Clients Receive "Error 1000 No Licenses Are Available" When Logging on to Terminal Server

ID: Q216843

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When ICA clients attempt to connect to a Terminal Server computer running MetaFrame, they may experience logon problems with regard to licensing. The clients may encounter the following message:

Error 1000 No Licenses Are Available.

The server in question will also log the following Event ID:

Event ID 1004
Source: TermService
Description:
Unable to acquire a license for user XXXXX, domain XXXXX.

These symptoms are usually experienced in conjuction with excessive logon and logoff attempts.

CAUSE

The errors are caused by a MetaFrame feature known as License Pooling. License Pooling allows MetaFrame servers to share installed licenses among each other. When a client connects, the license follows the client. In some cases, this license may not be returned to the server, thus causing the MetaFrame server to run out of ICA licenses. To keep the licenses on the server and disallow them from following the client, change the License Pool Count.

RESOLUTION

To change the Licsense Pool Count, perform the following the steps:

Open the MetaFrame Tools Group.

Select Citrix Licensing.

Select the installed license or licenses.

Click the License menu and then click Change Pool Count.

Change the number pooled to 0.
