SYMPTOMS
When you try to set the Maximum Ports value of the PPTP WAN Miniport device to zero (0) through the Routing and Remote Access Service (RRAS) snap-in, you may receive the following error message:

PPTP does not allow the number of ports to be set to zero.



RESOLUTION
To resolve this problem, you must prevent either incoming or outgoing Point-to-Point Tunneling Protocol (PPTP) connections. To do so, follow the appropriate method:

To Prevent Incoming PPTP Connections

 * 1) In Routing and Remote Access Service, click the PLUS SIGN (+) to expand the node of the RRAS server.
 * 2) Right-click Ports, and then click Properties.
 * 3) Click to clear the Remote Access Connections (inbound only) check box.

To Prevent Incoming and Outgoing PPTP Connections
This method achieves the same result as setting the Maximum Ports value to zero.
 * 1) In Routing and Remote Access Service, click the PLUS SIGN (+) to expand the node of the RRAS server.
 * 2) Right-click Ports, and then click Properties.
 * 3) Click to clear the Remote Access Connections (inbound only) check box, and then click to clear the Demand-dial routing connections (inbound and outbound).
