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.

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:
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Windows NT version 4.0 Service Pack 5.
