45. How to find the 'PSO Applies to'
i)dsget user <user DN> -effectivepso

Example:

effectivepso
"CN=test,CN=Password Settings Container,CN=System,DC=contoso,DC=com"
dsget succeeded
("bshwjt" is the user and test is the "PSO" also see the below snap)

ii) How to find the PSO settings
C:\>dsquery * "<CN=your pso name>,CN=Password Settings Container,CN=System,DC=contoso,DC=com" -scope base -attr *

46. Find out Account Expiry date

dsquery user -name * -limit 0 | dsget user -samid -acctexpires

47.This example displays all attributes of the contoso.com domain object
dsquery * -filter (dc=contoso) -attr *

48.This complex example displays the names of all attributes (150) that Windows Server 2003 replicates to Global Catalog servers. (If the command displays no attributes, ensure that you typed TRUE in capital letters
>dsquery * cn=Schema,cn=Configuration,dc=contoso,dc=com -filter "(&(objectCategory=attributeSchema)(isMemberOfPartialAttributeSet=TRUE))" -limit 0 -attr name

49. How to get all samaacount name ?
dsquery user -o rdn -limit 0

50.The command displays the DNS host name, the site name, and whether the server is Global Catalog (GC) server for each domain controller
dsquery server | dsget server -dnsname -site -isgc

Get all the servers in the forest

dsquery server -forest -limit 0 | dsget server -dnsname -site -isgc

51.The dsget command displays properties of users or other objects. In this example, it displays the 6 groups that explicitly list the Administrator as member

Note: The -memberof -expand combination recursively expands the list of groups of which the user is a member. In this example, the Users group is added to the list because Domain Users is a member of the Users group.
dsget user cn=Administrator,cn=Users,dc=contoso,dc=com -memberof

52.The output of the dsquery command can be used as input for the dsget command by using a pipe ( | ). In this example, the SAM account name and the security ID (SID) of each user is displayed.
dsquery user | dsget user -samid -sid -limit 0 >> c:\Allusers-samid-sid.txt

53. How to find RODC ?

dsquery server -isreadonly

Dsqury for exchange server

54. How to find the Schema Version for Exchange Servers.

dsquery * CN=ms-Exch-Schema-Version-Pt,cn=schema,cn=configuration,dc=domain,dc=local -scope base -attr rangeUpper

55.How to find lastLogonTimestamp for all users for a domain

dsquery * -filter "&(objectClass=person)(objectCategory=user)" -attr cn lastLogonTimestamp -limit 0

56. Inactive users are go to disable state

dsquery * <ou> -filter "(&(objectCategory=Person)(objectClass=User)(!accountExpires=0)(!accountExpires=9223372036854775807))" | dsmod user -disabled yes

57.ADDS existing connection point objects 
 dsquery * forestroot -filter (objectclass=serviceconnectionpoint)



58. Find all Hyper-V hosts in your forest

C:\>dsquery * forestroot -filter "&(cn=Microsoft Hyper-V)(objectCategory=serviceconnectionpoint)" -attr servicebindinginformation >> c:\hyper-v.txt
59. Find all windows virtual machine in your forest

C:\>dsquery * forestroot -filter "&(cn=windows virtual machine)(objectCategory=serviceconnectionpoint)" -limit 0 -attr * >> c:\allvirtualPCs.txt
 
60.Extract the all groups from an OU with Group Scope & Group Type. Find the below snap for your reference.
C:\>dsquery group "ou=test,dc=gs,dc=com" -limit 0 | dsget group -samid -scope -secgrp
 
61.The below example displays a list of users from the OU "Customer Support", 
can then be forwarded to dsget that can provide detailed information about objects.
In the example, the requested user list is headed by the pipe symbol after dsget that 
-outputs then the sAMAccountName for all users and email address. 
If we wanted to carry out modifications to the information returned by DSQuery user list, 
we could send the result to dsmod, which for us is making changes to all users. 
In below snap shows the change in the command ensures that all users of DSQuery 
-user list must change their passwords at next logon.
Another way to get the user attributes from an OU. Find the below snap & dsquery for that.
C:\>dsquery * "ou=test,DC=contoso,DC=com" -filter "(&(objectcategory=person)(objectclass=user))" -limit 0 
-attr samaccountname description department title

62.retrieve the DN of all users in the domain that are not direct members of a specified group
>>dsquery * -filter "(&(objectCategory=person)(objectClass=user)(!(memberOf=Groupname,ou=West,
dc=Contoso,dc=com))) -limit 0 > NotInGroup.txt

64. How to find the DNS servers from DomainDNSZones & ForestDNSzones
C:\>dsquery * DC=DomainDnsZones,DC=contoso,DC=com -scope base -attr msDs-masteredBy 
C:\>dsquery * DC=forestDnsZones,DC=contoso,DC=com -scope base -attr msDs-masteredBy

65.Finding the Functional Levels of Active Directory
dsquery * "DC=contoso,DC=com" -scope base -attr msDS-Behavior-Version ntMixedDomain
0, 0        Windows 2000 Native domain Level
0, 1        Windows 2000 Mixed domain Level
2, 0        Windows 2003 Domain Level
3, 0        Windows 2008 Domain Level
4, 0        Windows 2008 R2 Domain Level
66. Find the object for DES-Only-Encryption



dsquery * -filter "(UserAccountControl:1.2.840.113556.1.4.803:=2097152)"

67. Find the DNS servers from all the DNS partitions.



dsquery * "CN=Configuration,DC=contoso,DC=com" -filter "(&(objectClass=crossRef)(objectCategory=crossRef)(systemFlags=5))" -attr NcName msDS-NC-Replica-Locations
