Installing COM+ Hotfix Rollup Packages
|This topic is applicable only for Windows Server 2003.|
You should install the last version of the Windows Server 2003 COM+ hotfix rollup package and latest version of the Distributed Transaction Coordinator (DTC) rollup package. This is because the packages include many performance and stability fixes.

The DTC issues that have been fixed are as follows:
Unexpected DTC shutdown
Memory fragmentation issues

DTC may leak memory or stop responding when used with BizTalk Server
Performance of DTC under load has been improved
