1. Verify SRV Resource Records
After AD is installed, the DC will register SRV records in DNS when it restarts. We can
check this using DNS MMC or nslookup command.
Using MMC
If the SRV records are registered, the following folders will be there in the domain
folder in Forward Lookup Zone.

• msdes
• sites
• tcp
• adp

Using nslookup
>nslookup
>ls –t SRV Domain
If the SRV records are properly created, they will be listed.

2. Verifying SYSVOL
If SYSVOL folder is not properly created data stores in SYSVOL such are scripts, GPO,
etc will not be replicated between DCs.
First verify the following folder structure is created in SYSVOL
Domain
Staging
Staging areas
Sysvol
Then verify necessary shares are created.
>net share
It should show two shares, NETLOGON and SYSVOL

3. Verifying Database and Log files
Make sure that the following files are there at %systemroot%ntds
Ntds.dit, Edb.*, Res*.log 

The Active Directory schema is the set of definitions that defines the kinds of objects, and the
types of information about those objects, that can be stored in Active Directory. The
definitions are themselves stored as objects so that Active Directory can manage the schema
objects with the same object management operations used for managing the rest of the
objects in the directory.
There are two types of definitions in the schema: attributes and classes. Attributes and
classes are also referred to as schema objects or metadata.
Attributes are defined separately from classes. Each attribute is defined only once and can be
used in multiple classes. For example, the Description attribute is used in many classes, but is
defined once in the schema, assuring consistency.
