FIX: Msxml2.dll Fails to Register on 32-Processor Computer During MDAC 2.6 Installation

When installing Microsoft Data Access Components (MDAC) 2.6 RTM (version 2.60.6526.3) on computers that have 32 processors, the following error may occur when Msxml2.dll is registered: This error occurs with Msxml2.dll version 8.0.6518.2. It may be encountered when installing SQL Server 2000, which includes MDAC 2.6.

NOTE: This problem does not occur with the MSXML 3.0 parser (Msxml3.dll version 8.0.7820.0).

Like many of the MDAC components, Msxml2.dll allocates number-of-processors+1 heaps during initialization to avoid heap contention. On a 32-processor computer, this exceeds an internal memory limit of 300K.

To resolve this problem, obtain the latest service pack for Microsoft Data Access Components 2.6. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
