Explorer view fails: Your client does not support opening this list with Windows explorer


We are unable to browse our sharepoint server in "Explorer view". The clients keep getting an error saying "Your client does not support opening this list with Windows Explorer".

I have tested against another server outside our network, and when I select "Explorer view" there I get no error - the explorer window pops up after a few seconds. This means there's something wrong with my server config?

Server OS: Windows Server 2008 Standard R2 x64
MOSS: 2007 SP2
Client OS: Windows 7 Enterprise x86
Browser: Internet Explorer 8

  1. Click Start
   2. Click Run (if you are using Vista and have Aero interface turned on this is the same as the search bar)
   3. Type in Services.msc and hit enter
   4. In the services window scroll down to the WebClient Service
   5. Right click on the service and choose START
   6. Once it has started go back to your SharePoint window and choose the Explorer View again
   7. It should work!

That's what I though as well - but the service is already started. Tried rebooting both clients and server, and as I mentioned the explorer view works properly on a different sharepoint server...

Thanks for your suggestion thought...

Found the error:

WebDAV was installed in IIS7 - which seems to be incompatible with MOSS 2007. Removing the WebDAV feature and restarting the server solved the problem.

I have the same problem with similar underlying configuration.

WebDav appears not to be installed.....it is not in the list of Role Services under Web Server

  • Sharepoint Explorer View does not work when using IE8 x65.
  • Sharepoint Explorer View does not work  when trying to open a documents list when the Sharepoint site is exposed through/in Outlook 2007.
  • Sharepoint Explorer View does work  when using IE8 x86.
I have done / checked all of these



Additional guidance greatly appreciated.

I was trying to access a SharePoint library in Explorer View on a Windows Small Business Server 2011 and adding the "desktop experience" resolved my issue.


Thanks KFlorian!

We also ran into this issue on users that had installed a new citrix client.  (As part of hardening the system... There are other installations that do this too)  The installer removed the Network provider in the order of opening:  "Webclient" was removed from the REG_SZ:  HKLM\System\CurrentControlSet\Control\NetworkProvider\Order\ProviderOrder
