Try out this…. To do this job, you must have admin privilege,
- Click Administrative Tools thru Start > Programs or thru Control Panel
- On left-hand side look for the Server Name (IIS version matters) and click + symbol
- Right-click on Domain name > Properties
- On Directory Security Tab search for “IP Address and Domain Name Restrictions” and then click Edit
Remember, there is 2 options, either grant access to all computers & restrict individual IP’s / vice-versa
Now, to make restrict IP, or to add an IP address, click Add and next I hope u may do it ur own by following the on-screen instructions.
Here is a Good Guidance. Though it is based on Windows 2008, but hope it gives some idea on the same.
