SYMPTOMS

When you start Windows NT 4.0, the system stops and displays the following message:
Stop: c0000135 {Unable to Locate DLL}
The dynamic link library FILE_NAME could not be found in the specified path Default Load Path.

CAUSE

This error can occur for any of the following reasons:

  • File_name.dll is missing from the %SystemRoot%\system32 directory.
  • Your computer is loading the Sermouse.sys file.
  • If File_Name.dll exists, the software hive may be corrupted and, therefore, cannot load.

RESOLUTION

The method for checking whether File_name.dll exists varies, depending on the file system in use.

For NTFS file systems, install a parallel copy of Windows NT into an unused directory, and then verify that File_name.dll exists in the %SystemRoot%\System32 directory.

For FAT File Systems, an MS-DOS installation disk can be used.

If the file exists, it is possible that the registry software hive has been corrupted. Check the integrity of the software hive by using the following procedure:

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

NOTE: In every case tested in which the software hive could not be loaded, the File_name was Winsrv.dll.

  1. From a parallel installation of Windows NT, click Start, and then click Run.
  2. In the dialog box, type Regedt32.
  3. On the toolbar for Registry Editor, click Window, and then click the window with the following name:
    HKEY_LOCAL_MACHINE ON LOCAL MACHI
  4. Select the HKEY_LOCAL_MACHINE key in the left pane of the window.
  5. On the menu bar, click Registry, and then click Load Hive.
  6. Browse to %SystemRoot%\System32\config, where %SystemRoot% is the correct installation of Windows NT that you want to check.
  7. Click the file named Software. In Windows NT 4.0, this will be the file named Software that does not have an extension, and has a generic Windows icon next to it, not the file with the Notepad icon. In Windows 3.51, the file name is System, has no extension, and has a generic Windows icon.
  8. The system will prompt for a key-name to use in loading the hive. You can type whatever you prefer in the dialogue box; Work would be a good choice.
  9. The hive is corrupted if you receive the following error message:
Registry Editor could not load the key. The file is not a valid Registry file.
After you have determined the problem, there are several ways to resolve it. The software hive can be restored by making a parallel installation from backup files. It can also be restored from the latest emergency repair disk (ERD), using the procedure outlined below.

Note: Windows NT 4.0 requires the Setupdd.sys file to be copied to disk 2 of the Windows NT Setup disks to perform this repair without a CD-ROM. This file can be found in Service Pack 2 or later.

  5. When prompted to do so, insert the emergency repair disk that was originally created for this computer, or press ESC to let Windows NT search for repair information for version 3.51 or version 4.0.
  6. Setup will then ask which registry files should be replaced. Using the arrow keys, move the cursor to Software (Software Information) and press ENTER. Next, move the cursor to Continue (Perform Selected Tasks) and press ENTER.
