Cisco VPN client and Nortel VPN client issue

Used to have a configuration that works in Windows XP with Cisco VPN client version 4.8 and also Nortel VPN client version 5.

Now some of our customer have upgraded to new Nortel VPN version, and the client version would need to be upgraded too.

Recently we installed Nortel VPN client version 8 into the Windows XP machine and poooooof, Cisco VPN client failed to work - with the reason like unable to initialize the virtual adapter.

I am trying to think of the best way to keep 2 VPN client in one PC without further tweaking everytime they release a new version, right now I have a temporary workaround, that is to install 2 different Windows on top of my current Windows XP running on VMWare (VMWare Player is free) and install Cisco VPN client in one of the VMWare and Nortel VPN client in the other one.

The downside is that, we need to purchase 3 Windows license instead of one, perhaps Microsoft should release a Windows license for VMWare usage only.

And also, the time needed to boot all 3 machines up, it's not that bad, takes approximately 20 minutes.

Guess this is the safest and most future proof method for multiple VPN clients.
