SCSM 2012 Portal silverlight to work on non dom

Question

Non domain computers – the sharpoint parts load (the silverlight does not
load). Domain computers can access the portal with no problem. I have also installed SCSM Portal certificate on non-domain machine added site in trusted site but no luck so far

This is usually because the WebContentServer (IIS site that loads the silverlight content) is not set to use the FQDN but rather just the hostname. Domain joined machines query DNS and will receive a reply with an address just based on the hostname. Non-joined
machines do not query any DNS when just a hostname is presented, therefore no address is returned. With that said, the SharePoint parts likely load because you either have a host file or are typing in the full URL in the browser which is hitting either public
DNS or a proxy. You will need to add an entry for the web content server the same way that you did for the SharePoint site
and perform the following. 
1. In IIS Manager, where the Service Manager Portal site is deployed, click on the Service Manager Portal site and select "Application Settings".
2. Make sure the SMPortal_WebContentServer_URL includes the FQDN of the web content server (can be the same server as SP or not). 
3. Navigate to C:\inetpub\wwroot\System Center Service Manager Portal\ContentHost on the server that the WebContentServer site is deployed in IIS and open the web.config file.
NOTE: ALWAYS make a copy of the web config before you edit it! This will allow you to rollback if necessary.
4. Near the bottom of the file, check the key "ContentHostAbsoluteUri" and ensure the FQDN is being used there as well. 
5. Once these changes are made, reset IIS. 
6. You may need to add both URLs (portal and web content server) to your trusted sites on the non-domain joined machine.
Hopefully that helps. :)
