Netflix Player Error – Error Code: 2103

Netflix is one of the premier online streaming sites for TV Series and Movies that you can watch straight into your browser or through Windows Media Center. Personally, I enjoy watching films over on Netflix. You may not get the latest shows and movies but its good enough for some R&R.

Resolving this error is easy enough:

METHOD 1: Deactivate your Netflix ready Device.

1. Open a browser, login to your Netflix account and then look for the option of “Your Account and Help”.Capture Netflix Option

2. Once inside your account information page look for “Manage Netflix ready devices and computers”.
3. Depending on the device you activated, choose the one where you are having this error and then click “Deactivate”.

Capture Netflix Ready Device

4. Log-off your account and then close the browser.
5. Open your browser or Media Center and try to play your movie again.

METHOD 2: Reinstall Microsoft Silverlight.

1. Uninstall and reinstall Microsoft Silverlight.
2. To remove Microsoft Silverlight, go to:
        a. Control Panel\Programs\Programs and Features, in Windows Vista or 7.
        b. Control Panel\Add or Remove Programs, in XP.
3. Locate and uninstall Microsoft Silverlight.
4. To reinstall Microsoft Silverlight you may either “Check for Updates” using Windows Updates using this link: http://www.update.microsoft.com or go to this link to check and get the latest version: http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx 
5. Once Microsoft Silverlight is installed retry your movie.

METHOD 3: Reinstall Netflix in Media Center.

1. Uninstall and reinstall Netflix in Media Center.
2. To remove Netflix in Media Center, go to:
        a. Control Panel\Programs\Programs and Features, in Windows Vista or 7.
        b. Control Panel\Add or Remove Programs, in XP.
3.  Locate and uninstall “Netflix in Media Center”.
4. To reinstall “Netflix in Media Center” we need to run Media Center’s Update:
        a. Exit all instances of Windows Media Center.
        b. Open an administrator Command Prompt. To do this, click Start.
c. Click All Programs, click Accessories.
d. Right-click Command Prompt, and then click “Run as administrator”.

Note: If you are prompted for an administrator password or for confirmation, type the administrator password or provide confirmation.

         e. Type the following commands, and then press ENTER after each command:

             cd /d %WINDIR%\ehome
             start /wait mcupdate –uf

         f. Media Center should retrieve any available updates from the server. Check your System Tray.

                   Capture Media Center Update retrieval

5. Type EXIT after the update retrieval, and then press ENTER to exit the Command Prompt window.
6. Reopen Windows Media Center. The Netflix option should be displayed on the left side of Movie Library on the Movies row.

    I think I found the fix for Vista that is less labor intensive, at least it worked for me. Open the control panel and go to Programs and Features. Then open the features dialog and go to:

    Internet Information Services->World Wide Web Services->Common Http Features->Static Content

    and check it to turn it on. Don’t be impatient because when Windows tells you it takes a few minutes to update your settings, they really mean it. It was worth the wait, because now Netflix works on my PC.

    I found this on the Silverlight Developers Forum.

    Ok I tried several things in order to get this fixed, and yea it is now working.

    This is what finally worked for me: Under Internet Options go in and delete all of the history and cookies, then go to the advance tab look under securiy click the “empty temp internet files and folders upon closing browser” save changes. This way when you load netflix the system has to look for the netflix app.

    Uninstall and reinstall- didn’t work

    Took IE9 back to IE8- didn’t work so I went back to IE9

    Deleted all of the silverlight n the reg. Use regedit, then delete everyfile related to silverlight, reboot system and reinstall- worked for a little while- because I forgot to delete the cookies- it probably would have worked perm if I had deleted the cookies first LOL .( you should not try this unless you truly know what you are doing).

    reset the default in the internet options- this will work but remember this is permanent and you will have to update you IE again.

    Hope this helps, and good luck.

    Hello, Mr. Weng, and thank you for your expertise. I, too, was having trouble with Silverlight NetFlix error 2103. I followed all your steps from this forum and the forum in the “Failed Silverlight Installation”. My final steps were to update the windows installer 4.5 from the link you provided in “Failed Silverlight Installation”, I deleted all history, cookies, etc. (except for the last time, I unchecked preserve all my favorite website info), uninstalled Silverlight, restarted computer, used your link to download Silverlight and saved it to my hard drive, opening it from there. Then, I retried Netflix again; it worked! Thank you, much; much appreciated from this sixty-year-old lady.

    Oh, if you need to know, I have Windows XP, SP 3

      That’s what I did, too. Netflix told me to uninstall and reinstall silverlight. I did that – three times. Emptied browser history and temp internet files and still didn’t work. Microsoft website said the program was working fine and ready to use. Called Microsoft and they wanted $99 to solve my problem. So,

      I uninstalled Silverlight.
      Downloaded Silverlight again only this time I saved the file instead of running it.
      I went to the screen where you delete temp internet files and deleted everything except my passwords.
      I closed all windows and opened my saved silverlight installation file and downloaded it from there.

      Then it worked! Thank God, I didn’t pay Microsoft $99 for them to tell me how fix their substandard program.

    But what if one is trying to watch on a MAC running Safari?

    This has been so exasperating – any thoughts to try to fix it are most appreciated…

    November 27, 2013 at 1:17 PM

    • Silverlight works for Safari on MAC.
      I suggest to follow the removal steps from here: http://www.microsoft.com/getsilverlight/get-started/install/removing-silverlight-mac.aspx
      Afterwards, install Silverlight using Safari through this link: http://www.microsoft.com/silverlight/resources/install.aspx

        I’m embarrassed (and relieved) to say that it has been my Kaspersky internet security prompting the SilverLight reinstall prompts – which is why doing so never worked. I’ll look further into why Kaspersky seems to be blocking Netflix only, but turning it off for the second Netflix loads and then turning it back on immediately is doing the trick meanwhile.

        Many thanks… 🙂

      • Much of the Anti-Malware products today have tighten their security features that hinders updating of legitimate executable files. I had the same experience on Avast and Avira too. Hopefully, those that stumble across on this resolution can find it useful to also check if their current AM/AV is blocking updates or installation of known and safe apps.
