Known Issues/FAQWindows Terminal Server (WTS)Citrix Metaframe/ICA Protocol |

Closing the window or selecting 'Start Menu->Disconnect' will merely disconnect you, which means that your session is still idled and using systems resources and any opened files you may have. The Citrix load balancing feature occasionally fails to reconnect you to the proper (disconnected) session; creating a new session instead. As a result, this behavior will lead to file locking problems, and you cannot access files left open in your last session. WTS servers are set to disconnect users after 3 hours of idle time (we have limited licenses), so please do not stay logged on when you are not in use, since if you get disconnected while your files are open, you will end up with file locking problems. If a session freezes so that you
cannot properly log off, you should send email to 'wts-admin@slac.stanford.edu''
so that an administrator can log you off or terminate your session
properly. More

Why do we need to worry about the Windows Terminal Server Security?
I'm connecting from a remote site. What is the most secure way to
establish a connection?
Can
I add Printers to the Terminal Server and How I can print from it?
If you are running a full Windows Desktop, make sure to go to the Start button -> Logoff -> OK to end your Windows NT session. If you are running a single application (i.e. MS Word, Excel, PowerPoint, etc.) go to the File menu -> Exit to close the application/session at the same time. Note: If you do not follow this procedure and you just close the Window by clicking the "x" button at the top right corner, you simply disconnect from your session, but have yet to properly logoff. Therefore, you're still using valuable system resources that could be freed up and used by others.
Citrix ICA clients cannot establish connection with the Windows Terminal Server, error 'Cannot connect to the Citrix server: TCP/IP protocol is not available.'In 'Citrix Program Neighborhood' window, press the 'Refresh' button.
If "refresh" works, it usually means that the cached (ICA)
information on the client is either (badly) out of date (points to obsolete
servers/services), or is somehow corrupted and is being misinterpreted, etc.
Citrix ICA clients cannot establish connection with the Windows Terminal Server, error (52E)
Verify that you are connecting to the published application set and not directly to the server. The term "published" means applications that are being offered by the Terminal Server for connection and you can only connect to the specific application you choose. Furthermore, if you choose "User Desktop Full Screen" within the list, you'll get the whole Windows Desktop as opposed to a single application. Please follow the instructions given at Citrix at SLAC for proper client configuration.
Yes, go here to learn how to map your local drives manually from Mac and Windows ICA clients and go here to learn how to mount your home directory (or local file system) from Linux/Unix ICA clients.
AFS
is not implemented on the MetaFrame servers themselves (since this does not
work in multi-user mode on the server). We
You
need to select Start menu -> select Settings -> Control Panel ->
select Mail -> select
Microsoft Exchange -> click on properties -> correct the entry to 'your_exchange_server.slac.stanford.edu'
Look up the exact name for 'your_exchange_server.slac.stanford.edu' on this page.
No. Absolutely not unless you are running an application that will affect the functionality of the ICA client software. Remember that by connecting to the WTS, all applications are running on the server. It is a remote connection. A Server-based computing architecture, sort of a "mainframe" environment if you will.
Please see draft by SLAC Computing Security Officer.
The Windows Terminal Server/Citrix MetaFrame is configured to accept basic ICA encryption level connections. However, if you are coming from a remote site, we strongly encourage you to establish a SLAC VPN * (Virtual Private Network) circuit using Point-to-point Tunneling protocol (PPTP), and then, have your ICA session go through that secured channel.
*Requires NT password
You can add any printer that is included on the installation media for NT 4.0. For the complete list of standard NT printers, click here.
TIP: You can use a printer driver that is "close" to the printer you attempting to use. For example, if you have installed a HP 5Si printer, you can probably use a HP 4si printer driver in a pinch.
NOTE: Users do not need to add drivers if they are connecting to a NT network print queue. All library and printer definition files are transferred automatically from the server acting as a print server to the client system (in this case, the Windows Terminal Server). For instructions on how to connect to a NT print server/queue, click here.
The U drive is a DFS (Distributed File System) that the WTS currently does not understand. Therefore, the U drive does not get mapped when you log on. However, if you are connecting from a Windows NT workstation on site, you can manually map the U drive. Please go here to learn how.
You can use Netscape Messenger as your Email application. Please follow the instructions here to configure it. The current version of Eudora Email does not work well on a multi-user platform like the Terminal Server. You can also use MS Outlook Express or Outlook 2000 if you are a SLAC MS Exchange user.
Users can not write to the WTS local disks. Therefore, you must configure your Netscape Profile so that it points to your home directory (Z drive). Please see the instructions here.
From a "Full Desktop" session, go to the Start button, select Windows NT Security...click on the Change Password... button from the pop up dialog.
Use the following instructions to mount your local volumes.
This error is caused by the Citrix ICA browsing service inability to correctly advertise the list of published applications to the ICA client (Citrix Program Neighborhood) in your local subnet. Please follow the instructions here to configure custom ICA connections to published applications instead of relying on the browsing method.

Warning:
You should always 'logoff' once you finish a
session. Go to the 'Start Menu -> Logoff -> OK'.
