Event ID 1084 and event ID 1009 errors occur when you open an ASP.NET Web page in an Application Center 2000 cluster
SYMPTOMS
When you open an ASP.NET Web page in a Microsoft Application
Center 2000 cluster, you receive the following error message:
Server Application Unavailable
The web
application you are attempting to access on this web server is currently
unavailable. Please hit the “Refresh†button in your web browser to retry your
request.
Administrator Note: An error message detailing the cause of
this specific request failure can be found in the application event log of the
web server. Please review this log entry to discover what caused this error to
occur
The following event is logged in the application event log:
Event Type: Error
Event Source:
ASP.NET 1.1.4322.0
Event Category: None
Event ID:
1084
Description:
aspnet_wp.exe could not be started. The error code
for the failure is 80004005. This
error can be caused when the worker process account has insufficient rights to
read the .NET Framework files. Please ensure that the .NET Framework is
correctly installed and that the ACLs on the installation directory allow
access to the configured account.
Additionally, the following event
may also be logged in the application event log:
Event Type: Error
Event Source:
ASP.NET 1.1.4322.0
Event Category: None
Event ID:
1009
Description:
aspnet_wp.exe (PID: %1) failed to startup because the
synchronization event could not be initialized
The following files
have different versions:
aspnet_isapi.dll
System.Web.dll.
CAUSE
This problem occurs when you have two different versions of
some Microsoft .NET Framework 1.1 files installed in the Application Center
cluster. Two different versions of some files may be installed when you install
a .NET Framework service pack on a member server.
If you install a
service pack on a member server and not on the controller, the controller
replicates an earlier version of the Internet Server API (ISAPI) filter. This
filter was updated on the member server when you installed the service pack.
Therefore, on the member server, the System.web.dll file may be version
1.1.4322.2032 (SP1) and the ISAPI filter Aspnet_isapi.dll file may be version
1.1.4322.573.
Note This problem may occur when you install any .NET Framework
service pack on a member server.
RESOLUTION
To resolve this problem, use one of the following methods:
- Make sure that the versions of the .NET Framework 1.1 match
in the Application Center cluster. When you install the .NET Framework 1.1
service pack in the cluster, you must install the service pack on the cluster
controller first. Then, you must install the service pack on all the member
servers.
- Remove the .NET Framework 1.1 service pack from the member
server.
Note When you install a .NET Framework service pack, it is a good idea
to turn off replication until you have installed the service pack on all the
member servers.
