I gotta check in here humm looks like I'm the old fart again LOL. The work place always is a challange. First off an MCSE is a hunk of paper (costly) and with each release it is also outdated quickly now days. I'd say watch the logs on the server print them out and oh go to that person and say BTW I'm busy you did the install can you correct it? You made no mention of any sort of firewall or I may have missed that part. But this person may think if there is one there is no need to do anything but a default install (a newbie MCSE thinking seen it many times). Manage the firewall right and the risk to the server is small from the outside. But being a work place you have to take into account the lame users and how they might exploit the server. Say access those files they should not or directories, only takes one lame user to have the wrong access to a server to really mess a network up.

One thing I have found in some 20 years in IT is yeah there are people smarter, and at my age now to damn quick they can hit re-start faster then I can say WAIT! My advantage over these people 30 years supporting the business, knowing it all. Sometimes out geeking a geek is simply a matter of knowing the operations and functions of the business you support better then they can. Like I know A/E inside and out maybe there is a better geek then me to do it but I know what the end users need and what A/E operations are about, an MCSE knows well MCSE...dah lets re-boot and not tell anyone..or humm lets Fdisk and re-install to fix that problem cause I have no clue. Forget the MGR and brown nose stick with business operations and what functions are needed on the network, the newbe will hang himself.
