Open the note pad. (You have to run it as Administrator). Then open C:\Windows\System32\ drivers\etc\hosts" file in the Note pad [i assume your windows partission is 'C' ;)]. Add the ip address and the host name at the end of the file. The IP address should be placed in the first column followed by the corresponding host name.
Ex:
192.168.0.24 sec.office.hms
Save the file and close it.
That's all.
