Dual Network Cards - Must Only Connect to One Network At A Time

[LEEDS]

Hi everyone
Hoping someone can give me a bit of advice.
Here's the scenario:
Company network - pc connected to the network
Additional server installed and configured on a separate network - users can get access via their desk ports - but only with another pc

I want to get rid of the extra pc by installing 2 network cards into one pc so that users can connect to both networks (each users desk will have ports connected to the new network - the 2 cards will have a standard RJ45 network cable in each connected to their respective networks)
The rule is that the users pc cannot be connected to both networks at the same time.So...with this in mind
Is there any way of allowing the user to "bridge" networks - ie; a user can be connected to the company network, then when required, drop or disable the company network connection and connect on to the new network via the 2nd network card - within one instance of XP pro?


Apologies if I haven't made myself clear
Thanks in advance for your help

If you really only need access to one network at a time, this will do the trick with only one network card:- http://www.download.com/IpManager/30...4-8690620.html
