Hi
I am using WMI management object for checking the status of printer availability. I am generic failure error. My machine is Windows 2003 server. I am attaching the code snippet here

ConnectionOptions objConnection = new ConnectionOptions();
            
string strMachineName = System.Environment.MachineName;
ManagementScope objScope = new ManagementScope(@"\\" + strMachineName + @"\root\cimv2");//, objConnection);
objScope.Connect(); (Getting a generic failure error at this line)
SelectQuery selectQuery = new SelectQuery();
selectQuery.QueryString = "Select * from win32_Printer";
ManagementObjectSearcher MOS = new ManagementObjectSearcher(objScope, selectQuery);
ManagementObjectCollection MOC = MOS.Get();

Best Regards
Surya
