"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

They are key shares for Active Directory to replicate important information such as group policies that workstations need access to.

Netlogon and Sysvol are Shares that reside on ALL domain controllers.

Netlogon is the share where LogonScripts are stored and this is access by all users/computers. This is to ensure that if you have computer or user scripts this is where they reside.

Sysvol is the location where group policies reside and ALL computers and users use this directory for retrieving domain policies.

Both directories have Read Access for everyone and this is normal. In order for clients to successfully get the policies and scripts based on Group Policies they need to be able to read the contents of these shares.

If these shares are not accessible for whatever reason your AD environnent will not work, they are critical for initial logon and backgroup policy refreshes.
