SYMPTOMS

When you double-click the Devices icon in Control Panel, you may receive the following error message:

Configuration Manager: This routine is not implemented in this version of the operating system.

Also, when you double-click the Modem icon in Control Panel, Modems Properties may not open.

CAUSE

This error can occur if the following Windows NT files have been replaced by Microsoft Windows 95 versions of the same files:

   %systemroot%\system32\Cfgmgr32.dll
   %systemroot%\system32\Setupapi.dll

These files may have been replaced by the installation of a program. If you receive the error message listed above, check these files to make sure they are the Windows NT versions.

RESOLUTION

Delete the existing files, and replace them with files from the Windows NT CD-ROM.

NOTE: Both files on the Windows NT CD-ROM are compressed and must be expanded. You can expand the files by typing the following commands at a command prompt (assuming that the CD-ROM drive is drive D, you are using the Intel platform, and the Windows NT installation folder is C:\Winnt):

expand d:\i386\cfgmgr32.dl_ c:\winnt\system32\cfgmgr32.dll
expand d:\i386\setupapi.dl_ c:\winnt\system32\setupapi.dll
