"Many of us have that one remaining NT server, or old UNIX application running. Generally it's something that has worked for years and doesn't impact too many customers so we've never upgraded it," Sawyer says. But even technologies that need little to no attention still can be costly in terms of licensing and they impede efforts to streamline the network. "Most likely these technologies are no longer supported nor are they compatible with newer technologies so it's time to say good-bye," she says.

She recommends bringing all technology up to speed and in line with your enterprise strategy -- such as an upgrade to a newer version of Windows Server if you're a Windows shop. This allows IT to do volume licensing, streamline support and consolidate resources -- all of which can result in significant cost savings.

Other technologies that IT pros have on their radar screens for annihilation: FTP in favor of virtual private networking and ubiquitous e-mail encryption, and tape-based dictation machines in favor of digital recording programs. IT managers say you should walk around your organization, look in each office and storage closet, identify aging technologies, and you'll quickly see opportunities to save hard dollars.

If you had the opportunity to rip and replace parts of your network, what would they be? Is there any gear that users are clinging to that is draining you in terms of upkeep? Let me know at sgittlen@charter.net.
