Network: Change Adapter Options – Windows cannot access the specified device, path or file…
Windows cannot access specified device… error is caused by built-in Administrator account, which seems not have proper permissions setup at the time of Active Directory install. This problem only shows up after active directory installed on Windows Server 2016 or 2019 and logged in with DOMAIN\Administrator.
Login DOMAIN\Administrator, open Active Directory Users and Computers, go to Users under your Domain. Right click on built-in Administrator username, select copy and name new administrator account with new username (e.g. ABCadmin), enter your password and save new account. it will create new account in Active Directory with same administrators’ rights as built-in administrator.
Logout and login with new created administrator account, all will work fine.
Or another variant:
Elevated command prompt, run gpedit.msc
Navigate to:
Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options
Enable “User Account Control: Admin Approval Mode for the Built-in Administrator account”
Reboot and try again.
Not sure exactly why, but this fixes the issue for me.
