1) First install vpnc:
sudo apt-get install vpnc
2) Download this deb I found in the Ubuntu forums for Edgy. You only need to download the second deb in the first post, as the first one installs network manager which is already in Bianca:
3) Extract and install the deb, and you should see an entry labeled "VPN Connections" when left-clicking on the network manager applet (Try rebooting if it doesn't show up right away).
4) Under VPN Connections select the option "Configure VPN" then click on "Add". You can now either manually enter the pertinent information or choose to import it via a .pcf file that your IT department may provide.
