The following sections cover testing your PPTP connection and sample output.

PPTP Ping runs on Windows XP Professional, Windows 2000, Windows NT, and Windows 98, but not on Windows 95.

Example: Test PPTP Connectivity

For this example, assume there is a PPTP server on site A and a PPTP client on site B. You want to test PPTP connectivity between site A and site B.

To test PPTP connectivity between site A and site B

  1. Run Pptpsrv.exe on a computer on site A. This does not have to be the PPTP server.

  2. Run Pptpsrv.exe

  3. Run Pptpclnt.exe [ServerNameorIPaddress] on site B.

  4. Open command prompt

  5. When prompted by Pptpclnt.exe, type some text to send to Pptpsrv.exe, and then click Enter.

  6. You see the text received at the host running Pptpsrv.exe. You then see five GRE packets sent from Pptpclnt.exe and received at Pptpsrv.exe.

  7. Repeat steps 1-3, this time running Pptpsrv.exe on a host on site B and Pptpclnt.exe on a host on site A. These can, of course, be the same hosts you just used.

Sample output: server side 

pptpsrv

Now you must run pptpclnt.exe on remote machine
