How can I clear the "authentication cache" in Windows 7 to a password protected samba share?
How about this:
net session \\samba.server.ip.address /delete
You can also use:
net use
To give a list of active sessions and to ensure that you've deleted them afterwards.
Try this
Control Panel\All Control Panel Items\Credential Manager
Click on the arrow beside the cred you wish to delete
than click on remove from vault
