Point-to-Point Tunneling Protocol

(communications, protocol)
(PPTP) A tunneling protocol for connecting Windows NT clients and servers over Remote Access Services (RAS). PPTP can be used to create a Virtual Private Network between computers running NT. It is an extension of PPP sponsored by Microsoft.

Microsoft Point to Point Encryption may be used with PPTP to provide an encrypted connection but PPTP itself does not use encryption.

Compare: Layer Two Tunneling Protocol.
