XFOR: CDONTS Not Thread-Safe, Crashes Under Stress

This article was previously published under Q214685
This article has been archived. It is offered "as is" and will no longer be updated.
The Collaboration Data Objects for Windows NT Server (CDONTS) Send Mail function is not thread-safe.
CDONTS initializes the RTF/HTML converter each time it is used. This initialization is not thread-safe, and is not protected with a critical section. This permits a race condition where one thread can shut down the converter while another thread is still using it, causing memory corruption, asserts, and failures (crashes).
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
