The information in this article applies to:
This article was previously published under Q142543
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, you should first make a backup copy of the
registry files (System.dat and User.dat). Both are hidden files in the
Windows folder.
SYMPTOMS
When you start your computer, you may receive the following error
message:
Windows protection error. You need to restart your computer.
CAUSE
This error can occur if IP routing is enabled. IP routing is not a
supported feature of Windows 95.
RESOLUTION
NOTE: For information about how to edit the registry, view the Changing
Keys And Values online Help topic in Registry Editor (Regedit.exe). Note
that you should make a backup copy of the registry files (System.dat and
User.dat) before you edit the registry.
WARNING: Using Registry Editor incorrectly can cause serious problems
that may require you to reinstall Windows 95. Microsoft cannot guarantee
that problems resulting from the incorrect use of Registry Editor can be
solved. Use Registry Editor at your own risk.
Use Registry Editor to remove the EnableRouting value from the following
registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP
Also, remove the "EnableRouting=1" entry if it is present in the [MSTCP]
section of the System.ini file.
MORE INFORMATION
This problem is likely to occur if you upgraded a Microsoft Windows for
Workgroups-based computer using the Microsoft TCP/IP-32 protocol with IP
routing enabled to Windows 95. In this situation, the "EnableRouting=1"
entry is present in the System.ini file and is copied to the registry
during the upgrade process.
IP routing is not enabled by default in Windows 95, and can be enabled
only by adding the unsupported EnableRouting value to the registry.
