Many corporate employees are often "on the road," required to travel from worksite to worksite while maintaining contact and sharing information with other individuals in the corporation. Routinely, these roaming workers use their laptop computers to help them share information.
If Novell ZENworks is installed in the corporate network, and if the ZENworks Management Agent is installed on a roaming user's laptop, he or she can install and run applications that process e-mail and create documents by logging in through the ZENworks Middle Tier Server.
If the corporate network's DNS is not sub-zoned, however, the roaming user may find it necessary to log in through his or her "home" Middle Tier Server, which may be hundreds of miles away and which may require the use of a WAN link. Even in cases where the roaming user tries to log in to an off-site Middle Tier and is presented with a list of Middle Tier Server names to choose from, the inconvenience, loss of time and money make this a less-than-desirable scenario.
