I do not have servers in my home network so in order to simulate one I have created a very simple input list of servers in a text file just copying the localhost value several times.

This approach is my preferred choice and it takes a little bit longer time to write the code but gives us more flexibility and reusability in the long run. This project is the library of different CmdLets that can help us IT personal to do our everyday tasks more efficiently and accurately. Source code for Test-ServerConnection CmdLet can be downloaded from this zip file so please feel free to download it and it would be easier for you to follow me along.

Once again the key to the solution is to think in terms of objects. However, you can also create your own objects. Like string handling, there are multiple ways to create an object. For now, though, I will show you how to create an object explicitly. Once you get the hang of it, you can use some of the other methods of creating objects that use less verbiage.

It was explicitly created above. Additionally, if you run:. Array , even though you created them using different syntax. You may find yourself using the. GetType method often to keep track of what type of objects you are working with. You now have an object that provides more than simply the name of a server. You can add more properties if you want, but the ones here are enough for moving forward. This output is not ideal.

With some effort, you could get rid of the header information, but then you might face other issues. For example what if your Environment for another server is called Dev and QA.
