A Dllhost.exe process may stop responding when it is associated with a package that contains a COM Transaction Integrator component

View products that this article applies to.

Symptoms

A Dllhost.exe process that is associated with a Microsoft COM+ application package that contains a Component Object Model (COM) Transaction Integrator (COMTI) component may stop responding. The problem occurs intermittently, but it may occur more frequently on systems that have fast or multiple processors.

An application dump file of the unresponsive Dllhost.exe process shows a thread that is blocking on a critical section and the owner of this critical section has been orphaned.

Workaround

To work around this problem, rename Snasii.dll. Snasii.dll is used for the Single Sign-On (SSO) service.

If the COMTI Remote Environment is configured to use SSO, do not rename Snasii.dll.
