Your client does not support opening this list with Windows Explorer + IE10 + Windows 7

The title of this article itself suggesting the exact problem description, still here are the details:

The machine on which windows 7 is running along with internet explorer 10 throws an exception when you select “Open with Explorer” in SharePoint Server 2010.

Error Message#1: Your client does not support opening this list with Windows Explorer.

Error Message#2: We're having a problem opening this location in File Explorer. Add this web site to your Trusted Sites list and try again.

Another Symptom:
You try to map a network drive to the SharePoint Document Library and the operation fails with the following error:

The mapped network drive could not be created because the following error has occurred:
Access Denied. Before opening files in this location, you must first add the web site to your trusted sites list, browse to the web site, and select the option to login automatically.

Let me provide you some update on this / let me give you some good news as Microsoft has released a fix for this issue by means of KB: 2846960

Fix can be downloaded from: http://support.microsoft.com/kb/2846960

Millions thanks to Microsoft Windows team to find out the root cause behind this and comes up with a concrete fix.

Happy SharePoint to all of you…


  1. Simply perfect! Thank you...

    1. It's great that my article helped you to get the insight that you are looking for! Do let me know in case of any issues, Thank you.

    2. When I enable both authentication (Windows and FBA) on default zone following error is occurred.
      "Your client does not support opening this list with Windows Explorer."
      Web client service is running on server.
      Desktop Experience feature is also enabled on server
      Windows explorer is working fine when FBA is disbled on default zone.
      When I disable / Unchecked FBA from Default Zone, windows explorer working fine.
      But I need to enable both on same default zone.

    3. From your question, it is by design. There are two protocols for explorer view: WebDAV and RPRPC. The first one can’t work with SSL site, the second one can.

    4. Thanks for Reply Amol,

      I have one more query,

      I have one web application contains two zones Default & Extranet,

      Windows Auth enabled on default zone
      FBA enabled on Extranet zone.

      when I search FBA users in Default zone site in people picker its not working means FBA users are not working on Default zone,

      Scenario is, default zone is for internal users only when a internal user want to assign any task to external user / vendor he cant.

    5. Which authentication provider you are using for FBA?

      also, Did you make the proper changes inside web.config?

    6. If you enable both the providers (FBA and NTLM) on the default zone (NTLM) in Central Administration then SharePoint can resolve and add the users to the security groups or site administrators collection. But this changes the user’s login experience. Now the user has to choose which authentication mechanism he wants to use.

      This is not always acceptable as it confuses the business users. The workaround for this is to modify the login page and redirect the user to the login page that you prefer (FBA/NTLM)

      let me know in case of any queries, thanks

  2. Does this fix works with internet explorer 9??

    1. Thank Amol!!

      I am having trusted site zone issue with open with explorer and is using IE9.

      I did all the steps:
      webclient is started
      clear browser
      add the site to trusted zone
      use ie 32
      But still the issue is not being resolved. We have sp2010

      I hope this hotfix works for IE 9 or downgrade to ie 8

    2. few suggestions

      - Reset the IE (IE-> tools-> IE options-.> advanced -> Reset

      if this doesn't work then

      Try to run the site in "Compatibility mode" make sure the protected mode is off.

      if this doesn't work then go for this: IE->advanced ->Security section -> uncheck publisher certificate revocation

      let me know the results, Thank you

    3. First of all i like to thank you for responding to my post, greatly appreciated. I was able to fix the open with explorer issue with this hotfix for ie10, yay!

      I couldn't get a chance to fix the open with explorer issue with ie 9 but I am making note of your suggestion so that i can try it if someone else report this issue again. Thanks a lot.

      You really have nice blog, a lot of information and nicely written, please keep blogging :)

    4. Great to hear that the issue has been resolved!
