Windows 2008: CRM Server Problem - No internet connection after electrical failure shutdown

Case: CRM Server - Cannot remote & No internet connection after electrical failure shutdown

Study case:

One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become damaged or corrupted. If you cannot connect to the Internet and you have tried all other methods to resolve the problem, TCP/IP might be causing it.

Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state by using the NetShell utility (netsh).

Recommended solutions:

1. Logged on to the computer as an administrator. 
2. Type cmd in the Start Search 
3. Type netsh winsock reset at the command prompt, and then press ENTER.
4. > netsh winsock reset
5. *Note If the command is typed incorrectly, you will receive an error message. Type the command again. When the command is completed successfully, a confirmation appears, followed by a new command prompt. Then, go to step 3. 
6. Type exit, and then press ENTER.
