AD it just another database, just like SQL server is. With that in mind there is nothing stopping you from using SQL to link to AD to give you data about your AD environment!

1) Create Linked Server using SSMS

exec master.dbo.sp_addlinkedserver 'ADSI', 'Active Directory Service Interfaces', 'ADSDSOObject', '<DC Name FQDN>'

2) Modify the security for ADSI using SSMS

exec master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N'ADSI', @locallogin = NULL , @useself = N'False', @rmtuser = N'<Domian>\<User Id>', @rmtpassword = N'<Password>'

3) The hard part is over!

4) Create query to query AD and ConfigMgr

This query will list all PCs within AD that are NOT within ConfigMgr (or SMS)

select

AD.cn as 'PC Name(AD)',

AD.operatingSystem as 'OS (AD)',

AD.operatingSystemServicePack as 'SP (AD)'

from

openquery (ADSI,

'SELECT cn,

operatingSystem,

operatingSystemServicePack

FROM ''LDAP://<DC Name FQDN>''

WHERE objectCategory = ''Computer''') as AD

Where

AD.cn not in (Select name0 from v_GS_Computer_System as CS)

order by

AD.cn,

AD.operatingSystem,

AD.operatingSystemServicePack

This query will give you a count of all OS that are NOT within ConfigMgr (or SMS)

select

AD.operatingSystem as 'OS (AD)',

count(AD.operatingSystem)

from

openquery (ADSI,

'SELECT cn,

operatingSystem,

operatingSystemServicePack

FROM ''LDAP://gartek-dc.gartek.tst''

WHERE objectCategory = ''Computer''') as AD

Where

AD.cn not in (Select name0 from v_GS_Computer_System as CS)

Group by

AD.operatingSystem

order by

AD.operatingSystem

So what does this report look like.

So there you have it.
