The Windows VPN is PPTP, so you're looking for a PPTP client on Ubuntu - fortunately one is built in.
This guide is slightly thin on details but should be relevant. This forum thread also looks relevant. The summary seems to be (and I haven't done this so I can't confirm it):
- Left click on the network manager and select vpn-> configure vpn .
- Add the credentials of your network.
- Click on advanced settings, select point-to-point encryption (MPPE) and ‘Allow stateful encryption’.
- Uncheck the rest of the options and save the settings.
