Known Issues in this Release

The following is a list of known issues in this release. Read it carefully before installing the product.

• Setting up pass-through with smart card authentication
• ICA file saves to disk during client launch
• Error message when attempting to connect using clients prior to Version 6.20
• Native client cannot be upgraded on devices running Windows XP Embedded

Setting up pass-through with smart card authentication

Users who log on to a site configured for pass-through with smart card authentication using explicit credentials are presented with a Welcome to Windows dialog box when launching applications. To cancel this dialog box, users must press ALT GR + DELETE. To prevent this problem, create separate sites for users logging on with smart cards and users logging on using explicit credentials.

ICA file saves to disk during client launch

In some cases, when the client is launched, the .ica file is saved as a plain text file on the user’s hard disk. However, this does not prevent the client from launching successfully. [#146110]

Error message when attempting to connect using clients prior to Version 6.20

When attempting to connect to a remote application with client versions earlier than 6.20, you may encounter the error "50: Cannot connect to server." The recommended solution is to upgrade to the latest versions of the clients. However, if this is not possible, the error can be prevented by editing the template .ica files as follows:

1. Using a text editor such as Notepad, open the following files: default.ica, bandwidth_high.ica, bandwidth_low.ica, bandwidth_medium.ica, and bandwidth_medium_high.ica. These files are typically located in the C:\Inetpub\wwwroot\Citrix\SiteName\conf\ directory on Windows and the WEB-INF directory of the Web Interface site on UNIX.
2. Locate and delete the following lines in each file:
   DoNotUseDefaultCSL=On
BrowserProtocol=HTTPonTCP
LocHttpBrowserAddress=!

Native client cannot be upgraded on devices running Windows XP Embedded

The Web Interface may offer to install or upgrade the native client on devices running Windows XP Embedded; however, the installation will fail. You can avoid this issue by manually installing the latest version of the native client on the embedded device. If this is not possible, you can use the Access Management Console to stop these installation captions from appearing:

1. On the Windows Start menu, click All Programs > Citrix > Management Consoles > Access Management Console.
2. Click Manage client deployment.
3. Click Client Detection.
4. Under Display client detection notification, select either Only if applications cannot be launched or Never.

Web Client support for Firefox 2.0 on Windows XP and Windows Vista

Under certain circumstances, not all the features of the Web Client are available using Firefox 2.0 on Windows XP and Windows Vista. If Firefox is installed by a user with administration privileges on a computer running Windows Vista with User Account Control switched off or Windows XP, installation of the Web Client by a user without administrative privileges will not include the ICO plug-in for Firefox. On Windows Vista with User Account Control switched on, the ICO plug-in for Firefox will not be installed unless the user is logged on under the built-in administrator account created by the operating system or the built-in administrator account for the domain to which the computer belongs.

When the ICO plug-in for Firefox is not installed, the client detection, workspace control, and embedded launch features are not available. To avoid this issue, both Firefox and the Web Client should be installed by a user with the appropriate administrative privileges (the built-in administrator account or built-in domain administrator account in the case of Windows Vista with User Account Control switched on). Users without the appropriate privileges should be instructed to ignore prompts to upgrade the native client. Alternatively, the installation captions that allow users to upgrade their clients can be disabled by following the procedure detailed in "Native client cannot be upgraded on devices running Windows XP Embedded" above.
