It's about VPN client on Win2k. It keeps disconnecting after few minutes,
I've installed every single windows update available [to the public].
Speaking about public, KB 843357 confirms that it IS microsoft's fault to
have a flaw in their operating system but they don't support OEM OS, I got my
win2k w/ my toshiba laptop, and I have called toshiba but they said that only
microsoft can provide the hotfix.
This is getting too much frustrating, so if anybody - anybody at all - can
even response, I'd really appreciate it.
