On a day to day work, some or the other time you must have come across the situation where you want to extract the reports like the list of disabled users from Active directory, the list of Active mailbox users in your exchange server etc. Most of us will search for some automated tool to extract the reports. But you do not need any such scripts to extract these reports; the CSVDE command will help you in getting the report.

For e.g. you need the report of all enabled user accounts in your domain, use the below command.

Open command prompt and execute it(note – modify the command with your domain details).

CSVDE -r "(objectClass=user)" -d "dc=ExchangeDictionary,DC=com" -s ExchDicDC01.ExchangeDictionary.com -l displayname,useraccountcontrol -f c:\UserList.csv

-r :- this place we will give the filter, here I have given the objectClass=user, so the command will only run against the user objects.

-d :- scoping the command, here I have scoped to the entire domain(dc=ExchangeDictionary,DC=com means the domain ExchangeDictionary.com ). If you want to execute against one OU, you can still do it. Replace this with Ou=”your OU Name”, dc=ExchangeDictionary,DC=com

-s :- specifies the domain controller to which the command to run.

-l :- the list of attribute that needs to be extracted for each matching active directory object.

-f :- the output file.

Once you have succefully run the above command, open the output file in excel. Now you may verify the useraccountcontrol value against the below list and filter out the required report.

UserAccountControl Values

512 - Enable Account

514 - Disable account

544 - Account Enabled - Require user to change password at first logon

4096 - Workstation/server

66048 - Enabled, password never expires

66050 - Disabled, password never expires

66080 – Enables, password never expires, password not required.

532480 - Domain controller

590336 – Enabled, User Cannot Change Password, Password Never Expires

We can view and edit these attributes by using either the Ldp.exe tool or the Adsiedit.msc snap-in. Ldp.exe shows the values in hexadecimal. Adsiedit.msc displays the values in decimal. The flags are cumulative. To disable a user's account, set the UserAccountControl attribute to 0x0202 (0x002 + 0x0200). In decimal, this is 514 (2 + 512).

See the property tag and the corresponding value in decimal
