The network path was not found.

I am continuing to get this same message when I load a particular page, which needs to generate a .pdf form.

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.IO.IOException: The network path was not found.

  at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
  at System.IO.Directory.InternalCreateDirectory(String fullPath, String path, DirectorySecurity dirSecurity)
  at System.IO.Directory.CreateDirectory(String path, DirectorySecurity directorySecurity)
  at System.IO.Directory.CreateDirectory(String path)

Could anyone help me here please?
