UNIX offers a breadth and level of stability that is unmatched by other operating systems. Being 25 years old qualifies UNIX as the granddaddy of small computer operating systems. More applications are available for UNIX than NetWare and NT Server combined. Contrary to popular opinion, UNIX system administrators are not propeller heads who secretly sacrifice chickens to make the system operate. Like every other operating system, UNIX has an interface and a set of utilities that must be learned.
Network administration requires highly trained, full-time personnel.
UNIX environments require solid network skills every bit as much as NetWare and NT Server. Making Sharon the network administrator because she's sitting closest to the file server is not good business. Network operating systems may be easy to install, but they do require experienced personnel to handle problems when they arise. UNIX is the platform of choice for several key network functions. Network-monitoring products like HP OpenView are better suited for this platform.
