Silverlight Stream Freezing when using computer's Hostname in URL RRS feed

  • Question

  • Hello,

    We have an interesting problem that seems to have happened on updated machines. We have a Windows Server 2012 PC hosting a webpage that is displaying Video Streams of IP cameras. On the Server PC, logged in as an administrator, we open IE11 to the computer's hostname: http://<hostname>/page/  When we open the page the stream starts and seems to work fine, but then after some seconds (varies 3-60 seconds) the stream freezes with no errors or warnings being displayed (or found). Refresh the page, it streams but again it freezes after varying seconds. Web page works fine, and the stream is still captured but the silverlight client seems to crash. Interesting part of this is if we use the Servers IP address or localhost in place of the computers hostname, the stream works fine and doesn't freeze.  Other PCs on the network connecting using the computers hostname work fine as well, so it seems to be only happening when opening the webpage from the hosting machine. 

    The systems that have experienced this issue are connected to the internet and have been updated to the latest windows updates. We have other clients that aren't experiencing this issue that haven't updated their machines. This problem seems to have started after an update in March. I haven't started to roll back updates yet and want to see if there are any information before trying that. 

    I have tried to revert and lower all security settings and IE settings to see if there is anything there but have had no luck. Reinstalled Silverlight and cleared all cache but still no luck. I have tried to debug this issue to find any warnings or errors but have come up empty. I am not sure if it is a DNS hiccup, silverlight domain restriction, or something else....

    Any thoughts would be greatly appreciated and let me know if any information is missing.

    Thank you,

    From your description, I suggest you can try some tools to test your Silverlight Applications and show more detailed information.

    You can  roll back updates and try again. If the problem does not exist. I suggest you can report your question at Connect:
