Install Groove Networks nifty synchronization software, Laplink Software Inc.s Laplink Remote or Citrix Systems Inc.s GoToMyPC to let you sneak inside the firewall while at your local coffee shop.

Ive heard some IT managers complain. "Weve got e-mail." Well, its the difference between a letter and a phone call. IMs instant and provides an easy way to share info and keep track of far-flung employees. Plus, it offers a quick and dirty replacement should your corporate e-mail system go on the fritz. Advanced versions allow for quick file-sharing and will even set up free Internet voice and video calls. IT: Use policies to prohibit installation of any unapproved application. Block IM ports on your firewall. Instruct your staff to keep a listen out for the telltale "boop-beep" that signals in incoming IM. Quickly delete and warn offenders. Users: Web versions of AIM and other popular IM clients make discovery unlikely. Use Trillian or another cross-IM client in case IT shuts access to one or the other. Middle ground: Its not just for the pimpled and tattooed crowd anymore. My advice: Try it. For quick communications and figuring out if someones reachable, theres nothing like IM. If your corporate policies or the law require tracking and retaining instant messages, then consider a secure solution. Yahoos got a decent one, as does Groove.
