c# WMI authentication problem
Hi,
I am attempting a software and hardware inventory over our network, Novell sitting on top of AD (that's about all I know about the network setup). I am using a Windows application with C# and WMI services (.NET 2.0). I can list the services of the local machine with no problems, but I get the following error when trying to authenticate on a remote coomputer with the user as the local Administrator and the matching password. I have tried placing the name of the computer before the username (machinename\Administrator ), but get the same error.
Could not connect to server! Cannot open SCardSvr service on computer 'computername'

Are you using a ManagementScope instance, with connect options for the user name and password?

Yep, here's the code
I think I have discovered that the user used for authentication must have domain admin privileges, where I was using a user that is the Administrator on the local box I was attempting to profile. I don't have these privileges and am looking for a way to just read the data without getting a new user with domain admin rights created for me (corporate red tape). I don't need to install software or get services, just want to inventory the software and hardware, serials, licenses, etc.
Thanks

address = "\\\\" + address + "\\root\\cimv2";
ManagementScope oMs;
if (tbUser.Text != "" && tbPass.Text != "")
{
ConnectionOptions oConn = new ConnectionOptions();
oConn.Username = tbUser.Text;
oConn.Password = tbPass.Text;
oMs = new ManagementScope(address, oConn);
}
else
{
oMs = new ManagementScope(address);
}
ObjectQuery oQuery = new ObjectQuery("select * from Win32_Product");
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);
//Get the results
ManagementObjectCollection oReturnCollection = oSearcher.Get();
Can you run other queries, or do they all fail with the same error?

I can run other (any) queries on my local machine, just not on other machines on the network. I tried to query services (actually not through WMI), disk usage, processor and installed software. All get the same error.
