Analyzing remote computer's disk space without credentials.

Question

Hello,

I want to know the space available on each drive of remote computer. For that I am using the following code and its working fine.

ConnectionOptions oConn = new ConnectionOptions();
oConn.Username = "username";
oConn.Password = "password";
string strNameSpace = @"\\";

if (srvname != "")
   strNameSpace += srvname;
else
   strNameSpace += ".";

strNameSpace += @"\root\cimv2";

ManagementScope oMs = new ManagementScope(strNameSpace, oConn);

ObjectQuery oQuery = new ObjectQuery("select FreeSpace,Size,Name from Win32_LogicalDisk where DriveType=3");

                
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);

                
ManagementObjectCollection oReturnCollection = oSearcher.Get();

                
foreach (ManagementObject oReturn in oReturnCollection)
{

MessageBox.Show("Drive Name : " + oReturn["Name"].ToString() + 
                                    "\nFree Space =" + (Convert.ToDouble(oReturn["FreeSpace"]) / 1048576) / 1024 + " GB. \nTotal Space = " + (Convert.ToDouble(oReturn["Size"]) / 1048576) / 1024 + " GB.");
                    
                }

Just wanted to know if it is possible to connect to remote computer without specifing the username and password. Want to skip following two statements;

oConn.Username = "username";
oConn.Password = "password";

Is it possible?

Please let me know.

Thanks,

Answer 1

It is only possible if an account is available which does not require logon credentials from a remote connection - you do not want to do this!

As trying to secure the account so that it is limited to only safe operations is very difficult indeed.

You could create a Windows Service on the remote machine which you can remotely ask information from without credentials. This is how I would do it. It is a lot easier to code and control.

Answer 2

you can put the code(.bat/.exe) that calculates local machine's disk space on that remote server in some shared drive and then call/execute it remotely from outside with another code. http://stackoverflow.com/questions/1393711/c-sharp-get-free-disk-space
