Script audit of basic events (create/delete user, create/delete group, change membership in group, create computer) in Active Directory.

Security log 32-bit Windows can be no larger than 512 MB. In the 64-bit version of the Security log size increased to 4 GB. So I want to share a script that checks the logs DCs and stores ".csv" file, the following events:
1. user added to a group,
2. user deleted from the group
3. user created,
4. user deleted,
5. group created,
6. group deleted,
7. computer generated

Pre to your computer to install the Active Directory module in PowerShell (http://blogs.msdn.com/b/rkramesh/archive/2012/01/17/how-to-add-active-directory-module-in-powershell-in-windows-7.aspx) And Log Parser 2.2 (http://www.microsoft.com/en-us/download/details.aspx?id=24659). At the beginning of the script you need to specify the domain (in example "contoso.com").
Execution of the script, you can schedule such as every 2 hours.
