When you browse to a folder shared on a Windows machine on a network, you may need permissions to access it. A dialog box appears and request a username and password. If you enter one that doesnâ€™t work, you wonâ€™t get the chance to change it the next time you try opening that folder. There are no options in the Windows GUI to change the login information for a network share.
In order to change a user that is logged into a network folder, you need to use the net use command. The first thing that you do is disconnect from the share, which is done with the following command:
net use \\share /d
This deletes the share being accessed by your computer. Now you can connect to the share with a different user with following command:
net use \\share\folder password /user:account
where the password is the actual password used by account to log into the shared folder. The account name is a valid Windows user on the machine that your trying to browse to.
With these commands, you can connect to a network share with credentials other than what you logged into your Windows computer as.
