Simplified configuration

If you find the config panel a bit overhelming and you don't use all the available configuration, you can disable the advanced configuration in the "Server" tab at the bottom of the page.

Create customized setups using OCS Packager

In the case you need to install an agent with pre-provisioned configuration, you can use the OCS Packager to create a customized setup of the agent.

To create the “ocspackage.exe” file, run the OCS Inventory NG Packager and fill in the following informations:

  • Path to file “OcsAgentSetup.exe”, the OCS Inventory NG service Agent installer, included in the package
  • Path to the Certificate file, for checking the server certificate when using the package deployment feature.
  • Optionally, another file to include in the setup.
  • Command line parameters for running “OcsAgentSetup.exe” service installer. At the minimum both “/S” to run the installer in silent mode and “/SERVER:my_ocs_com_server_address” to specify “my_ocs_com_server” the address of the OCS Inventory NG Communication Server.
  • Username (account@domain for Active Directory account and domain\account for a NT4 account) and password of an Administrator account on client computers. “OcsAgentSetup.exe” will be run under this account on client computers, to allow installing service even if user connected does not have Administrator privileges.

Note: Refer to OCS Inventory NG Packager documentation for more informations on how to use Packager.

This will create the file “ocspackage.exe”. If you want to store it, OCS Inventory include a package file upload into Administration console. Click on toolbar Config menu.

Toolbar Config Menu

Click [ Agent ] toolbar menu, browse your hard drive to select agent file and click [ Send ] button.

Add agent

Note: If you encounter error while uploading agent, refer to common errors PHP max post size and MySql upload size

Using Registry Query feature

OCS Inventory NG agent for Windows is able to query the registry of inventoried computers for a value of a key or for all values of a key under registry hives HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS, HKEY_CURRENT_CONFIG (and HKEY_DYN_DATA for Windows 9X based computers).

Enable query registry feature

You have to enable this feature in the general settings REGISTRY.

Registry config

Display/modify/delete an existant request

Click on the toolbar Manage menu then to registry.

Registry manage access

You can display registry queries in central table. Clicking on pencil, you can modify a request. You can delete a request clicking on red cross.

Registry manage

Create a new registry request

Warning: Since OCS Inventory NG 2.0, you do not have to double backslash in the path of the hive.

Click Add button to add a new query. Enter a name for this query, for example PDFCreator Version if you want to retrieve version number, select the registry hive (HKEY_LOCAL_MACHINE in this example), enter the registry key (SOFTWARE\PDFCreator\program) and the value name to query (ApplicationVersion) and validate.

Note: Put star (*) in field “Name of the key” to get all values of the key (This is useful to get all values of key “HKLM\Software\Microsoft\Windows\CurrentVersion\Run” to know which process are automatically started for example).

Add Registry

After that, each time a Windows client will make an inventory, it will retrieve and store all the values corresponding to these keys.

Managing duplicates computers

OCS Inventory NG is able to detect a renamed computer, reinstalled computer…

Generally, it will handle that alone. But sometimes, it is impossible for the server to know whether two computers are the same or not, for example when it has no network adapter (no Mac address) or when the serial number was not properly set by the constructor (If you change a computer’s name, the application won’t be able to recognize it if it has no serial or no Mac address, and thus a duplicate fake computer may be created).

This page accessible by clicking Manage toolbar menu then Duplicates is used to solve this problem.

Access duplicates

Duplicates page You may choose the kind of comparison you want in the top right combo-box.

  • Redundancy summary – Shows the number of redundant computers detected with each comparison method.
  • “Hostname + Serial number”, “Hostname + Mac address”, “Mac address + Serial number” - These are the two criteria comparison methods, the more reliable. It returns all computers that have two criteria in common.
  • “Hostname only”, “Serial only”, “Mac address only” - These are the one criterion comparison methods; it only shows all computers that shares one parameter.

Once computers are shown, it’s up to you to check whether several computers are redundant or not.

Duplicates Redundancy

After that, you only have to select (checkbox) computers that look the same, and click “merge redundant computers”: all the data from checked computers will be merged.

The administrative data of the oldest computer are kept on the merged device.

Note: When those filters are applied, some values are filtered out (For example: 'NNNNNNN' or 'xxxxxxxxxxx' for serial number).

Editing administrative information

OCS Inventory NG allows you to store custom information for each inventoried computers. For example, you can add administrative information to specify the owner of the computer, or the location of the computer.

This administrative information is stored both on the server and on the client to avoid any loss of data.

For example, if the database is lost, all clients will come back with their administrative information.

You can define the administrative information you want for each computer by clicking Manage toolbar menu and then Administrative Data.

Access Administrative Data

Administrative Data

You can add new administrative information definition by entering their name (space or special characters are not allowed) and selecting their type. You can choose type between:

  • Text
  • Textarea
  • Select
  • Checkbox
  • Radiobutton
  • Date

To delete an administrative information definition, just click on red cross at the end of the corresponding line. For example, we will add administrative information corresponding to the buy date of computer.

New Data

You can now browse all your computers to set the buy date for each.

Editing the label

If the DEPLOY option is activated, clients may get the label file. It is used to fill the popup shown on first start of a client.

This popup asks for the TAG value that is used to class computers (it may be, for example, a unit code, the name of one of your company’s section, a street number, etc). This label file is generated during the server install, and may be edited by clicking on Label sub-menu of Config menu intoolbar.

Label Access

If you submit a blank label, the label file will be deleted, and no window will be displayed anymore on client’s computer.

Importing inventory for non network connected computers

With Administration server through your web browser

For non network connected computers, you can import inventory results from a file created on the computer by the agent run in local mode (see § 3.2 We have chosen to package OCS inventory NG server for Windows as an integrated package containing all required components. As is, the 3 main components of Management server (database server, web communication server and web administration server) are installed on the same computer.). We assume that you’re able to save this file in your hard disk from your mailbox, or any other way.

Note: If Communication Server is not running on standard HTTP port 80, or on the same computer as Administration console, you must update General Options. See § 6.2 Managing OCS Inventory NG general options.

Click Manage toolbar menu and then local import, browse your hard drive to select the ".ocs" file or ".xml" file created by agent release and click [ Send ] button.

Local Import

Local Import

With Communication server through a Perl script

Communication server provides the ability to import inventory from a file created on the computer. This file has “.ocs” extension.

We assume that administrator can get the file from somewhere, his mailbox, a USB drive or any other place.

All of our tools are available at the following URL : They are also present in the ocs inventory setup if you still have it on your server.

To import the computer you need to run the script “” with path to file which contains inventory results as argument.

This will import inventory results into the database.

[root@l16753101aao ocsinventory-NG]# ST32491DL-2005-06-23-10-04-02.ocs
OK for ST32491DL-2005-06-23-10-04-02.ocs
Successly inventoried : 1''
Errors : 0

If you have multiple files to import, you can put them in a directory and them launch the script “” without argument, but within the directory where resides files to import.
