WINDOWS ADMIN MISTAKES

#1: Trying to change everything all at once

When you come into a new job, or start working with a new technology, you may have all sorts of bright ideas. If you’re new to the workplace, you immediately hone in on those things that your predecessors were (or seem to have been) doing wrong. You’re full of all the best practices and tips and tricks that you learned in school. If you’re an experienced administrator coming from a different environment, you may be set in your ways and want to do things the way you did them before, rather than taking advantage of features of the new OS.

Either way, you’re likely to cause yourself a great deal of grief. The best bet for someone new to Windows networking (or to any other job, for that matter) is give yourself time to adapt, observe and learn, and proceed slowly. You’ll make your own job easier in the long run and make more friends (or at least fewer enemies) that way.

#2: Overestimating the technical expertise of end users
Many new administrators expect users to have a better understanding of the technology than they do. Don’t assume that end users realize the importance of security, or that they will be able to accurately describe the errors they’re getting, or that they know what you mean when you tell them to perform a simple (to you) task such as going to Device Manager and checking the status of the sound card.

Many people in the business world use computers every day but know very little about them beyond how to operate a few specific applications. If you get frustrated with them, or make them feel stupid, most of them will try to avoid calling you when there’s a problem. Instead they’ll ignore it (if they can) or worse, try to fix it themselves. That means the problem may be far worse when you finally do become aware of it.

#3: Underestimating the technical expertise of end users
Although the above applies to many of your users, most companies will have at least a few who are advanced computer hobbyists and know a lot about technology. They’re the ones who will come up with inventive workarounds to circumvent the restrictions you put in place if those restrictions inconvenience them. Most of these users aren’t malicious; they just resent having someone else in control of their computer use — especially if you treat them as if they don’t know anything.

The best tactic with these users is to show them that you respect their skills, seek out their input, and let them know the reasons for the rules and restrictions. Point out that even a topnotch racecar driver who has demonstrated the ability to safely handle a vehicle at high speed must abide by the speed limits on the public roads, and it’s not because you doubt his/her technology skills that you must insist on everyone following the rules.

#4: Not turning on auditing
Windows Server operating systems have built-in security auditing, but it’s not enabled by default. It’s also not one of the best documented features, so some administrators fail to take advantage of it. And that’s a shame, because with the auditing features, you can keep track of logon attempts, access to files and other objects, and directory service access.
Active Directory Domain Services (AD DS) auditing has been enhanced in Windows Server 2008 and can be done more granularly now. Without either the built-in auditing or third-party auditing software running, it can be almost impossible to pinpoint and analyze what happened in a security breach.

#5: Not keeping systems updated
This one ought to be a no-brainer: Keeping your servers and client machines patched with the latest security updates can go a long way toward preventing downtime, data loss, and other consequences of malware and attacks. Yet many administrators fall behind, and their networks are running systems that aren’t properly patched.

This happens for several reasons. Understaffed and overworked IT departments just may not get around to applying patches as soon as they’re released. After all, it’s not always a matter of “just doing it” — everyone knows that some updates can break things, bringing your whole network to a stop. Thus it’s prudent to check out new patches in a testbed environment that simulates the applications and configurations of your production network. However, that takes time — time you may not have.

Automating the processes as much as possible can help you keep those updates flowing. Have your test network ready each month, for instance, before Microsoft releases its regular patches. Use
Windows Server Update Services (WSUS) or other tools to simplify and automate the process once you’ve decided that a patch is safe to apply. And don’t forget that applications — not just the operating system — need to be kept updated, too.

#6: Getting sloppy about security
Many administrators enforce best security practices for their users but get sloppy when it comes to their own workstations. For example, IT pros who would never allow users to run XP every day logged on with administrative accounts think nothing about running as administrators themselves while doing routine work that doesn’t require that level of privileges. Some administrators seem to think they’re immune to malware and attacks because they “know better.” But this over confidence can lead to disaster, as it does in the case of police officers who have a high occurrence of firearms accidents because they’re around guns all the time and become complacent about the dangers.

#7: Not documenting changes and fixes
Documentation is one of the most important things that you, as a network admin, can do to make your own job easier and to make it easier for someone else to step in and take care of the network in your absence. Yet it’s also one of the most neglected of all administrative tasks.

You may think you’ll remember what patch you applied or what configuration change you made that fixed an exasperating problem, but a year later, you probably won’t. If you document your actions, you don’t have to waste precious time reinventing the wheel (or the fix) all over again.

Some admins don’t want to document what they do because they think that if they keep it all in their heads, they’ll be indispensible. In truth, no one is ever irreplaceable — and by making it difficult for anyone else to learn your job, you make it less likely that you’ll ever get promoted out of the job.

Besides, what if you got hit by a truck crossing the street? Do you really want the company to come to a standstill because nobody knows the passwords to the administrative accounts or has a clue about how you have things set up and what daily duties you have to perform to keep the network running smoothly?

#8: Failing to test backups
One of the things that home users end up regretting the most is forgetting to back up their important data — and thus losing it all when a hard drive fails. Most IT pros understand the importance of backing up and do it on a regular schedule. What some busy admins don’t remember to do regularly is test those backups to make sure that the data really is there and that it can be restored.

Remember that making the backup is only the first step. You need to ensure that those backups will work if and when you need them.

#9: Overpromising and underdelivering
When your boss is pressuring you for answers to questions like “When can you have all the desktop systems upgraded to the new version of the software?” or “How much will it cost to get the new database server up and running?”, your natural tendency may be to give a response that makes you look good. But if you make promises you can’t keep and come in late or over budget, you do yourself more damage than good.

A good rule of thumb in any business is to underpromise and overdeliver instead of doing the opposite. If you think it will take two weeks to deploy a new system, give yourself some wiggle room and promise it in three weeks. If you’re pretty sure you’ll be able to buy the hardware you need for $10,000, ask for $12,000 just in case. Your boss will be impressed when you get the project done days ahead of time or spend less money than expected.

#10: Being afraid to ask for help
Ego is a funny thing, and many IT administrators have a lot invested in theirs. When it comes to technology, you may be reluctant to admit that you don’t know it all, and thus afraid — or embarrassed — to ask for help. I’ve know MCSEs and MVPs who couldn’t bear to seek help from colleagues because they felt they were supposed to be the “experts” and that their reputations would be hurt if they admitted otherwise. But plunging ahead with a project when you don’t know what you’re doing can get you in hot water, cost the company money, and even cost you your job.

If you’re in over your head, be willing to admit it and seek help from someone more knowledgeable about the subject. You can save days, weeks, or even months of grief by doing so.
