My company only has one server running Server 2008 Enterprise as a DC. Can i setup VPN on that server? If I can, what would be the disadvantages of doing so?

Hi, We don't suggest that a domain controller with more than one NIC and/or IP address, and/or RRAS installed on it (for VPN, routing, dialup, etc), or with a PPPoE adapter from your ISP's ADSL line, because multihomed DCs will cause numerous issues.
