1. Explain hosts and LM hosts file?
The "HOSTS" file contains entries that simulate "A" records in DNS (and PTR records, too). Only DNS-legal names are allowed in this file.
The "LMHOSTS" file contains entries that simulate NetBIOS name resolution responses (and they have a baroque little mini-language to let you preload entries into the NetBIOS name resolution cache, specify domain entries, and include other files). Only NetBIOS-legal names are allowed in this file.

I will reboot my machine 3 times. If the problem continues, the 4th time, I will press f2 to enter the setup which will automatically make my machine go through a process called bios. The bios process will read all my hardware and take me to a configuration setup, then I will go on the boot tab or press F12/F8(depending on the computer) and start windows normally. IF THIS DOESNT SOLVE THE ISSUE, then I will reboot my machine, press F12 and enter the safe mode. Once I enter the safe mode, I will type "msconfig" and click on the "startup" then I will click "DISSABLE ALL >Ok>APPLY>RESTART.
IF SAFE MODE DOESN'T WORK:
I will insert the system recovery CD and press F8 or F12. Then I will press "R" for repair, and restore the system.
IF SYSTEM REPAIR DOESNT WORK:
Reinstall
LAST STEP, IF NOTHING WORKS:
Create a ticket for the client and transfer to tier 2.
