Question : Problem: Can I retrieve an old IP address

Folks,
A PC with a Failed hard  drive arrived into my desk yesetrday. I got the info from the hard drive itself but as my company uses STATIC IP address is there any other way retrieving the IP address from a file. I have heard something that you can retrieve the ip address from the C:\windows\system32\config\system file. How can I open this file if it ppossible at all.

Answer : Problem: Can I retrieve an old IP address

• Start regedit 
• select HKEY_LOCAL_MACHINE 
• In menu, select Load 
• choose that system file 
• enter a arbitrary name for the imported registry 
• browse the new key to System\ControlSet001\Services\Tcpip\Interfaces 

There are subkeys for each virtual or physical network interface, just visit them all, and look for the value of IPAdress
