file explorer crashes after trying to access remote drive

Hi, Jakub

I'm Independent Advisor. I hope it helps.

The following command will do a full scan of the protected system files on your computer and fix any file that are causing issues while Windows 10 is up and running.
1. Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin), as you will need administrator permissions to run SFC.
2. In the Command Prompt type the following command and press Enter:
sfc /scannow
1. Once the scan completes, you will see one of the following messages:
o Windows Resource Protection did not find any integrity violations:This indicates that your system doesn't have any missing or corrupted files.
o Windows Resource Protection could not perform the requested operation: This message means that there was a problem during the scan and an offline scan is required.
o Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log: You will get this message when SFC was able to fix the problem. Now, you can move on or you can view the logs to get more details.
o Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log: In this case, you'll need to repair the corrupted files manually.
Quick Tip: You may want to run the command around three times to fix all the problems.

Hello my name is Bradford and I'm an Independent Advisor for the Microsoft Community and I will try to resolve your problem.

It sounds like your Icon database in Windows is corrupted and has to be rebuilt. In Windows 10 the procedure is a bit long but I've outlined it below for you:

To rebuild the icon cache database on Windows 10, close any application that you may be running, and then do the following:

1. Press Windows Key+R to open the “Run” box.
2. Type “cmd” into the box and then press Ctrl+Shift+Enter to run the command as an administrator.
3. Type the following command to navigate to the icon cache database location and press Enter:

cd %homepath%\AppData\Local\Microsoft\Windows\Explorer

4. Type the following command to verify the icon cache database files are at the location and press Enter:

dir iconcache*

The output of the dir command should list these database files:

iconcache_1280.db
iconcache_16.db
iconcache_1920.db
iconcache_256.db
iconcache_2560.db
iconcache_32.db
iconcache_48.db
iconcache_768.db
iconcache_96.db
iconcache_custom_stream.db
iconcache_exif.db
iconcache_idx.db
iconcache_sr.db
iconcache_wide.db
iconcache_wide_alternate.db

--VERY IMPORTANT about step 5: Once you terminate File Explorer, your desktop background and taskbar will disappear, leaving a black screen — but it's OK, it's only temporarily. You need to close File Explorer to be able to delete the icon cache files. Otherwise, you won't be able to do it.
------

5. Type the following command to stop File Explorer and press Enter:

taskkill /f /im explorer.exe

6. Type the following command to delete the iconcache files and press Enter:

del iconcache*

Note 1: If you get access denied trying to remove the files, you're probably not running Command Prompt with as an administrator. Repeat these steps, but making sure Command Prompt starts with administrative privileges.

7. Type the following command to verify that you successfully deleted the icon cache files and press Enter:

dir iconcache*

Note 2: If you still see some iconcache files, then it's likely that some apps are still running, which will prevent you from deleting the database files. Make sure to close them all, and repeat the steps.

8. Type the following command to start File Explorer and press Enter:

explorer.exe

9. Close Command Prompt to complete the task.

Once you completed the steps, Windows 10 will automatically recreate the database files with fresh icons, this should fix the problem

If following the above steps doesn't resolve the issue please let me know!
