Below is the code in vbscript. The problem is, GetObject, startService, and ExecuteQuery commands may get errors because of various reasons. For example, after issuing "stopService" command, the state of the service may become "stopping", instead of "stopped", and the script is hanging there for quite some http://stackoverflow.com/questions/5413591/how-to-catch-wmi-errors time. Sometimes, error messages such as "RPC is not available" was returned. Seems there is no catch exception machanism built into vbscript. Most of the examples I saw online never considered such situation. Does anybody know there is a good way to catch such kind of errors, and force these command (note: not service itself) to abort?

Solved VBScript hanging on WMI Query dispite error handling Posted on 2011-12-28 VB Script Windows Server 2003 1 Verified error handling Solution 7 Comments 1,910 Views Last Modified: 2012-05-12 I have a script that is very long that is hanging upon a WMI query to a particular host. Rather then trying to fix the orginal script I created this small snippet to test my code. This code hangs for several hours until I kill the process. Just a note it works on all other servers just vbscript on error fine. I can also remote into, and manage remotely this server through windows tools. I should also not that it is line 3 that creates the issues as I have added msgbox outputs to see where the hanging begins. It is not my desire to fix the problematic server, rather to correct the script to handle this situation.
