For starters - I'm not an admin, I'm a programmer, so please give me basics when you feel it's necessary.
The background: At uni we decided with some friends and a PhD to write an application to aid teachers in their work. We have an VM with Windows Server 2008, I have administrative rights on it, and I've installed TFS 2010 and everything else we need (SQL Server 2008 + some tools). VS2010 connects flawlessly to the TFS server when we're on the local network, but does not when we're in home. I'm familiar with the use of VPN (which would help in our case), but I've never configured it. I have forced the domain administrator to let me use his account to set up the Windows Server VPN (the built-in one, by adding a role and then configuring everything in server manager) on the machine.
The problem: I have no clue how to connect to the virtual network from our private machines. We all have Windows 7 Pro or Ult. Is there any built-in VPN client? If not, can we use something like OpenVPN (I use it at work), or does it require server to be installed on the VM, and a separate configuration?
Too long : How to connect from a Win7Ult machine outside a LAN to a VPN configured on Windows Server 2008 machine (the built-in VPN, not any third party VPN server)?
Please don't send me to the network admin, he doesn't know a thing - that's why I had to configure the VPN.
I'm not good at that configuring stuff nor do I enjoy it, so if you could help me I would appreciate it greatly ;)
