Insufficient memory to continue the execution of the program.

Question

I am working on a web page that will display some server statistics on a remote server when requested.  I have this working for 3/4 servers that I am trying to display but the 4th server keeps getting an "Insufficient memory to continue the execution of the program." error as soon as the page starts to load.  The error is occurring at the scope.Connect() line of code. Here's the code:

public void GetDiskspace()
    {
        ConnectionOptions options = new ConnectionOptions();
        //options.Username = ServerName + "\\wwfadmin";
        options.Username = "server4\\id";
        options.Password = "password";       
        ManagementScope scope = new ManagementScope("\\\\server4\\root\\cimv2",options);
        scope.Connect(); // Error is occurring here

        // Check diskspace
        ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
        SelectQuery query1 = new SelectQuery("Select * from Win32_LogicalDisk");

        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
        ManagementObjectCollection queryCollection = searcher.Get();
        ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);
        ManagementObjectCollection queryCollection1 = searcher1.Get();

        // Create DataTable
        DataTable dsDataTable = new DataTable();
        DataColumn dsDataColumn;

        dsDataColumn = new DataColumn();
        dsDataColumn.DataType = Type.GetType("System.String");
        dsDataColumn.ColumnName = "Name";
        dsDataTable.Columns.Add(dsDataColumn);

        dsDataColumn = new DataColumn();
        dsDataColumn.DataType = Type.GetType("System.String");
        dsDataColumn.ColumnName = "Size";
        dsDataTable.Columns.Add(dsDataColumn);

        dsDataColumn = new DataColumn();
        dsDataColumn.DataType = Type.GetType("System.String");
        dsDataColumn.ColumnName = "FreeSpace";
        dsDataTable.Columns.Add(dsDataColumn);

        DataRow row;

        foreach (ManagementObject mo in queryCollection1)
        {
            // Display Logical Disks information
            row = dsDataTable.NewRow();
            row["Name"] = mo["Name"];
            decimal Size = Convert.ToDecimal(mo["Size"]) / 1073741824;
            string strSize = Size.ToString("N2");           
            row["Size"] = strSize;
            decimal FreeSpace = Convert.ToDecimal(mo["FreeSpace"]) / 1073741824;
            string strFreeSpace = FreeSpace.ToString("N2");
            row["FreeSpace"] = strFreeSpace;
            if (Size != 0)
            {
                dsDataTable.Rows.Add(row);
            }       
        }
        this.DiskSpaceGridView.DataSource = dsDataTable.DefaultView;
        this.DiskSpaceGridView.DataBind();
       
    }

I can't think of any reason this code would fail for this one server when it works for 3 other servers without a problem.  The error pops up immediately.  I thought it may be related to the connection, but was able to get into the server using Remote Desktop with the credentials I'm supplying without any issues. 

I'm at a complete loss as to how to solve this.  Can anyone see any reason why this wouldn't work for only one server?

Answer 1

I managed to resolve the issue by deleting a phantom user (It was a people icon with a ? mark.  I've never actually seen it before) in the Remote Desktop Users screen and then rebooting the server.  I suspect this may have been causing a problem with the remote connection; although the error message definitely wasn't pointing that way.  Thanks for your help and suggestions.  You pointed me in the direction of looking at the permissions.

Answer 2

I would still check the permissions on the folders/files you are trying to access through your code.  Check the permissions on a server that is working verses the one that isn't.  Even if you are using Administrator, the permissions could still be off, I know just from experience.  Good Luck

Answer 3

I had thought that might be the issue, too, but the id I'm using to get in is an Administrator.

Answer 4

The only thing I can think of is that there might be some permissions error on that one server.
