Setting up Websense Express.

I would like to implement Websense Express in a 60-70 computer network for the co. I work for. I'd like to trial this software before I make final decisions. We have three seperated buildings. In two buildings, each have a DNS server. Both are running Windows 2003 R2. I believe they replicate with each other when changes are made with AD, Exchage server, etc.

We have an extra Dell server that we have not put into use yet, and I've been allowed to use it to test software and such. I want to setup Websense with this server. It originally had SQL Server 2005 all ready installed. I had to uninstall the '05 SQL Server in order to install the Websense Express software. I did a fresh install of Websense, and it also installed the MSDE that's required with Websense.

After installing Websense, I used the network monitoring tool to see what it detected. It has only been detecting 3-4 computers. It detects the same computers always. It's only detecting our domain servers (which is two), and I think it would also detect our Exchange server. I don't remember exactly as I was messing with it a week ago, and havn't touched it since. I enabled both NIC's, and I asked the other IT tech I work with if both NIC's are connected to the same switch as the domain servers, he said they were. They are supposadlly connected to the network with the rest of the 60-70 computers with nothing in between. Technically it should be detecting way more than just our domain, and Exchange servers.

Any ideas? All help, advice, and tips would greatly be appreciated.

Thanks

I'm not sure if you have done this or not, but I know there is some setup that needs to be done on your routers also that basically pushes the traffic to the websense server. I would love to help you out more, but I didn't actually do the programming on our router.

If that is all set up I would check your services to make sure they are all running. We have 11 different services running for Websense. The Websense Network Agent and Websense User Service are a couple of them you might want to check.

Something else you can check is in the Websense Manager, if you go to Server | Settings then Network Agent, make sure you have all your IP address ranges set up properly to include all your systems.

If none of these fix your problem, I have a few more suggestions, but don't have the time to type them out right now. I'll check back to this post later to see if any of my suggestions helped at all.

I've never messed with the routers/switches here. So I'm not farmililar with them at all. I'd have to leave that up to the other tech I work with. So that may not be configured right as you mentioned.

I didn't remember reading much about setting up the switches in the installation guide. So I looked back into the guide, and I read some of it again. It saids that both NIC's must be connected to the internet during the Websense installation. When I ran the installation, one of the NIC's was disabled through the device manager. I enabled the 2nd NIC after the installation, when I noticed it was disabled. Also, my co-worker had me take off the default gateway on the 2nd NIC that I had to enable. Do both the NIC's need to be setup with the same gateway?

I also read that the NIC can be connected to

a) "An unmanaged, unswitched hub located between an external router and the network."

or

b) "The span or mirror port on a switch or router, configured to use mirroring or bi-directional (2 way) port spanning."

mcclellanfsu, I'm guessing that the switches that were setup in your place supported port spanning or mirroring. I'm thinking that if I'd set it up with a unswitched hub, it would require us to disconnect cables and buy an extra unmanaged, unswitched hub for this. Oposed to just setting up our switched with the port spanning/mirroring. I guess I'd have to do first things first, find out if our switches support this port spanning.

We have one smart switch that we can hook up the Websense server too. We'd have to configure the switch for Websense to work properly. Websense has tech support that can help me setup the whole thing. But I have been looking into an appliance called iPrism, so I may not even use Websense anymore.

Thanks for the the effort mcclellanfsu.
