Backups failing with Error: 2034 - FATAL cifs_cant_use_detail CIFS cannot connect to share (4039497)

"Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again." is a Windows error that you will usually find reported in Windows Event Viewer Application Log as a 1219 error.

This is usually due to a connection to the Repository share being stuck open.

Rebooting the vRanger server will resolve the issue but if this is not an option you can:

1. Open an administrative command prompt.
2. Type “net use“ and hit Enter.
3. Look for anything listed that is pointed at the repository.  Often it is a mapped drive.  This is the connection you will want to remove.
4. To remove the connection type “net use /delete \\server\folder” as you see the server\folder listed for the connection you would like to remove.
5. If the above command will not work, you can delete all current connections using “net use * /delete“.  CAUTION: The preceding command will remove all mapped drives as well.
6. Once this is done stop and start the vRanger services.
7. Retry the backup.
