String message = ' You did ' not enter a server name. Cancel this operation? ";
String caption = "No Server Name Specified";
MessageBoxButtons buttons = Messageboxbuttons.yesno;
DialogResult result;

result = MessageBox.Show (this, message, caption, buttons,
Messageboxicon.question, Messageboxdefaultbutton.button1,
Messageboxoptions.rightalign);

if (result = = Dialogresult.yes)
{
