Common Issues with the OpsMgr Web Console

Common Issues with the OpsMgr Web Console

  • Comments 20

This post is a collection of the most common issues and resolutions I see with the SCOM 2007 R2 Web Console:

 

image Windows Auth on a non RMS.  The most common issue is typically where customers install the Web Console using Windows Authentication, on some server that is not the RMS.  Initially when SCOM released – this wasn't a supported configuration.  Later, post SP1, instructions were released on how to make this work – but it took some changes in Active Directory for constrained delegation for Kerberos.  Now – this can be done, but in real practice, I have found it to be hit-or-miss.  In some domains – no issues…. in others, it breaks easily, or only works some of the time.  In general, my recommendation is to use Forms Based authentication with SSL for Web Consoles that are not installed on the RMS.  If you want to give constrained delegation a shot – there are several articles on the web, including mine:

Unexpected error immediately after install.  Another common issue, is that you install the Web Console using Forms Based authentication, but get an “unexpected error”:

Unexpected error
There was an error displaying the page you requested.

Try the following:

Restart the web browser
Refresh the page
If you are still not able to view the requested page, try contacting your administrator or Helpdesk

This is caused by installing the Web Console using Forms based authentication, but not having SSL set up yet.  Marnix wrote a great post on this topic:  http://thoughtsonopsmgr.blogspot.com/2010/03/scom-web-console-with-form-based.html

Bottom line – we recommend setting up SSL on IIS for the Web Console…. but if you dont have this set up yet – you need to edit the Web.Config file and change:

<authentication mode="Forms">
  <forms requireSSL="true" />
</authentication>

to

<authentication mode="Forms">
  <forms requireSSL="false" />
</authentication>

Web Console takes a long time to load and ASP.NET logs Event ID: 1309

 

You might see the web console take a very long time to load, and eventually even time out with:

Event message: The request has been aborted.
Exception information:
Exception type: HttpException
Exception message: Request timed out.

You might also get the following event in your application event log:

Event Type: Warning
Event Source: ASP.NET 2.0.50727.0
Event Category: Web Event
Event ID: 1309

Is authenticated: True
Authentication Type: Negotiate
Thread account name: NT AUTHORITY\NETWORK SERVICE
Thread information:

Stack trace:

This can be caused by an IIS configuration – the SCOM Web Console website was configured to use Anonymous AND Windows Integrated Authentication, when ideally it should be configured to use ONLY Windows Integrated Authentication.

To resolve – you can uncheck Anonymous Authentication and then perform an iisreset.

 

imageCannot install/uninstall the web console.

Often times – this is an issue for Web Consoles that were upgrade from SP1 to R2.  Many times – this is due to old path information in the registry.

1. Go to registry editor on web console server.
2. Locate “My Computer\HKEY_CLASSES_ROOT\Installer\Products\DF6E5EFF035E66C49971553D96AA0E4D
3. Back up the registry key in step 2
4. Go to patches value and delete entry for “patches” REG_MULTI_SZ
5. Continue with the upgrade/uninstall/install.

  • Hey Kevin,

    Came upon this post and thought of presenting my issue.

    On most of my consoles, whether on my workstation or my management server where the webconsole is installed i get the message  "The page cannot be displayed".  I can open the Monitoring pane, see the list of active alerts and the monitoring tree on the left pane. But in the bottom right pane for Alert Details I get "Page cannot be displayed".

    I am not sure if there is something wrong with my backend setup that is causing this. Do you have any thoughts on what i can checkup ?

    Thanks

    G

  • try to delete temporary internet page in your IE. if not worked, then delete your profile. It should work !!!!!

  • Thanks for the great post!


  • hi Goon,
    I resolved this today. I had to uninstall Silverlight from add/remove programs and then reinstall it again.
