The NETLOGON share on the %LOGONSERVER% is used to store the logon script, and possibly other files.

When a user has a logon script configured, it is generally specified without any path, as in logon.bat.

To locate the NETLOGON share on a domain controller:

1. Log on to the console of the domain controller.

2. Open a CMD.EXE prompt.

3. Type net share netlogon and press Enter.

4. You will receive a display similar to the following:

Share name        NETLOGON
Path              C:\WINDOWS\sysvol\sysvol\JSIINC.COM\SCRIPTS
Remark            Logon server share
Maximum users     No limit
Users
Caching           Manual caching of documents
Permission        Everyone, READ
                  BUILTIN\Administrators, FULL
The command completed successfully. NOTE: The default location of the NETLOGON share on a domain controller is:

%SystemRoot%\sysvol\sysvol\<DomainName>\scripts
