How can I let non-admin users run a script as an admin to modify a file on a Network Share?

It sounds like you're trying to get non-admin users to run scripts that need elevated permissions. Just remember, with that approach, you're opening up a huge security risk. If someone finds the script, they could turn it into a backdoor for a Trojan or worse. Instead of trying to elevate user permissions through scripts, I suggest focusing on the underlying permissions of the file itself. Why not grant necessary access to the user group that needs to modify that file directly? It's safer and more straightforward.

Beyond what others have mentioned, I'd look into potential double hop issues. I tried nesting Invoke-Commands and passing in admin credentials, but like you, I faced access issues once again. It’s a tricky situation!

You might want to consider just granting the needed permissions on the Network Share instead. If you do that, users won't have to run a script for changes. It could save you a lot of hassle!

If you're really determined to make this work with a script, one wild option is to hardcode the admin username and password directly into your script block. Just keep in mind that's pretty risky! You'd be better off exploring security configurations instead.
