Like other working disciplines that constitute the IT industry, you may find a few network administrators that can make it very hard to get the job done. Most network administrators are competent and good at their jobs as keeping things humming along smoothly can be a technically difficult and highly challenging role. However, occasionally some can turn rogue and make your life miserable.

1. Mr. Safety, they are anxious in preventing anything bad happen in their network.  Their method for avoiding disaster is to lock the whole system down so tightly that no one or nothing can change anything. Sometimes, users are asked to use long and complex passwords, which will be set to expire every week or month. To prevent the spread of a virus, they may insist that all USB sockets in every workstation are to be disabled in BIOS and password-protected, all files that enter the network must be approved by IT staffs. The e-mail server wont allow any attachments and the workstations cannot boot if the LAN cable is disconnected
2. The Accidental Administrators, they are not educated in network management and develop the skill as the company grows. So 20 years ago, when their companies bought a few new computers to assist with the paperwork and accounting, they were the slowest to leave the office and thus acquired the unofficial role as the “computer guys”, although officially they are still full-time accounting/general affairs staffs. The company grows and it has hundreds of employees, while the network also grows in spurts to keep up. The company now has more than a fifty workstations cobbled together to make a makeshift network, with e-mail gateway, Internet proxy server, and file server. There is no network documentation. All of the details are in the computer guys’ head and everything just about jog along, as long as nothing untoward occurs. The company cant quite hire a full-time IT person, as the whole company feels comfortable with the accidental administrators. All in all, things can work quite well if you dont mind the amateurish network structure, inefficient configuration and the unavoidable virus attacks. Everybody may have the same password and all folders are shared to the public, but it doesn’t really matter too much as everyone in the company is absolutely trustworthy and nice.
3. The Remote Deployment Lovers, they master the art of remote applications deployment and proud of it. They configure all the workstations on the network to WOL (Wake-On-LAN). You may leave work at 5 PM after shutting down your computer and then the next morning find that someone had messed around with it.
4. The Test Bed Administrators, they try out new upgrades and patches all the time. Good administrators use a small test LAN on which they experiment with a new solution before deploying it to the whole system. Test Bed administrators treat the company system as a testing arena, much to the annoyance and consternation of other employees.
5. The Possessive Administrators, as the name suggests, the company network is their personal estate, and they will become agitated whenever someone tries to do anything that may affect the smooth running of their network. They will keep exhaustive logs that show network efficiency is nearly 100 percent. It is achieved by making sure that that hardly any of the free network resources are allocated for unneeded usages.
6. The Gaming Administrators, they are the rarest and probably the friendliest type of bad administrators found in large networks. For example, the network may have enough resources to allow a few hundred students to work on their research or papers but its hidden main function is to provide a university-wide gaming platform for a few dozens students. Large percentage of network resource is used by those who love to blow each other out in multiplayer games.
