TITLE   :Cluster Administrator May Hang Creating New IIS Server Instance
PRODUCT :Internet Information Server
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:kbiis400bug

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Internet Information Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Microsoft Cluster Administrator may stop responding when adding a new Microsoft
Internet Information Server (IIS) Instance after Windows NT 4.0 Service Pack 4
has been applied to the cluster nodes.

CAUSE
=====

The Cluster Administrator stops responding (Clusadmin.exe) because of a Second
Chance (non-recoverable) Access Violation in the Cluster Resource Monitor
(Resrcmon.exe). The Access Violation in Resrcmon.exe causes Remote Procedure
Call (RPC) failures in Clusadmin.exe while trying to execute code in
Resrcmon.exe. The RPC failures causes Clusadmin.exe to stop responding as
Clusadmin.exe continually tries to execute code in the failing Resrcmon.exe.

The Second Chance Access Violation occurs when the IIS 4.0 resource monitor
extension (Clusiis4.dll) attempts to build the meta data path to the new site on
the node so that all the property changes can be remotely transferred to nodes
in the cluster per the Windows NT Service Pack 4. This design change is
described in the following Knowledge Base article:

   Q224293 IIS Cluster Admin. Extension Cannot Remotely Administer IIS in a
   Cluster
