You should be aware of the following limitations before installing the ZENworks® Middle Tier Server:
ZENworks 7 Desktop Management does not support the installation of the ZENworks Middle Tier Server on Windows NT* 4 servers.
ZENworks 7 Desktop Management does not support the installation of the ZENworks Middle Tier Server on Windows Terminal Servers running in Application mode. For a Windows Terminal Server to function as a ZENworks Middle Tier Server, it must be run in Remote Admin mode.
ZENworks 7 Desktop Management does not support the installation of the ZENworks Middle Tier Server in a Novell Clustering Services™ environment. For more information, see Section B.0, Installing in a Novell Cluster Services Environment.
By default, the Apache Web Server is configured to communicate on ports 80 (HTTP) and 443 (HTTPS), but if other NetWare 6 components, such as Novell iFolder® and iPrint, were also initially installed on NetWare 6, it is possible that the NetWare Port Resolver has assigned ports 80 and 443 to an HTTP stack other than Apache.
Novell iFolder also uses Apache for its operations. If the Apache server in iFolder 1.3 is loaded into protected memory space, not kernel memory, it creates a different instance of the HTTP stack. The Desktop Management Agent communicates with the ZENworks Middle Tier Server using the ports configured for both Apache and the Desktop Management Agent. For more information about configuring ports, see Section 5.4, Configuring Ports for the Middle Tier Web Server and the Desktop Management Agent.
The ZENworks 7 Middle Tier Server does not support the multiprocessor-enabled version of the Apache Web Server on NetWare 6. Installing the ZENworks Middle Tier Server on a NetWare 6 server with the multiprocessor-enabled version of Apache abends the server.
There is no such limitation for installing the Middle Tier on NetWare 6.5 or later.
Novell NetStorage is not supported on ZENworks 7 Middle Tier Servers installed on NetWare 6. If you intend to use NetStorage beyond its Desktop Management functions, we recommend that you install NetStorage on a separate server.
Novell NetStorage is installed with the ZENworks 7 Middle Tier Server. If you intend to use the ZENworks Middle Tier frequently, and if you intend to use NetStorage beyond its Desktop Management functions, we recommend that you also install NetStorage on a separate server to avoid Middle Tier performance degradation.
ZENworks 7 Desktop Management with Support Pack 1 downgrades the Middle Tier RPMs on OES Linux servers. Because of this downgrade, NetStorage stops working. We therefore strongly recommend that you do not install ZENworks 7 Desktop Mangement with SP1 on the same server where Novell NetStorage is installed. For more information see Section 42.5, Interoperability with Novell NetStorage.
If you install the Novell Client™ on a Windows 2000/2003 server, then install the Middle Tier Server on the same machine, then uninstall the Novell Client from this server, the Middle Tier Server fails. The client uninstall program removes important files needed by the ZENworks Middle Tier Server.
In this same software combination scenario, if you subsequently upgrade the client to 4.9 SP2, a different version of nicm.sys is installed. If you do not use the nicm.sys included in ZENworks 7 Middle Tier Server, the Middle Tier Server fails.
To work around this issue, you have two options:
If you try to authenticate through the ZENworks Middle Tier Server to a Desktop Management Server installed on a Windows 2000/2003 machine that already has Active Directory (installed because the Desktop Management Server acts as the Primary Domain Controller) and eDirectory (installed to accommodate ZENworks Desktop Management) both installed, the authentication fails unless the user logs in with a full context.
The reason for this failure is a contention for the default LDAP port between the Active Directory and eDirectory LDAP listeners. To work around this port conflict, during the installation of eDirectory, choose an LDAP port other than the default, then use the NSAdmin utility in ZENworks Middle Tier Server to configure the ZENworks Middle Tier Server to communicate over that port.
To configure the LDAP port using NSAdmin:
In the Address box of Internet Explorer, type the URL for the NSADMIN utility. For example:
http://Middle_Tier_IP_address/oneNet/nsadmin
In the field of the LDAP Port configuration parameter, specify the LDAP Port number you already set in eDirectory and that the ZENworks Middle Tier Server should use to communicate with the Desktop Management Server, then click .
