Vince,
Connection freezes are usually associated with a poor network connection -
either the ISDN line is shared by many people and starts dropping lots of
packets, or it's actually got a high bit error rate and causes TCP to drop
them, or worse, to corrupt the protocol stream. When it's not frozen, what
is the VNC session like?
On your PC, it's hard to say - the most likely cause is broken network
config or network card at one of the ends. It could also be a misconfigured
or old VNC installation on the Win98 box, but that seems unlikely. Which
versions of VNC are the client and server running in the two situations?
VNC obviously doesn't take 15 seconds to respond normally, otherwise we'd
have noticed and fixed it... :) I use VNC between a 2K box and an XP box on
a 50/50 wired/wireless LAN and it outperforms RDP noticably for most things.
Cheers,
