The WinHost is similar in concept to the ihost, however, this one runs on |
| 130 |
|
|
Windows NT/2000 servers. Again, the configuration is dynamically |
| 131 |
|
|
obtained from the server. The WinHost is typically only present in |
| 132 |
|
|
the Windows system tray. Double clicking on the system tray icon |

will bring up a small window that allows data to be viewed and to force |
