  • KB450243 – Windows Clients Holding onto Past Network Share Credentials

Scope/Description

This article details the way to delete past mapped network  drive credentials in order to properly map the network drive.

Prerequisites

  • A Configured 45Drives unit
  • A dataset with a Samba share set up
  • Windows Client that you are trying to map the network to
  • “Network browsable” option selected on share options

Steps

  • When unable to map a browsable network samba share despite using the proper credentials, open the command prompt.
  • Entering “net use” will list all network shares. Shares without a Local drive name are not mapped, but have been browsed to and the credentials used to access them have been cached by Windows.

  • In this example, freesmb is an open share accessible to guests, while Benton is not.
  • After accessing freesmb and Benton through the network, we can see them populated in “net use.”
  • If we attempt to map Benton as a local drive with proper credentials, it will now fail and we’ll be met with a looping “Connecting to [IP address]”


 

 

 

 

  • To map this with proper credentials, we’ll need to use “net use \\192.168.16.87\Benton /delete”. If any other shares were browsed using the same IP/Host name, these will need to be deleted as well.

  • After deleting these shares from net use, we will be able to map the share properly.

Verification

We should now be able to browse to the other shares without issue as well. Browsable, unmapped shares may not appear under net use any longer as well.

 

Troubleshooting

  • If you’re still unable to map the SMB share properly, double check the credentials being used.
  • Check the permissions set on the dataset and parent pool.
  • Check that permissions are either set to inherited or not, adjust accordingly.
  • Review /var/log/samba/log.smbd for any error messages pertaining to Samba
  • Review /var/log/messages for any Samba errors
  • If network shares are no longer browsable, review the permission level the account used to map the share currently has.
