No ideas, just some more data. I had a call at home to say that a
regular user of VPN was setting up a new machine on the local network
and VPN didn't work, nor did his own laptop when he tried it. I had
recently connected from home using Win98, and did so again without
trouble. I tried it from an XP Pro machine at home and it didn't work,
several times. Back to Win98, OK. I tried from my son's XP Home, no
good, from Win98 still OK. I fired up W2K Server, no good. Tried it a
second time and it connected, though after a longer delay than usual.
Tried XP Pro, now OK. Called customer and they were now OK.
This must have happened after a reboot the day before, as the customer
had connected successfully the day before that. I'm not sure what, but
something got stuck somewhere and was cleared by the W2K connections.
Obviously this isn't happening for you, but I thought this case was
close enough to be another data point for someone. I had been thinking
along the lines of levels of encryption, which is lower from Win98, but
presumably W2K has the same level as XP. It was a few months ago, I
didn't think it was worth asking here as I had no information. Nothing
in any logs anywhere.
