Able to create folder in DC2 but cannot create folder in DC1

Hi All

I setup DC1 in new root forest domain. Then continue setup DC2 as ADC. I've the privileges of Enterprise Admin and Domain Admin.

Problem is:

After logged in to DC1, i cannot create folder in \\DC1\Netlogon. And the option to create files in \\DC1\Netlogon is missing.

Or even C:\Windows\SYSVOL\Sysvol\domain\Scripts

But when trying to create folders/files in \DC2\Netlogon, I'm able to do it.

Does anyone have any idea about this ?
