Run System Administration Scripts as Windows Service

Run System Administration Scripts as Windows ServiceVB or JS scripting is a powerful tool used by administrators to automate administrative tasks. Smart, educated administrator can easily manage 30-50 servers without dropping balls if he uses administrative scripting techniques. I would argue that Linux environment is more flexible for administrative scripting then Windows however syntax might be awkward in Unix shell scripting. Digital Edge wanted to introduce this case study to show how to overcome Windows shortage for automating administrative tasks. 

Sometimes Windows system administrators have small tasks that they would like to script as a VBS and have it ran as a service. The example could be a process monitoring or simulating well known WhatsUp functionality. Let's say you have a file with IP addresses that you want to ping and send an email when the IP address is unavailable. It is easy to find a reference on the internet how to implement a VBS or JS script that would allow you to perform this task: 


  • Open file (or maybe a small database);
  • Read entries in an array;
  • Loop through the array and build shell ping command;
  • Receive STDOUT in your script and parse it;
  • Send an email if there is a failure;
  • Delay for a define period of time;
  • Repeat all started from step 3.

Now the best thing for you is to run this as a service. 

So when the server starts up your monitoring would be loaded in the memory. 

There are 2 ways of doing it. 

1. To run the script as a scheduled task. You can create a scheduled task that fires up when system starts up. You can do it through standard create task facilities clicking on Schedule task drop down on the Schedule tab and selecting "At system startup". 2. More elegant way is to run it as a service. 

Windows Resource Kit provides utilities SRVANY and INSTSRV to do that. 
You can reference Microsoft KB #137890 to see how it is done: 
However windows service manager can start only a single executable without parameters. 

You can start an executable like 


But to start VBS you would need to be able to execute something like this: 

cscript.exe c:\admin\foo.vbs 

That cannot be done by service. To do this, you need to wrap the call in something that can be executed. Write a VB or C wrapper that would call your cscript with VBS. You also can use BAT mechanism for that. You can create your foo.bat as this: 

cscript.exe c:\admin\foo.vbs>c:\admin\foo.log 

Now this BAT can be executed by the service manager and you will even have a log file collecting output from your VBS script. So in the registry correspondent to your service you will be calling c:\admin\foo.bat. There is one small problem with this approach. If you open task manager you will not see the process associated with your foo.vbs. All you can see is cscript.vbs. If you have multiple vbs scripts running as service it is hard or impossible to distinguish them. To address this we suggest to copy cscript.exe from \windows\system32 directory to your admin directory and rename it lets say FOO.exe. So the foo.bat file will look like: 

c:\admin\foo.exe c:\admin\foo.vbs>c:\admin\foo.log 

then when you open task manager you can see task foo.exe that represents your foo.vbs running. Lastly, we suggest to use TAIL utility from Windows Resource Kit to monitor you foo.log. Good luck with you administrative scripting.
