Corporate IPv4 properties greyed out.

Hi, I would like to request for troubleshooting tips on a corporate computer ipv4 properties greyed out issue.

Here is the laptop issue.

if the computer is running in normal login mode either by the user or administrator, the ipv4 properties connection for lan is greyed out. It says it needs to install a protocol.

But, if i run it in safemode, the ipv4 properties for Lan connection is ok again.

I had already perform the following steps such as:

Solution 1:
(not working)

Type Cmd in the Start Search text box.
Press Ctrl-Shift-Enter keyboard shortcut to run a Command Prompt as an Administrator. Allow elevation.
Type netsh winsock reset in the Command Prompt , and then press the Enter key.
Do the same process for refreshing the TCP/IP just replace the typed command with.
netsh interface ipv4 reset press Enter
netsh interface ipv6 reset press Enter
ipconfig /flushdns press Enter
Restart your Computer.

(solution 2)
Not working as well

I had try to replace the corrupted tcpip.sys file in system32 with a working file “tcpip.sys” file in
c:\windows\system32\drivers\tcpip.sys

But then it comes out an error which says I doesn't have administrator rights to it eventhough I log in as administrator and I am in safemode. I try to change the sharing/ permission security but then it's all tick and greyed out except the special permission. But I saw that the only user who had allow editing to the windows file is the trusted installer.

I wasn't able to repair the OS as well because i am using a windows image disk that would require an os reinstallation through the server from another country.

Please advice me is there's is a solution to fix this issue. this computer is running windows 7.

I will look forward to your reply.

Thanks:D
