Here's the scenario. We have an office located behind an ISA2000 firewall.
From this office we can VPN to a remote location via W2K, but not from XP
Pro. If I'm outside the office I can VPN from an XP Pro.
I ran Ethereal packet sniffer when trying to connect, and saw that there
were some checksum errors.
Is there an issue with XP Pro VPNs as opposed to W2K VPNs. Why does the W2K
work, but not the XP Pro from behind the same firewall?
Also, the XP Pro firewall is not running.

Thanks in advance
Mike
