Nwrdr.sys Fails Reading File with Execute Only Attribute

   ... once assigned, this attribute cannot be removed.
				

MORE INFORMATION

The default behavior explained above can be altered to allow Nwrdr.sys to read Execute Only files. The fix and a new registry parameter are required. The following instructions explain how to enable this functionality:

WARNING: Using the Registry Editor incorrectly can cause serious, system- wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

1. Rename the existing Nwrdr.sys file in the %Systemroot%\System32\Drivers directory.
2. Copy the new Nwrdr.sys file to the same location.
3. Add the following registry values by running Regedt32.exe.
   
   In HKEY_LOCAL_MACHI on Local Machine:
   
   Key Name: SYSTEM\CurrentControlSet\Services\NwRdr\Parameters Name: ReadExecOnlyFiles Type: REG_DWORD Data: 0
4. Stop and restart Client Services for NetWare or Gateway Services for NetWare, depending on whether the fix is applied to Windows NT Workstation or Windows NT Server.

NOTE: Winfile.exe in Windows NT 3.51 and 4.0 will not display files with the X attribute. This was a pre-existing condition. The command prompt and Explorer.exe in Windows NT 4.0 will display files with the X attribute.
