Remote WMI Connection issue

[sansircar]

i needed to get the free disk space on a shared remote drive.
my shared-name goes something like this -- \\RemoteServer\ADrive$

ConnectionOptions oConn = new ConnectionOptions();
oConn.Username = "xUser";
oConn.Password = "xxxx";
string sSrvName = @" \\RemoteServer\ADrive$";

ManagementScope oMS = new ManagementScope(sSrvName, oConn);

I get the error - "Invalid Parameter".
If i remove the $ sign from the end of the server name and make it something like \\RemoteServer\ADrive
it goes past the above statement and fails at
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMS, oQuery) ;
ManagementObjectCollection oReturnCollection = oSearcher.Get() ;

with the error - "RPC server is unavailable"

but when trying to map the above mentioned share drive - \\RemoteServer\ADrive$, via Windows Explorer it works.
any kind of help is appreciated.

thanks to all

Hi,

Your code looks ok, but what's included in your Object Query parameter oQuery?
Have you tried some simple query, like what's mentioned in ManagementObjectSearcher Constructor (ManagementScope, ObjectQuery) ?
