SUMMARY

This article describes how Microsoft Systems Management Server (SMS) creates the Cyclical Redundancy Checksum (CRC) entries for client programs.

SMS uses a file integrity method that prevents the start of a program by the Systems Management Client service if the program does not match the CRC generated for that program by the site server.

MORE INFORMATION

When you find that mismatched files exist between the client, the logon point (in SMS 2.0 only), the client access point (CAP), and the site server, it means that there has been a previous unsuccessful attempt using the verification process.

SMS maintains the list of client files that require CRC generation in the Sitectrl.ct0 site control file. The following example lists a typical entry:

BEGIN_CLIENT_CONFIGURATION
<Client Properties> <3>
TARGET_PLATFORM <ALL>
SITE_KEY_FLAGS <0>

The Client Install Data Manager uses the data from the preceding file to locate the client files, and then to generate the CRC data. The CRC is built against the files located in the site server's \Bin\i386 and \Bin\Alpha directory structure. It then populates the CRC data in the Cli_inst.cfg file located in the \SMS\Inboxes\Clidata.Src folder on the site server. The Inbox Manager copies this file to the Clidata.box folder on the client access points. The client, when installed, takes the reserved data from the Cli_inst.cfg file, and then inserts it into its local registry.

When the SMS Client service tool (Clisvcl.exe) starts, it attempts to start each individual client program. When it undertakes this process, it checks the CRC of the local file against the registry built from the Cli_inst.cfg file. If it does not match, you can receive the following error message:

#$#$#$#$#$ ERROR: The Client Service is not authorized to run this application (5)
