So I've tried
Local Policies → Adding Tokens in Registry → Firewall Rules
and I didn't want to disable my antivirus. It turns out that the problem was syntax:
psexec \\192.168.1.7 -u USERNAMEhere -i -p Passwordhere "C:\Users\Username\Desktop\New Folder\x.bat"
It still returned an error 0, but it worked.
