, when I try to connect to the
Net (by opening the newly created connection & then clicking the "Dial"
button), I am first shown a message that says "Dialling XXXX" (XXXX is
the phone no.). This is followed by another message that says
"Verifying username and password". This is finally followed by the
message "Registering your computer on the network".

After this, I get an error message that says:

Error 720: The connection attempt failed because your computer and the
remote computer could not agree on PPP control protocols.

The service provider insists that there is some problem with the USB
port in my CPU to which I connected the cable from the telephone. Since
my knowledge on networking & hardware is highly limited (I am into
software programming), I had no option other than taking their word
that there must be some problem with the port though I pointed out to
them that had there really been some problem with the port in my CPU,
how would the username & password that I entered to connect to the Net
got verfied but as already pointed out, they insisted that there's some
problem with the port in my CPU only.

Now what I would like to know is had there indeed been some problem
with the USB port in my CPU, would the username & password got verified
successfully in the first place? In other words, shouldn't an error be
generated when the username & password were being verified if the
problem existed in the USB port?

Note that when I navigate to Start-->Settings-->Control Panel & open
"Phone And Modem Options" & go to the "Modems" tab, the "Modem" listed
is "LGE CDMA USB Modem" (which is the name of the modem I installed) &
it's corresponding "Attached To" value shows COM3 (which is the USB
port).

My mouse is also connected to another USB port. I removed it from there
& attached it to that USB port which the service provider engineers
were insisting was the cause of the above error message but the mouse
worked perfectly. So had the problem been with the USB port (that the
service provider engineers were pointing to), would the mouse have had
worked properly?

I might have asked very silly questions but to be honest, as already
pointed, my knowledge in networking & hardware is highly limited; so
please pardon me for the same.

Thanks,

Have you tried clearing the "Negotiate multi-link for single link
connections" check box in the Settings box on the Networking tab? I think
there is a KB article about this.

Sorry Louis but I couldn't exactly get you. I couldn't locate the
"Negotiate multi-link for single link connections" checkbox anywhere.
Could you please be a bit more specific? Also a link to the KB article
would be highly appreciated.

Moreover I would like to know whether the counter arguments I gave to
my service provider personnels (i.e. had there indeed been some problem
with the USB port in my CPU, the username & password wouldn't have got
verified successfully in the first place & secondly, had that USB port
been really defective, my mouse wouldn't have worked when I attached it
to that USB port which the service provider personnels were saying is
defective) are correct or not?

Thanks,

Right click your connection and choose "Properties', then on the
"Networking" tab there is a "Settings" button. On that screen are 3 options.
You may want to try disabling the "LCP Extensions" also. I am going from
memory here as it has bveen awhile since I encountered this problem.
