[vexxar]

Ok first of all, thanks for all your responces in advance. Now lets get down to the problem!! I have a lan connection and when i connect it to my laptop, it tries to identify in the begining and then says "unidentified network, no network access", and when i ran up windows Diagnostics, it says "Local area connection does not have a valid IP configiration".

Additional information: * I dont have bonjour or anything to do with apple installed.
*My firewall is off and i uninstalled macfee security.
*Laptop model: Dell inspiron 1501.

Iam really getting fed up with this, seeing that i have some really important documents i have to send via the internet and this problem happening suddenly, im really upset, please help me

Try each one by itself and test connection after each one.
Open cmd line.. (window key + R) in that window type cmd and hit enter
ipconfig /release
ipconfig /renew
ipconfig /flushdns

you an also try to disable your network adapter by going to control panel<network and sharing< change adapter setting(on far left panel) right click on your lan and pick Disable...... then power cycle your modem and router(if you have both) after they boot up all the way go back and enable you lan adapter and try your connection( you may have to restart after everything)
