I connected to a computer in our company LAN with an account (for example, user1). A login dialog appeared and asked me its username and password. Then, I checked a check box to remember the password. Though, I will log into this system using this user by default.
Now, I need to log into that system again. But this time, with another account. But no login dialog box appears for me.
What should I do ?

Any particular OS and protocol? – Ignacio Vazquez-Abrams Feb 5 '13 at 8:04
What do you mean by "connect"? Did you open it in the windows file explorer via "browse network"? – DaDaDom Feb 5 '13 at 8:04

I've turned a computer on. I tried to do something but it didn't work. It once worked. How can I make it work again? – artistoex Feb 5 '13 at 8:14
@artistoex If you are also having a issue I recommend you open your own question. You will need to provide much more details in your question as right now your statement is extremely generic. – Scott Chamberlain Feb 5 '13 at 8:24

Go to control panel -> credential manager, and remove the stored credentials from there. If it's not shown there.

on a command prompt shell:

  1. run command "net use" this will show list of network connections stored.

  2. from output of last command, run:
    net use /delete \\{network_machine_connection}

  3. try accessing machine after that.
