After you connect to a PPTP server, you may not be able to transfer any data over the connection.


This issue can occur if all of the following statements are true:

  • The PPTP server is running Windows NT 4.0 Service Pack 5 or later.
  • The PPTP client is running Windows NT 4.0 Service Pack 4 or earlier.
  • The client password includes the German "Paragraph" sign (ANSI 167), also referenced as "Section Sign" symbol.
  • You are forcing data encryption over the connection.


To resolve this issue, upgrade the client computer to use Microsoft Windows NT 4.0 Service Pack 5 or later.

To work around this issue, change the password. Do not use the German "Paragraph" sign in your password.


Microsoft is researching this problem and will post more information in this article when the information becomes available.
