Re: VPN concentrator 3000, VPN client v5.0 on Win2k server/adv.
I've had issues like this before. It's usually a minor config issue. First, go through all the client settings and make sure they are exactly the same as on the XP machine - particularly the transport settings. If there is a firewall in between, it may be possible that TCP 10000 is not open so set it to whatever it is on the XP box.
Perhaps the Win2K server has a software firewall? If so, disable it for testing purposes.
Still not working? Might need to dig into it at the packet level - WireShark can be your friend - and it's free. Run it on the XP first so you can see what the packet exchange is supposed to look like then on the Win2K server - note the differences.
