BleepingComputer.com: Service Network Location Awarness Error 1079

Hi,
this is my first post, i just arrived and therefore i would like to say HALLO to everybdy here !!

My problem> i got the following problem on my laptop HP 6720s under Vista Home basic edition (i have also installed the service pack 1).
I cannot connect to any netwrok (wireless or wired) because some services are not running and after investigation i realize that the problem starts on the service in subject. When i try to start it manuallu i get the error "1079: the account specified for this service is different by the account for other services running in the same process". Well, here my competences end. I do not know how to find the PROCESS related to this services, i went through the dependencies but this is no helping me.
Somebody can give me an hint ?

Thanks a lot

PS This service has Local Service as log on; if i try to run it as local system account i get anyway the same error.

On my system this service runs under the Network Service credentials - so running with any sort of Local credentials probably won't work.
Use the Logon tab for the service and specify "Network Service" (without the quotes) as the account that it should run under.

Thanks Usasma,
i have tried before with all the 5 user i have defined on my laptop but the situation doesn't change....the error remain the same.

Moreover, it ran till few days ago; i had a wireless connection in an airport and till i shutdown it in sleep mode it was fine. Only when i restored after my flight i got this error and at the beginning it was also coming with an error on firewall ("two or more firewall running...") therefore, after several test, i installed the Norton antivirus (i had a copy but i never used because i really do not like it) because not on HP laptop the security services sometimes requires this type of antivirus. Than, the problem on firewall disappeared. Any other suggestion ?

Thanks anyway....
