System.Environment.MachineName Exception

[Paul Duncan]

Hi, I'm using the following code to get the Machine name in an app

System.Environment.MachineName

On most computers this works fine but on one of our testers computers
(machine is a windows 2000 desktop pc, not a networking share either),
it's throwing the following exception.

Request for the permission of type
System.Security.Permissions.EnvironmentPermission, mscorlib, Version =
1.0.50000.0, Culture = neutral, publicKeyToken = blahblahblah failed.

I have no idea what is causing this. I tried messing around with the
.Net Configuration. Figured mscorlib didn't have permission rights.
also.........

I can't get any computer information in general. Trying to do some WMI
core queries as well from code and getting a "Security Error" Exception.
Below is the code that gets the disk size.

public string GetsDiskSize(){
ManagementClass cimobject;
ManagementObjectCollection moc;

cimobject = new ManagementClass("Win32_DiskDrive");
moc = cimobject.GetInstances();

try { // BIOS INFO
foreach(ManagementObject mo in moc){
this.m_sDiskSize = GetSystemValue("Size",mo);
mo.Dispose();
break;
}
}
catch(Exception ex){
System.Windows.Forms.MessageBox.Show("GetsDiskSize " + ex.Message);
cimobject.Dispose();
moc.Dispose();
return ex.Message;
}
cimobject.Dispose();
moc.Dispose();
return this.m_sDiskSize;
}
