I have a user in my work environment running PLC programming and he is requesting he need a local admin privellege for running that program and therefor he need local admin access with his domain user name. I was speaking to his Manager and told him that usually application doesn't need admin privellege. The worst case his program may be defined in a way that he need write access to certain file in system32 or any windows folder which may require access. His manager is worst than him for explanation. He is fighting that this person need admin access. By IT policy i didn't provide any local admin to any one and it doesn't make sense to me for my knowldge. There are two admin privelleges one is local admin and other one domain admin. I am the one has domain admin login. I want to know how the security could effect if the domain user is member of local admin. Please explain. Thanks in advance.
