Please refer to my earlier reply regarding reasons why VNC might exhibit
problems while other network applications might not.
As I previous suggested, the problem sounds to be with your router or modem.
Have you checked the Application Event Log on the server computer, for
messages indicating why the server closed the connection?
If your computer's physical network connection is physically damaged such
that it appears to by physicall disconnected every so often, then you may
well see Windows' TCP stack closing connections. If this were the case then
you'd frequently see the "Local Connection Connected" message pop-up from
the task bar.
It sounds to me, though, like either the router or the cable modem is
partially crashing, and is then re-setting itself. For web browsing and
other network applications that don't require network connections to be held
open for prolonged periods, this will have little effect, if any. For
long-term connections such as VNC, this will cause them to disconnect at
seemingly random intervals.
