Something I have learned the other day…
I had to install a small .msi using Group Policy, using a logon script. As it was a small package and not very important, I used a User Configuration Logon script.I created and linked a new GPO to a specific OU with some users (with no admin privileges) and client computers only. The script run well and the package installed very quickly on all machines in that OU.
The problem was that I have another OU with member servers and at the moment I logged on to one server using a normal user account, I had the package installed right after first logon. This is because I configured User Configuration logon script instead of Computer Configuration startup script.
What I’ve learned? That I should plan more careful even the installation of a small package.
