Being an enforcer - like it or not -comes with the territory for network professionals.

However, that territory keeps expanding as spam and sexual harassment liability make e-mail and Web-use monitoring commonplace; rogue wireless access points keep an IT posse running building to building; unauthorized software causes unnecessary support headaches; and the government cranks out privacy regulations faster than $20 bills.

Laying down the law might be part of the job, but diligence can win you a chilly reception in the lunchroom.

Yet most network executives remain perfectly willing to play Dirty Harry (or Harriet) in the interest of keeping their employer's network up, clean and law-abiding. Yet they'd like to see a little more support from the top brass than Clint Eastwood's notorious character enjoyed on screen. You might say it would make their day.

"I always had to be the bad guy, and my superiors would dodge the bullet when employees complained to them directly," says Chey Cobb, who has overseen networks for U.S. intelligence agencies. "Of course, the superiors always felt they were above the rules and engaged in these improper activities themselves," adds Cobb, now a consultant and author.

Being painted as the bad guy can take a toll, Cobb says. While a network manager: "I was angry, sad and disturbed to find out that my so-called friends were talking me down. In one instance . . . I was uninvited to after-work drinks," she says.

A network manager at a large manufacturing company describes the typical rank-and-file attitude: "Twice in a week, recently, I had to remove software from two PCs. Someone had installed WeatherBug and the associated spyware, and another had installed a Harry Potter screensaver. When I told the users the software had to go, they both responded, 'Like I'm the only one.' "

The network manager, who requested anonymity, says, "I thought, 'No, you're not the only one making my job harder than it has to be.' " Of course, he adds, "you can never really say what you think."

Which might explain why some enforcers relish looking for a bit of sport in the role.

"Some of it is even fun," says Michael Lester, a network professional who asked that his company not be named. "I have hunted down unlicensed software, games, .avi files, sound files, screen savers, all kinds of stuff that does not need to be on company PCs. The look on their faces when they get the 'Access denied' message after clicking on the Deer Hunter icon . . . needs to be seen to be appreciated."
