[LUG] OT - Weird WinXP Internet connection issues

 

Hi all,

Sorry for the Windows question on a Linux list, but I figure someone
here may be able to point out the obvious to me - I've been racking my
brains over this for several hours now.

On my Mum's XP PC she can't load up *any* webpages nor will most
applications actually make a successful outgoing connection.  I have
installed LogMeIn onto it so I can remotely help her. She has Skype
installed. Both of these run at startup.  Both of these are working
absolutely fine.

So, on the surface it would seem that everything is OK from a network
point of view - Skype and LogMeIn work brilliantly, and one can
successfully ping from her machine, through the NATed router to
anywhere on t'Internet.  Nslookuping works well too.  However, try to
establish an actual connection and it fails.

Any thoughts?
