Microsoft has recalled an updated version of Small Business Server because of a glitch discovered during a regular software production audit, the company said Friday.

The update, called Small Business Server 2003 R2, contained non-final versions of some core components. However, it had only been released recently to original equipment manufacturers, system builders and distributors, and was not generally available to customers, according to the company.

Microsoft is recalling and reissuing the production so far of R2. That will lead to a minor delay in general availability, the company said. Earlier this month at its launch at the Microsoft Worldwide Partner Conference, Microsoft said the product would be available in August.

Small Business Server 2003 R2 will incorporate the Windows Server 2003 operating system, the SharePoint Web portal, Exchange Server groupware and Office Outlook e-mail software.
