Potrebna mi je pomoc oko postavljanja lozinke na racunar kada se na njega pristupa sa LAN-a. Unaprijed hvala!

If the computer are in a Domain, you'll have to go to the company's Server (domain controller), click start, programs, admin tools, active directory users and computers. Select your domain users' group on the left pane and users will appear on the right. Here you can create new users and reset passwords.

Workgroup:
You'll need to log into the computer as Administrator, then control panel > admin tools, computer management, Local users and groups, select Users. On the right side you can create new users and reset passwords.

For this you'll need to log in as username: Administrator
and the password for this account.
If you don't have the administrator password for each machine, you can download a program called ERD Commander to reset passwords.

Nadam se da razumeš engleski, mrzelo me da prekucavam
