Printers That Use Ports That Do Not Begin With COM, LPT, or USB Are Not Redirected in a Remote Desktop or Terminal Services Session

If you try to connect to a terminal server and have setup local Printer Redirection this might not work on some USB Printers will not be redirected. This is due to a filter on redirection that only redirects ports beginning with LPT, COM or USB. This filter can be turned of.

Setting Terminal Server in Installation Mode

When installing applications on a Terminal Server it needs to be in installation mode. This can be done in one of two ways:

1) GUI

   Goto Control Panel
   Start Add/Remove Programs
   Click Add New Programs and click CD or Floppy

   The terminal Server will den put itself in Installation mode

2) Command Line

   Enter installation mode: Change User /install

   Exit Installation mode: Change user /execute

The terminal services client has been disconnected because its temporary license has expired.

Error: The terminal services client <client> has been disconnected because its temporary license has expired. 


This problem may occur if the Licensing Mode in Terminal Services is set to Per Device, the Terminal Server Licensing server only has Per User CALS.

To correct this problem, change the Licensing Mode in Terminal Services Configuration to Per User. To do this, follow these steps:

1. Click Start, point to Administrative Tools, and then click Terminal Services Configuration.
2. Click Server Settings, and then double-click Licensing Mode.
3. Change the Licensing Mode to Per User, and then click OK.

Currently, Window Server 2003 does not manage User CALs. This means that even though there is a User CAL in the license server database, the User CAL will not be decremented when it is used. This does not remove administrators from End User License Agreement (EULA) requirements to have a valid terminal server (TS) CAL for each user. Failure to have a User CAL for each user, if Device CALs are not being used, is a violation of the EULA. In the future, this behavior will be changed and User CALs will be managed.

The following text is from the End User License Agreement (EULA) for Windows Server 2003:

Two different TS CALs are available to you: “Device” and “User.” Each TS Device CAL permits one Device (used by any User) to conduct Windows Sessions on any of your Servers. Each TS User CAL permits one User (using any Device) to conduct Windows Sessions on any of your Servers. You may use a mix of TS Device CALs and TS User CALs simultaneously with the Server Software in your environment. You can have a Terminal Server request Per User licenses or Per Device (default) but not both simultaneously.

Problem vid uppkoppling till Citrix nFuse: Error:ICA file not found

Users may receive the following error message when launching published applications through NFuse:

“ICA File Not Found”

user posted image

The following scenarios are known to produce this error message:

The Web pages were presented with the HTTPS protocol and the client cannot save encrypted pages to disk.

    When a user clicks an application icon, the Launch.ica file is downloaded from the Web server and then executed by the local client. If the NFuse Web server is using SSL (https://…) and your browser is configured so it does not save encrypted pages to disk, the Launch.ica file cannot be written to disk and the client has no file to open.

To resolve this issue:

    A. On the client device, in Internet Explorer, go to Tools > Internet Options.

Select the Advanced tab.

Beneath the Security section of options, clear the option called Do Not save encrypted pages to disk.

Excessive internet cache

    On Windows computers with large hard drives, the Temporary Internet Files folder used by Internet Explorer can become excessively large, causing too much of a delay in the time required to save the Launch.ica file and then retrieve it for use by the client.

To resolve this isue, clear the browser cache:

In Internet Explorer select Tools > Internet Options.

Select the General tab.

In the Temporary Internet files section of options, click Delete Files.

Note: You may also want to click Settings to decrease the amount of disk space to use for the Internet cache.

From the MSconfig/General tab, choose selective start option, clear load startup items, and click Apply. Restart the system.

Accessing through NFuse Version 1.6

You can launch applications only once.

Additional Information

When users access the Internet, certain applications (for example, Gator, download accelerators, and so on) are installed on the users’ systems without acknowledgement. The problem occurs on Windows clients Windows 9x, XP, or Me.
