Use NT Workstation as PPTP server?

Hi

I have many small remote sites that have Nt workstations running as the LAN server, setup with public IPs. I’d like to use PPTP to connect from my admin office to remote sites so I can access the databases running on their LANs.
Can you configure NT workstation to act as a PPTP server?

So then I will be able to just establish the PPTP connection to the remote site once installed, and then map drives to it’s shares, that kind of thing?

thanks
