Introduction
This document describes important notes, limitations, open caveats, resolved caveats, and closed caveats for Cisco Secure Services Client (CSSC) Release 4.2.1.
System Requirements
Supported OS Environments
XP Professional (SP1, SP2), 2K (SP4), Win2K Servers (SP4), Win2003 Server
Novell Client version 4.91 SP1 with Hotfix TID2972711
New and Changed Information
New Features
This is a maintenance release and does not contain any new features.
Limitations and Restrictions
Unsupported Environmental Features
The following environmental features are not supported in release 4.0.5 or 4.1.0:
•
For example, CSSC does not function properly with IBM ThinkVantage Fingerprint device software versions earlier than version 5. It is recommended that users update to the most recent version available (5.6 at the time of this note) before evaluating compatibility with their individual machine. This update can be obtained at the following URL:

Important Notes
Roaming and Disk Protection Applications
Software that is designed to protect a laptop's disk drive from physical jarring prevents any disk drive access while vibration is sensed. When using this feature, moving a laptop from one access point to another can cause roaming delays (interruptions in network connectivity). Such delays should not significantly affect applications that are designed to withstand network interruptions. Users can, at some risk, disable the disk-protection utility. Many laptop manufacturers suggest that users stabilize computers by placing them in standby mode before they are in transit which should prevent any problems. CSSC has been tested with one such application, the ThinkVantage Active Protection System, to confirm this.
Disabling Multiple Clients
Do not configure multiple client applications (such as Windows Zero Config (WCZ) and Cisco Aironet Desktop Utility) in addition to CSSC to control an access point with the same SSID. Allowing multiple applications to carry out write operations (as well as carry on EAPOL messaging required for making a connection) through the same network adapter might disrupt both applications, resulting in unpredictable behavior in both client applications.
If you must configure multiple applications with the same network, you must disable all but one of the client applications and use the enabled client to make connections.
Note
CSSC can be disabled easily from the Client main menu or from the system icon. Individual adapters can be disabled easily from the Manage Adapter dialog. Disabling other third-party clients might not be a simple operation. If a third-party client cannot be disabled, it should be uninstalled. For example, the Cisco Aironet Desktop Utility (ADU) must be uninstalled to allow CSSC to control the wireless adapter.
User Certificates from the Windows Certificate Store
If you use user client certificates from the Windows certificate store, ensure that you understand the requirements for certificate storage and accessibility by machine and user profiles. For example, the use of client certificates from the Windows store is not supported when configuring a user-only network that requires pre-logon authentication. For more information, use the CSSC's help or user guide.
Restarting the CSSC Service
If CSSC becomes suspended inadvertently, the CSSC service must be restarted. If the service fails to stop or restart properly, you must restart the machine.
The service can always be restarted by restarting the machine.
If you have Windows administrative privileges, you can manually stop and start the CSSC service by choosing Start > Control Panel > Administrative Tools > Services > Cisco Secure Services Client.
Managing Adapters
If you get a message that a Serious Adapter Problem has been encountered and CSSC automatically releases control of the adapter, Cisco recommends that you reactivate control of the adapter through the CSSC's Manage Adapters menu item. If this fails, you must stop and restart the Cisco Secure Services Client Service through the Windows Services dialog or restart the machine.
Caveats
Open Caveats
These caveats are open for CSSC Release 4.2.1:
•
The Management utility runs on an XP operating system.
Workaround: If it is necessary to run on a Windows 2000 operating system, the file msvcp80.dll should be copied from the ...\CSSC Management Utilities\Microsoft.VC80.CRT directory to the
...\CSSC Management Utilities directory (up one level).•
Workaround: None available in CSSC. A possible work around is to change the ACS configuration to allow authenticated in-band provisioning.
•
•
•
Workaround: None.
•
Workaround: Configure CSSC to Prompt for Credentials and Remember Forever. This provides the ability to see the password retries and correct the password after the first attempt. The retries are timed, so if the user does not supply a new password within 15 seconds the authentication fails.
•
Workaround: None.
Adapter Problems
•
A lockup condition has been observed that causes the current network access device to cycle between failed (red) and connecting (yellow) as observed in the Manage Networks window. Network connectivity is lost and the system tray icon is either steady-state idle (grey) or connecting (yellow).
Workaround: Disable and then re-enabled the network adapter (Using either the client or adapter controls of the CSSC is not sufficient). From the Windows Network Connections window, select the Wireless Network Connection and right-click. Then click Disable in the resulting pop-up menu. Repeat and click Enable.
Resolved Caveats
These caveats are resolved for CSSC Release 4.2.1:
•
Manually disabling the CSSC Service (either by an administrator or a user) will cause a 10-minute delay on logon.

Cisco Secure Services Client for Windows 2K/XP User Guide Release 4.2
http://www.cisco.com/en/US/products/ps7034/products_user_guide_list.html
The user guide contains detailed information on operating, and locally configuring the client. The single guide covers the three distinct versions of the client: the out-of-the-box version, the deployed Configurable End-User's version and the deployed Preset End-User's version. The content is taken directly from the client's embedded help system documentation.
Cisco Secure Services Client Administrator Guide Release 4.2
http://www.cisco.com/en/US/products/ps7034/prod_maintenance_guides_list.html
The administrator guide contains detailed information on deploying preconfigured end-user SSCs. This document describes the components of the underlying XML schema which controls the content and format of the deployment distribution package (configuration file). It also describes several Administrator utilities that are available to assist in the deployment process.
