Roger,
If you tried the same operation over a different portion of the network
(like the LAN), I bet you would have found the transfer was successful, and
if that is true, the MTU suggestion, may help! As I said, most often I see
these problems relating to dialup connections and those that have responded,
have indicated the MTU setting at the dialup routing device, did help. If
the users with problems, are _always_ your dialup users, that is another
clue that it is only this route that has the trouble.
Most Web Browsing sends much smaller files, so I'm not sure that tells us
much. The typical symptoms of MTU problems (in my experience) is that small
transfers work OK and there seems to be a certain amount of data that is a
'threshold' and once that is exceeded, things get bad, really fast.
Was your POP3 connection over the same dial up? If that was true, then I'm
not sure why it too would not be affected. Maybe the http adds more data to
the stream whereas POP3 adds little overhead and that extra data got you to
the 'threshold', sooner?
