Extensive directory integration work has prompted electronics manufacturer Texas Instruments (TI) to delay its plans to move to Windows 2000 by at least a year.
TI's current system is based on Windows NT4 and Novell Directory Services (NDS). The company has found integrating these networks with Windows 2000's Active Directory time-consuming and costly - a problem forecast in Computer Weekly in September 1999.
Greg Speer, TI's project manager for the NT architecture team in Dallas, said, "The design phase highlighted barriers to moving forward. Our existing directory services in TI are integrated with applications which are written to that particular format. It will take time to change this if we are going to avoid customer disruption."
However, Speer said none of the problems were insurmountable. "We are officially in a holding pattern while we look at what is needed and it could be at least a year to 18 months before we move to Windows 2000," he said.
Directory integration is a problem for many large organisations. TI's user base comprises over 30,000 users.
Gary Barnett, principal analyst at Ovum, said the introduction of Windows 2000 was more difficult in large organisations. "In larger companies it will be more common for some other directory service to be already in use and for Microsoft to pursue these big-time accounts it will have to make sure that the technology plays nicely with, or integrates with, competing systems," he said.
