DOCUMENT:Q315095 17-MAY-2002 [sna] TITLE :FIX: WMI Queries Stop Responding on Host Integration Server 2000 PRODUCT :Microsoft SNA Server PROD/VER:: OPER/SYS: KEYWORDS:kbhis2000 kbhis2000bug ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Host Integration Server 2000 ------------------------------------------------------------------------------- SYMPTOMS ======== If multiple instances of a Windows Management Instrumentation (WMI) application (for example Wbemtest.exe) are configured to repeatedly issue WMI queries against the same Host Integration Server 2000 (HIS) server, after a while, one or more of the instances of Wbemtest stops responding. When this problem occurs, all of the applications that use the HIS WMI provider will fail to return status information and will not function as expected. CAUSE ===== The Host Integration Server 2000 WMI provider encouters a resource deadlock that causes all current and later WMI queries to stop responding.
