That reference seems to relate to Win95; step 1 "click on My Computer" is not useful; this problem is only in Win2K - my win98SE is fine. However, right click on modem icon (via control panel / network) for Properties, there is a tab "Networking" (Server Types is not available anywhere). Fiddling around more, i see server type is PPP (good); elsewhere there are 3 tick boxes one being "Enable Software Compression"; unchecking the other 2 makes *zero* difference (not good). TCP/IP settings are totally un-available (hyperspace?).
** The article may be useable and helpful for Win98/Win98SE but is of no help for Win2K. I have already been thru everything about 4 times so far; i do not mind doing it again 3 or so more times if there is a possibility of solving the problem.
