PPTP Protocol Not Available on MCA Computers (168064)

The information in this article applies to:

Microsoft Windows NT Server 4.0

This article was previously published under Q168064

SYMPTOMS

When you try to install point to point tunneling protocol (PPTP), it does not appear as an installable protocol in the Network Control Panel on Microchannel computers.

CAUSE

Windows NT operating system components can be installed based on bus type. In this case, MCA is not listed as a supported bus architecture in the [PlatformsSupported] section of Oemnxppp.inf.

WORKAROUND

To work around this problem open the Oemnxppp.inf file (located in the %Systemroot%\System32 directory). In the [PlatformsSupported] section, add MCA. Another resolution is to delete the [PlatformsSupported] section entirely.

See Example:

Before:

   [PlatformsSupported]
   ISA
   EISA
   "JAZZ-INTERNAL BUS"

After:

   [PlatformsSupported]
   MCA
   ISA
   EISA
   "JAZZ-INTERNAL BUS"

STATUS

Microsoft has confirmed this to be a problem in Windows NT Server version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
