Multiple Websense endpoints
*
Third-party agents
Some Websense endpoint clients can run together on the same machine. For example, Data Endpoint can be installed with Web Endpoint or Remote Filtering Client.
Endpoint software can also be installed with third-party agents, such as an antivirus agent.
There are limitations in all multi-agent deployments to be aware of.
Multiple Websense endpoints
With the Websense Endpoint Package Builder, you can create packages for multiple agents (Web and data) and, depending on the agent, multiple operating systems (Windows and Linux). You can deploy these packages to the same or different endpoint (client) machines.
For example, you can deploy either Web Endpoint and Data Endpoint or Remote Filtering Client and Data Endpoint on the same machine.
You cannot deploy Web Endpoint and Remote Filtering Client on the same machine. The package builder does not let you create a single package containing both. Likewise, you cannot deploy multiple agents on Linux machines. Only Data Endpoint supports Linux.
Here are some other restrictions to consider:
*
If you are deploying Web and data endpoints on the same machine, you must deploy them at the same time.
*
The packages created by the Websense Endpoint Package Builder are backwards compatible with previous endpoint versions.
Third-party agents
By default, Windows XP and Windows Server 2003 limit the number of concurrent agents in a system. As a result, a fatal (BSOD) error may occur when users try to access files via DFS (Distributed File System) and Websense endpoint software is installed with more than 2 other agents.
To overcome this limitation, update client operating systems to Windows XP SP3 or Windows Server 2003 SP2 and follow the procedures below.
