Netsh Winsock Reset to fix Windows Firewall error

[ZeDaX]

I tried to turn on Windows Firewall but I could not make it on and got this message "Windows cannot start the Windows Firewall/Internet Connection Sharing Service." With Event ID 7023. I tried to search information for fixing this error and came across 'Winsock Reset' process that can help to get rid of this error. But I wanted to know what this command does and is it safe to use this command?

Many Internet connectivity problems are caused by corrupt winsock settings. Windows sockets settings may become corrupted due to a networking software installation, such as spyware. A winsock reset restores Windows Socket settings to defaults, which may help to restore connectivity to the computer. To do a winsock reset in Windows XP, open a command prompt and type in: netsh winsock reset catalog
