I have issue access the admin share on Windows server 2008R2 in the domain environment .
The error message is similar to the below screenshot.
Many people suggest to enable below 2 keys and reboot the computer.
I tried the above approach but does not make much difference.
It turns out that somehow didn’t enable the “File and Printer Sharing for Microsoft Networks” in the network card. After I enable it, the admin share works fine without issue.
