How to Resolve ERROR_SUBST_TO_JOIN 141 (0x8D)
The ERROR_SUBST_TO_JOIN 141 (0x8D) error indicates that the system attempted to use the SUBST command to assign a drive letter to a directory on a drive that has previously been joined through the NET USE command or a similar method.
This error occurs because mapping a drive letter to a directory that belongs to a network drive is not permitted. A simple solution to resolve this issue is to restart your computer to eliminate temporary problems and refresh the drive mappings.
How to Resolve ERROR_SUBST_TO_JOIN 141 (0x8D)
1. Verify Current Mappings
- Hit the Windows key, search for cmd, and select Run as administrator to open Command Prompt with elevated privileges.
- Input the command below to view all currently mapped drives and their statuses, then press Enter:
net use
- In the displayed list, check for the drive letter or directory that you attempted to use with the SUBST command; if it appears, that could be the source of the error.
2. Use an Alternative Drive Letter
- Press the Windows key, enter cmd in the search bar, and choose Run as administrator to access Command Prompt with elevated privileges.
- Type the following command to see the list of all currently mapped drives and their statuses, then hit Enter:
net use
- Pick a drive letter not listed, and execute the following command after substituting the desired drive letter and directory path before pressing Enter:
SUBST Z: "C:\Path\To\Your\Directory"
- To confirm the new mapping, re-enter the net use command.
- To access the newly mapped drive, press Windows + E to open File Explorer.
- Navigate to This PC, find the newly assigned drive letter, and double-click it to open the directory.
3. Eliminate Existing Mappings
- Press the Windows key, type cmd in the search box, and select Run as administrator to launch Command Prompt with elevated rights.
- Enter the following command to retrieve the list of all currently mapped drives and their statuses, then hit Enter:
net use
- Identify the drive you wish to disconnect, then execute this command after replacing [drive letter] with the appropriate letter to delete the mapping, and press Enter:
net use [drive letter] /delete
- Run the net use command again to verify that the mapping has been removed.
4. Assess Drive Status
- Press Windows + R to bring up the Run window.
- Input diskmgmt.msc and click OK to access the Disk Management interface.
- Find the drive and examine its status; possible statuses include:
- Healthy: The drive is functioning properly.
- Unallocated: Space that has not been partitioned.
- Offline: The system cannot recognize the drive.
- Foreign: A drive from another system that requires importation.
- You can also right-click on the drive, select Properties, and review detailed information about it.
In conclusion, resolving the ERROR_SUBST_TO_JOIN 141 (0x8D) can involve checking current mappings, assessing drive status, or removing existing mappings on your system.
