How to edit Windows host file

[jawadtld]

Hi,

I want to edit windows host file located in C:\Windows\System32\drivers\etc\host .But it shows permission error when I'm trying to do this. I tried with running as administrator also. Still I can edit networks file located in the same folder (C:\Windows\System32\drivers\etc\networks) with same security permissions as of host file . I can edit the host file by opening it in the notepad as administrator. Is there any other method to edit the host file using LabVIEW.

Start your LabVIEW EXE as admin to have elevated access permissions...

Thanks for the reply. Already tried as administrator. But no use.

Have you tried changing the permissions on the file itself?

Microsoft is generally against having applications running as users modify important system files and/or do things like edit the registry.

I can edit another file with same security permissions and in the same location. For the host file it shows error even after giving full permission.

Like I said - Microsoft is generally against having pieces of software make modifications to important system files. It might be that the hosts file has special permissions since it can be used to override DNS settings and send users network/data to the wrong destination - you can surely imagine the number of viruses/trojan horses/phishing/scams that would take advantage of such functionality.

At last, I got a .bat file to add an entry in windows host file. Then run using the systemExec.vi. Now my code works exactly as it finds the server IP and adding it in the host file.
