SYMPTOMS
Consider the following scenario. You have either of the following products installed on a Microsoft Windows 2000 Service Pack 4 (SP4)-based server:
 * Citrix MetaFrame XP Server for Windows with Feature Release 3 (FR3)
 * Citrix MetaFrame Presentation Server 3.0

You install Update Rollup 1 for Windows 2000 SP4 on this Windows 2000 SP4-based server. After you install the update rollup, you use the Citrix Independent Computing Architecture (ICA) Client program on a client computer to establish a connection with the Windows 2000-based server. You then try to run a published program on this server.

In this scenario, when you establish the connection with the Windows 2000-based server, you notice that you cannot run the published program. Additionally, you are not prompted to enter the user logon credentials. Subsequently, the client computer becomes unresponsive and you have to end the ICA Client session.
