There are many devices servers, desktops, laptops, tablets, phones, etc running a Windows operating system.
Many of us who live in the nix based world have to work in this OS, or if we don't, we will, sooner or later. In this article, we will address the questions like: We will have some minimal sample codes to go through the basic programming techniques. Three keywords here are: Web-Based, management information, enterprise environment.
So if our managed IT environment is a large scale, Windows-based architecture and we want to retrieve management information of each individual node and present it in a web fashion, we will be required to interact with WMI.
WMI is also capable of doing other things like spawning a process in a remote PC but that will be beyond the scope of this article. WMI provides the comprehensive knowledge of a machine, both hardware and software.
It also provides several programming interfaces to retrieve said information.
But in our case, it will be PHP. One of the fundamental questions when programming with WMI is: Luckily, Microsoft provides a full list of what WMI offers in terms of classes and their properties.
Please visit here for a complete reference. We can verify that that is the case through the following two steps: Launch "Computer Management" in your Windows machine and see if the service called "Windows Management Instrumentation" is running.
If not, start that service. Launch "wbemtest" in your Command Prompt window. A dialog titled "Windows Management Instrumentation Test" will appear.
A lot of the buttons in that dialog are currently disabled but we can click the "Connect Normally, we don't need to change a thing.
Just click the "Connect" button in this dialog. It will bring us back to the previous window with all the buttons enabled. Being able to connect to a machine's WMI interface is just one of the pre-requisites.
Please see the screenshots below. After we enable the WMI firewall rules in a remote machine, we can test the connection as illustrated in Step 2 above. Add one line to the php. And, of course, the machines that we will manage via WMI all need to be Windows based.
A further look of what WMI provides Having done all the necessary preparation, and before we start programming WMI with PHP, we really need to get back to the fundamental question we raised earlier: What "information" is available?
But how is this information presented? Besides digging into the official documents provided, let's bring up the wbemtest dialog again and connect to our local machine.Windows’ built-in firewall hides the ability to create powerful firewall rules. Block programs from accessing the Internet, use a whitelist to control network access, restrict traffic to specific ports and IP addresses, and more – all without installing another firewall.
The firewall includes. In Windows Firewall, choose "Advanced Settings" then enable both inbound and outbound access rules for WMI related entries. Please see the screenshots below. Please see the screenshots below. If I try to access the site though chrome I get the error: ERR_CONNECTION_TIMED_OUT.
With the firewall on i'm never seeing any "hits" come through to the app at all. Is there some other configuration I'm missing? Many thanks. Aug 18, · Windows Firewall has been in Windows XP since it was released. With Service Pack 2, Microsoft has shined the spotlight on the firewall as a key .
Windows Firewall with Advanced Security also provides IPsec-based computer-to-computer connection security which allows you to protect your network data by setting rules that require authentication, integrity checking, or encryption when your computers exchange data. Windows Vista improved the firewall to address a number of concerns around the flexibility of Windows Firewall in a corporate environment: The firewall is based on the Windows Filtering Platform.
A new management console snap-in named Windows Firewall with Advanced Security which provides access to many advanced options, and enables remote administration.
