We have a problem with loading NAL on Windows 2003 SP1, Citrix Metaframe
4.0 server.
The server works fine, out of the blue the NAL takes about 5 to 10 minutes
to load the application launcher.
After the user is logged in (the login doesn't take longer, the
loginscript runs normal) the NAL icon is displayed as off-line, after 5 or
10 minutes the NAL refreshes and loads the NAL in the Startmenu.
During this the utilization, memory and the NIC of the server look fine.

Extra information:
We have Zenworks Desktop Management 6.5 SP1 on a Netware 6.5 SP2 server.
About 2000 users log in with a normal workstation (ZFD6.5SP1 Agent), they
have no problem.
About 200 users log in with a TC on the Terminal Server (ZFD7 Agent), they
have these problems.
Both the workstations and the Term server use NWClient 4.90SP2.

Does anyone know how to resolve this?
