The update, Windows 2000 Service Pack 3, contains vital security updates and hundreds of fixes to bugs plaguing the operating system that Microsoft released in February 2000. Service Pack 3 could be important for many businesses, as not all of the included security fixes are available as separate downloads.
But some businesses won't find this to be a light download, which weighs in for some installations at more than 150MB, according to the update's "Read Me" file. Service Pack 3 can be applied to Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server and Windows 2000 with Server Appliance Kit. The size of the update could change depending on the version of Windows and type of installation, such as single computer or network.
Microsoft would not give a specific release date for the service pack. "We remain on track to release this summer and we will ship when it is ready," said Jim Cullinan, Windows lead product manager.

The release of a first service pack is considered a watershed event for many larger companies, which typically wait for the fixes before moving to a new operating system. A third service pack would normally be part of the ongoing process of fixing bugs.
But with Windows 2000 Service Pack 3, Microsoft is expected to make many changes that could improve the overall of security of the operating system.
Microsoft started taking Windows 2000 security more seriously in January, after Chairman Bill Gatesa company-wide about putting security ahead of adding new features to products. Soon after, Microsoft a package of cumulative security fixes.
"There probably will be some important security stuff in there related to their security initiative," said IDC analyst Al Gillen.
But theof Windows .Net Server, the successor to Windows 2000 Server, is another reason why this update will be important to many businesses.
"It's an important service pack, especially after such a long period of time; this hits the server as well as the desktop," said Gartner analyst Michael Silver. "Remember, there is no replacement on the server."
Microsoft now expects tofinal, or gold, code to Windows .Net Server sometime before the end of the year, but many customers would likely not see the product before early 2003.
At the same time, many companies continue to move older Windows 95, 98 or NT systems to version 2000, even though Microsoftsuccessor XP in October. Gartner predicts that Windows 2000 PCs will easily those with XP this year, respectively, 41 percent to 16 percent of new system sales.
For this reason, Gartner predicts Windows 2000 will be widely used much longer than Microsoft anticipates.
"End of life (for Windows 2000) is supposed to be first quarter 2004," Silver said. "We're predicting that Microsoft will extend that date for Windows 2000 Professional support."
As the release of Windows 2000 Service Pack 3 approaches, Microsoft is rapidly working to release the first collection of bug fixes for Windows XP. That service pack is slated for late-summer release and will introduce many changes to Windows XP.
Besides bug fixes and security updates, Windows XPwill how PC makers or consumers interact with so-called middleware, such as Web browsing or instant messaging technologies.
Microsoft is making these changes in accordance with an antitrustcut with the Justice Department and nine of 18 states. Final status of the November agreement is pending, awaiting final word by a federal judge in Washington.
On Monday, Microsoftits version of the Java Virtual Machine (JVM) from a download site. The company plans to its version of the JVM, which competes with newer versions available from Java inventor Sun Microsystems, to Windows XP with the release of Service Pack 1.
Gillen said he expects to see some middleware and other changes to Windows 2000, also in response to the antitrust settlement.
"I know they have to do some stuff on the client, but I don't know if they will do anything on the server. That is a possibility, because they have to expose the client-server protocols," he said.
