how to disable auto login network share folders

Na google sm pogledu vendar sem našel tutoriale samo za xp in ne za windows 7(tega uporabljam na obeh računalnikih).
Zanima me samo kako spremenim ime za se prijavit v mapo katero delim na mreži, saj sm prvič se prijavil za napačnim računom in zdaj nimam dostopa do podatkov ki so na mojem drugem računu, ter ne vem kako se prijaviti z drugim računom.
Ker slabo razlagam vam dam to za prebrat:

I believe what the question / comment is that everytime when he accesses 192.168.1.2, it automatically opens. The first time, there was a prompt for the username and password. Now it never does that. How can he have it automatially ask for a username and password everytime. Not just the first.

Hvala!Prosim tutorial za windows 7 in ne xp.

Hvala!
