ipconfig /release: An error occurred while releasing interface Loopback Pseudo-Interface 1

Today when I start and login into my laptop I have noticed that my laptop doesn't have Internet Access but it was connected with LAN network. Then I tried to disable and enable the LAN Network Adapter, now I am getting ip conflict message. So that I have decided to flushdns and release ip address. When I try to release IP by using ipconfig/release command, the following error occurs 'An error occurred while releasing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified.'
C:\>ipconfig /release

Windows IP Configuration
An error occurred while releasing interface Loopback Pseudo-Interface 1 : The sy
stem cannot find the file specified.

The operation failed as no adapter is in the state permissible for
this operation.
After I have analyzed some time, found the following recommended solutions

Steps taken to fix issue in my laptop (windows 7):

- Changed the machine IP manually into temporary IP address.
- Disable and Enabled LAN Network Adapter.
- I got the Internet Access through my LAN Network.
- Restarted the machine.
- Run the commands ipconfig/flushdns and ipconfig/release
- Now changed the IP manually to my original IP address.
