This article was previously published under Q297696



SYMPTOMS
When a connection needs to be allocated during a transaction, the Dispenser Manager always searches the list of free connections. As a result, the Dispenser Manager may enlist a new connection in the transaction even if free connections are already enlisted in that transaction.

This has two side effects:


 * It appears that connection pooling does not work with Microsoft Transaction Server or COM+ because new connections are opened and enlisted in the transaction.
 * Databases such as Oracle and DB2 may encounter enlistment failures.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 2.
