Layton ServiceDesk assumes that it will have the port assignment ''80''. If other websites were previously installed on the same server, it's likely that one of them will have been given port 80 and Layton ServiceDesk will be given a different port number, e.g. ''81''. You can check the port assignment using '''[http://msdn.microsoft.com/en-us/library/bb909657(v=vs.90).aspx this article]'''.
