You might experience the following issue with the Windows 2008 R2 Server.
When you try to access the server using UNC path, you might get the following error:
Error code 0x80070043 – The Network name cannot be found
Also, when you try to view the local shares using \\localhost command, you get the same error message.
Solution:
Install the KB2194664 hotfix in elevated mode (run as administrator) because you might have issues with the installation if not installed with admin permissions.
If you still have issues, please post below and I’ll try to help.
