A growing number of analysts are warning users not to expect delivery of Windows 2000 before the middle of next year. However, resellers and integrators appear unfazed. The timeframe projected by analysts is at least six months after the delivery date pinpointed last week by Ed Muth, Microsoft's group product manager for Windows NT. Muth's revised date came after Microsoft announced a one-month delay in the release of the third beta of the Windows NT upgrade. In a statement last year, it pegged mid-1999 for the final release of Windows 2000.
