Connecting to two networks simultaneously?

Hi There,

Just a quick question. I’m working in an office where I’m using a laptop with Windows 7. I connect to a company proxy server for all internet access with no problems. We also have an iOmega StorCenter hardrive which we use as a temporary storage server which is accessed wirelessly with a router configured or we can go in wired. Obviously whilst i’m working from that hardrive I’m not on the other network for emails etc and have to switch constantly.

Is there any way I could have the access to the hardrive via ethernet whilst still using the proxy wireless network for internet/emails simultaneously? This would help me out a great deal.

Many Thanks

Russell
