Ö÷Ìâ: Unable to sync .... weird problem
ÈÕÆÚ: 2003Äê11ÔÂ26ÈÕ 0:30

The modem is a Plusnet supplied Binatone DSL model.

The modem cannot sync with the exchange for more than a few moments at a
time, but not on it's own ... read on.

Somewhat oddly, when starting a standard DUN connection, the DSL modem
will sync with the exchange for just a few seconds, before going back to
"NO SIGNAL / TRAINING"

When Windows XP is just sitting idle though, the modem is always at a
"NO SIGNAL / TRAINING" state.

However, on trying the modem on a different computer (laptop) there was
full synchronisation, which i guess rules out a line fault.

I think that there is a connection (no pun intended) between the DUN
connection allowing the DSL connection to sync for a few seconds, and
that 'something, somewhere' in Windows XP is preventing the modem from
maintaining sync, or even getting there in the first place before a DUN
connection is initiated.

A previous install of Norton Personal Firewall was removed because it
was preventing internet access for some reason, and so i don't know if
this has damaged/corrupted those files which the DSL connection needs to
be able to sync?

Could it be a TCP/IP error of sorts, or maybe a winsock issue?

Mcafee anti-virus 7 was also installed on the machine (now removed to
try and eliminate it) which reported a change to winsock had been noted
after the modem was installed.

What files does XP use to sync the modem, as obviously it hasn't even
dialled into the ISP at this stage, so i can't see it being a TCP/IP
fault?

Could i (should i) try SFC.exe to see if that uncovers anything?
Could, would Mcafee/Norton have overwritten/changed/damaged any files
that would be need to sync the modem?

There are no firewalls in place.

If anyone can throw some help into the arena, it would be most
appreciated.

Or on Thurs, it's a format and reinstall .....
 
Just a thought; I had a similar problem on my Mac and it turned out to
be a piece of software continually scanning the USB port for another
device that was not connected. I used an application to view the
processes going on and hence track down the offending item. I very
nearly moved to an Ethernet router...

I realise that you are using a Windows system and hence I cannot
recommend any specific way of looking for the solution, although
doesn't system tools (or something similar) allow you to look at the
processes? (For reasons of health -no joke - I have not had to use my
work Win 2000 PC for about 16 months)

Good luck, Nick
