WMI ManagementObjectSearcher Options
Posted on 2004-08-26
I'm running WMI queries on several machines on our network. What I am finding is that although a group of machines (same make, model, hardware, software platform) are physically located the same distance from me, and are plugged into the same switch, I'm getting large differences in the return time of the following query:
SELECT * FROM Win32_OperatingSystem
I generally get results in roughly 6 seconds, but sometimes the result return takes 1min+ . I'm trying to figure out if I can just force a timeout on a query using the Options property of the ManagementObjectSearcher class, but I'm not sure what options can be set here. Does anyone have any other thoughts why the delays may occur? It's not always the same delay length or from the same computers. It seems like it just randomly pauses. Our network usage hovers at a low 2%, and collisions are little to none, so I'm sure it's not a network issue. The TimeOut property of the Connection class doesn't work, cause I connect just fine, its the call to ManagementObjectSearcher.Get() that causes the delay. Thanks!
