BUG

ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch may not install completely to all Web Adaptor instances due to a file lock

Last Published: December 15, 2023

Description

If a file lock is present when installing the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch, it may not install completely to all Web Adaptor instances despite a successful response from the setup program.

Note: 
This defect also affects the ArcGIS Web Adaptor (IIS) 11.1 Reliability Patch, which has since been removed for download because it was superseded by ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch.

Cause

There is a file lock present which prevents the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch from being completely installed.

To confirm if you are encountering this issue, wait for the patch install process to complete for all instances of the ArcGIS Web Adaptor (IIS) you have installed, then complete the following:

  1. Open Windows Explorer, and navigate to inetpub/wwwroot/(context) folder, where (context) is the name of the ArcGIS Web Adaptor instance. Check the date stamp on the ESRI.ArcGIS.WebAdaptor.dll. If the date stamp is not August 10, 2023, then the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch has not been applied to this ArcGIS Web Adaptor instance.
  2. Repeat this check for each ArcGIS Web Adaptor instance on the machine. For example, an ArcGIS Enterprise deployment installed by the ArcGIS Enterprise Builder will create two instances of the ArcGIS Web Adaptor (IIS), one is named portal and the other is named server. In this example, the application pools will be named ArcGISWebAdaptorAppPoolportal and ArcGISWebAdaptorAppPoolserver.
    • If there is uncertainty about how many ArcGIS Web Adaptor (IIS) instances are installed on the machine, go to the Windows Control Panel > Programs > Programs and Features to see the list of installed ArcGIS Web Adaptors with their respective instance names.

Workaround

Esri has released a corrected version of the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch, with a B version suffix, with additional install logic so these manual steps of restarting the ArcGISWebAdaptor application pools are not necessary.

After confirming the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch was not fully applied, follow these steps to apply the patch.

  1. Close the Windows Explorer that was used to view the ESRI.ArcGIS.WebAdaptor.dll date stamp. This step is important to ensure no inadvertent locking of Web Adaptor files
  2. Open Internet Information Services (IIS) Manager.
  3. Click the Application Pools node in the tree view.
  4. Based on the results from your findings in the Cause section, stop all ArcGISWebAdaptor application pools that have not been updated. For example, if both the portal and server instances were not updated, right-click ArcGISWebAdaptorAppPoolportal and choose Stop. Then right-click ArcGISWebAdaptorAppPoolserver and choose Stop.
    • Note that depending on the activity of your web server, the actual stop and release of files may take longer than is indicated by the Internet Information Services (IIS) Manager user interface.
  5. Close Internet Information Services (IIS) Manager.
  6. Run the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch. Wait for the patch install process to complete for all instances of the ArcGIS Web Adaptor (IIS) you have installed.
  7. Open Internet Information Services (IIS) Manager.
  8. Start all ArcGISWebAdaptor application pools. For example, right-click ArcGISWebAdaptorAppPoolportal and choose Start. Then right-click ArcGISWebAdaptorAppPoolserver and choose Start.
  9. Open Windows Explorer. Navigate to inetpub/wwwroot/(context) folder where (context) is the name of the ArcGIS Web Adaptor instance. Check that the ESRI.ArcGIS.WebAdaptor.dll has a date stamp of August 10, 2023. Repeat this check for every ArcGIS Web Adaptor (IIS) on the machine.
  10. If you find that the ESRI.ArcGIS.WebAdaptor.dll still does not have a date stamp of August10, 2023 after following this workflow to apply the ArcGIS Web Adaptor (IIS) 11.1 Reliability Update 2 Patch, please log an incident with Esri Tech Support.
