I know this is not completely *nix related but I hope someone has come across this issue. I have a user on our openVPN connection that is getting this error:

write UDPv4: The requested address is not valid in its context. (code=10049)

They are on a windows XP Home edition compaq laptop.

This is the only user that is having issues and I have determined that it is not a Windows problem. I have multiple Home and Pro XP users that all work.
I'm beginning to believe that it is a compaq software or hardware is but I am open to suggestions.

Hi! Sounds like a software conflict. The windows box might have a firewall installed.. That's only a guess though..
