Richard,

SWAG. You don't have a firewall enabled on each machine, do you?

Explanation
The server could not establish a listening endpoint on the transport
listed in the event. The status code returned from the underlying
transport is in the Data box. This status code might explain why
this operation failed. The problem might be caused by one of the
following:

A lack of memory,
A malfunctioning network interface, or
A network device that became unavailable during startup.

Hi ... the 'client' to the gateway pc is totally shagged as far as
any internet access is
concerned - no matter which pc is the client. (I have only two, so
can only swap over client/gateway)

BUT .. if the client is given its own internet access (via a payg
dial-up) then all is well (apart from the slow modem speeds!). As
soon as the independent modem link is disconnected, then the client
is once again unable to find sites, use yahoo or windowsupdate etc..

I must stress that this problem effects WHICHEVER pc is the client.
Each time I swap the client/gateway over, after a brief period of
good internet access, the problem suddenly resurfaces on the client
pc.

The client also cannot access the list of drives/folders and printers
within the workgroup, and cannot create/map network drives/printers.
The gateway pc however can access its own networked items, but cannot
list those on the client pc. So I also cannot create on the client a
mapped network drive from the gateway (ie. can't create J: (on
client) = C: (on gateway).)

I have tried my best to follow the points in the various links you
gave. But none of them really matched what I am experiencing.
