SYMPTOMS
When an Independent Computing Architecture (ICA) client logs off a terminal server, ends the session, and then tries to reconnect, they receive the following error message:

Network or dialup problems are preventing communications with the Citrix server

The following event ID message is logged in the terminal server Application event log:

Event Type: Warning

Event Source: TermService Event

Event ID: 1004

Description:

The terminal server cannot issue a client license.



CAUSE
This problem occurs if all the following conditions are true:
 * The client is an ICA client.
 * The client uses Windows 2000 Terminal Services.
 * The client is on a network that has Citrix MetaFrame 1.8 for Windows 2000 Service Pack 2 or earlier installed.
 * The client connects to a terminal server, logs off, ends the session, and then tries to reconnect to the terminal server.

Note that ICA clients can connect to the terminal server the first time. This behavior occurs only when the client tries to reconnect.

This behavior does not occur with Microsoft Remote Desktop Protocol (RDP) clients.

This is a known problem with Citrix Metaframe 1.8 Service Pack 1 for Windows 2000.



RESOLUTION
To resolve this problem, obtain the latest service pack for MetaFrame 1.8 for Windows 2000. For more information about how to do this, visit the following Citrix Web site:
