In PuTTY go to Connection/SSH/Tunnels
Source port: 1234
Destination: 1.2.3.4:22
Press Add

Connect to W2K as usual. Ignore its console.

Open a new PuTTY instance, but connect to 127.0.0.1 on port 1234
You will get a connection to the Linux server.

(Replace 1.2.3.4 with the hostname/ip of your Linux server, 1234 can be
changed to an arbitrary port)

I don't think you can completely skip the console allocation with
PuTTY.exe, but you can do it with plink:
 plink -N -L 1234:1.2.3.4:22 username at 5.6.7.8
(replace 5.6.7.8 with the hostname/ip of the W2K server)
