ADSI Requests on LDAP Objects May Hang Multiple-Threaded Programs (272365)
The information in this article applies to:
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Advanced Server
- Microsoft Windows 2000 Professional
This article was previously published under Q272365 SYMPTOMS
When you are using the ADSI LDAP provider in a multiple-threaded program, threads may not return from an LDAP request.
CAUSE
This issue is caused by a critical section not being released by the first thread to make a request. Therefore, subsequent threads cannot enter the critical section and seem to stop responding (hang).
This problem is not apparent in programs that effectively run "single-threaded" (such as CScript programs), but is noticeable in programs in which requests run on multiple threads (such as Microsoft Internet Information Services).
