When you try to install the Windows NT Server Tools on a Windows NT Workstation-based computer, Setup may stop, and you may receive the following error message:

The process cannot access the file because it is being used by another process.

The Client-based Network Administration Tools were not correctly installed on the system. Check for sufficient disk space and correct access permissions on the Windows NT system drive, then retry the installation. Setup must be run from the directory where the Administration Tools reside."


This behavior can occur because the installation setup process has already been executed.


To resolve this issue, quit File Manager prior to running the installation of NT Server Tools.


File Manager is the user interface used to administer Macintosh Accessible Volumes. Installing the Server Tools on the Windows NT Workstation modifies File Manager to include the MacFile menu required to administer these volumes.

The Setup.bat file that accomplishes this is in the Clients\Srvtools\Winnt folder on the Windows NT Server CD-ROM and attempts to register a .dll file with Windows NT. If File Manager is running, this cannot be accomplished since either the .dll is in use or the registry is locked.

The following section of code that accomplishes this is taken from the Setup.bat file:

call %systemroot%\system32\sfmreg SMAddons sfmmgr.dll ntnet.ini > nul:
call %systemroot%\system32\sfmreg Addons sfmmgr.dll winfile.ini > nul:
goto Exit_SUCCESS

If Setup does not finish during an initial attempt to install the server tools, this article should not apply and the error is probably due to some other cause.
