https://*.ibm.com
https://www.ibm.com

For Internet Explorer 8, go to Tools > Internet Options > Security > Trusted Sites > Sites > Add

Problem:
When you try to start an application on the Citrix Server, the following error message is displayed: “Cannot connect to the Citrix XenApp server. The Citrix XenApp server you have selected is not accepting connections” or "No Citrix MetaFrame Server configured on the specified address."

Cause:
This error usually happens when your computer is protected by either a hardware or software firewall. That is, there is a firewall between your computer and the Citrix Server.

Solution:
The following ports must be open in the firewall to allow Citrix internet traffic to pass through to communicate with the Citrix Server:

• TCP/IP Port 1494 (INBOUND)
  Important note: In environments where Session Reliability is enabled, TCP/IP port 2598 replaces port 1494 as the port that the ICA protocol uses. See this blog post for more detail.
• TCP/IP Port 443 (INBOUND & OUTBOUND)
• UDP Port 1604 (INBOUND & OUTBOUND)

To reconfigure the Windows XP SP2 firewall to allow Citrix traffic to pass through:

1. Click Start, Run, and enter wscui.cpl.
2. Click the Windows Firewall icon.
3. The Windows Firewall window is displayed.
4. Make sure Don’t allow exceptions is deselected.
5. From the Exceptions tab, click Add Port.
6. The Add a Port dialog box is displayed. Enter any name in the Name field, enter 1494 in the Port field, and select TCP.
7. Repeat to add ports 443 (TCP) and 1604 (UDP).
8. Click Exit to exit Windows Firewall setup.
9. Log on to the Citrix Server again.

• Double-click the Citrix icon in the system tray (by default, the system tray is in the lower-right corner of the desktop).
• Click File security

Problem:
SSL tunneling is not enabled on the appropriate ports.

Cause:
This error appears to be related to opening ports 1494 or 2598.

Solution:
Consult the Citrix article Configuring Microsoft ISA Server to Allow Outbound ICA Connections..

Problem:
When accessing Citrix-delivered applications via the Citrix web Interface, you can log in and see the icons for applications. You have the Citrix client for PC installed, but when you try to start an application, the message “ICA file not found” is displayed and the application does not start.

Cause:
This problem occurs when the Temporary Internet Files cache folder used by Internet Explorer becomes too large, causing too much delay when saving the .ICA file that is used to launch an application from the web. The error is displayed because the browser can’t find the file.

Solution:
Clear the browser cache as follows:

1. Open Internet Explorer and navigate to Tools > Internet Options....
2. On the General tab, click Delete Files.... You may also want to click Settings... to decrease the amount of disk space to use for the Internet cache.
3. Restart the browser and you should be able to connect to Citrix applications.

If that fails:

1. Open Internet Explorer again, and navigate to Tools > Internet Options....
2. On the Advanced tab, scroll to the Security section, and ensure that the checkbox for Do Not Save Encrypted Pages to Disk is deselected.
3. Click OK and restart the browser.
