This is a strange, yet possibly easy question for many of you to answer but it's driving me crazy that I can't figure it out.
I have two machines on a local LAN on a workgroup. I recently learned that you can use the shutdown command to remotely shutdown a computer if you have the administrator credentials. Being curious I tried to remotely shutdown the PC in the next room over and contrary of what I thought, I was able to shutdown the PC.
Now this confuses me because I should only be allowed to do this if I have administrator credentials of that remote PC; or in the case of a domain, domain admin. At first I thought maybe that if guest account is enabled and is able to shutdown it could facilitate the need of administrator credentials. I checked computer management and local group policy but everything related to guest account is disabled, except for what file sharing enables.
I am also not a member of the Administrator group on that computer so besides the file sharing thing I don't know what could be allowing me this access.
