# Network Driver Error 7212 Sharing a Drive in File Manager

Article ID: 115926

Article Last Modified on 10/14/2003

APPLIES TO

- Microsoft Windows for Workgroups 3.1
- Microsoft Windows for Workgroups 3.11

This article was previously published under Q115926

## SYMPTOMS

When you try to share a drive in File Manager, you receive the following error message:
Network Drivers Error 7212
When you receive this error, you are unable to set up any additional shared resources. However, you still have full network access, and other users can still access your previously shared resources. Also, if you remove a shared drive, you cannot set it up again as a shared drive.

## CAUSE

This error occurs when:

- Your password file is corrupted.
- You have deleted and re-created a shared network fax directory. After the error message occurs, Windows for Workgroups does not let you rename or delete the .PWL files from File Manager.
- You add a new hard disk drive and then attempt to share it, but the drive letter conflicts with a letter previously used for a network connection.

## RESOLUTION

Delete or rename the *.PWL files located in your Windows directory (SHARES.PWL and <username>.PWL). You should then be able to share additional directories.
NOTE: If you are using a personal certificate, you should export it before renaming your .pwl file. If you do not do so, it may be unavailable when you send e-mail. For more information, see the following article in the Microsoft Knowledge Base:

## MORE INFORMATION

Typing `net help 7212` at an MS-DOS command prompt in Windows for Workgroups 3.11 generates the following message:
Error 7212: The password-list file is already open.
