2013 – "Open in Explorer" fails despite some common fixes

I have an extranet solution in SharePoint 2013 running on Windows Server 2012 r2. When I try to use the "Open in Explorer" command in a SharePoint document library, I get the following message:

"We have a problem opening this location in File Explorer and add this site to your list of trusted sites and try again."

First some more detailed information about my setup:

-This is a development server, so everything runs on the same machine.

-I am logged into the development server with an account that has all permissions under the sun.

– May be related – I also can not reach any of my sites through mapping network drives ("Add Network Location" via Explorer).

Below is a complete list of things I've already tried after over a week of research, trial and error:

browser:

-Using 32-bit Internet Explorer (I understand that Chrome, Firefox, Edge, and 64-bit IE can not use the "Open with Explorer" option).

-All my sites have been added to the Trusted Sites list in 32-bit IE.

– You also tried to add them to the intranet zone with identical settings.

-Activates all commonly recommended ActiveX controls / add-ons / etc in IE.

-Use the Emulation tab in the IE11 developer tools to emulate the IE10.

-All sites have been added to the Compatibility View in IE11.

Between each attempt, the cache was flushed in IE (ie after I changed something, including those listed below).

SharePoint:

-Checked alternative access mappings according to (https://goo.gl/kkbyXb).

-Checked managed paths according to (https://goo.gl/1TErTM).

The website application in question uses Integrated Windows Authentication (NTLM). Basic authentication is also enabled.

Client integration is enabled for this web application.

-The account I use has full access to all the resources in question.

Windows

-WebDAV is installed / running.

The WebClient will be installed / run (including Desktop Experience).

Registry changes (WebClient parameter – BasicAuthLevel to "2", AuthForwardServerList, which includes all my sites).

– User Account Control set to low, then disabled.

– Installs any recommended updates / hotfixes that are remotely applicable to the problem.

Other potentially useful information

Until I enabled the "Automatically log in with current user credentials" option in IE, the "Open with explorer" button prompted for credentials before the above error message was displayed.

I used Fiddler to see what happened when I clicked Open with Explorer. That probably only confused me. When attempting to open the library in the Explorer view, the error message "401 UNAUTHORIZED" is displayed. This is almost useful if the button for entering credentials has been requested. However, the question arises: If my credentials do not exist, what is being searched for?

tl; dr

I've tried every solution I could get my hands on after I've dealt extensively with the subject. I divide them up logically, not chronologically, but meanwhile I've tried every possible variant of the above solutions that I can imagine to make any difference.

The goal here is actually to retrieve the path of a document within the library and pass it to an Excel connection manager in an SSIS package. I mention that because at this point I'm ready to try a workaround, if any.

Sharepoint – "Open in Explorer" does not work

This is a SharePoint 2016 system. No matter in which library, clicking on "Open with Explorer" will do nothing – no errors, no action. This is a problem for all users (IE11 on Win10, mostly, but also on Win8.1, Server 2012/2008).

If we copy the address bar of the browser and paste it into File Explorer, it works, at least we have a workaround, but then re-authentication is required.

It does not work with a clean SharePoint test system, but at least we get the following:

This test system has not yet seen a patch, so "it turns out a little less".

The usual suspects were brought to justice:

Command Line – How can I associate a file type in Windows 10 if the right-click "Open With" is not an option?

In Windows 10, I found that I could not run .bat files because they were associated with notepad ++ and therefore opened by default for editing.
Normally, I would fix this by right-clicking, selecting "Open With," selecting the application, and selecting "Set as Default." This option was not available.

Trying to update the file type associated with CMD did not work either. Selecting the default application by file type only gave me the ability to download an app from the Microsoft App Store.

From here (method 5) I found a command line option

Open a command prompt with a raised cmd

ftype>% UserProfile%  outputAssociations.txt

This will create a list of all current mappings as a TXT file in the base folder of the current user. I searched outputAssociations.txt and could not find anything with .bat. Odd.

My solution

cmd (execute as administrator)

ftype batch = c:  windows  system32  cmd.exe "% 1"
assoc {.bat} = {batch}

.bat files are now executed in CMD and not opened with Notepad ++.

2010 – How to set links by default to "Open in new tab"?

If I set a link in my test to open in a new tab with "Open in new tab" and save the page, the link will open when you click on the link in a new tab.

Make sure you've selected the link for your issue and set it to "Open in New Tab."

Also, my SharePoint 2010 is 14.0.7175.5000. You can check your build number of your SharePoint 2010 farm.
