My suggestion would be to locate the RSD sensor policies in the ePO dashboard and change the settings for Detect system OS details. This feature does the OS fingerprinting which can cause problems on some machines and print servers.
In the dashboard go to Systems icon at the top. Next in the horizontal menu bar choose Policy Catalog, Now use the drop down menu to select the Rouge System Detection policy. You can edit the default unless you have already created a custom one. Click on Edit. Now choose the fourth tab over label Detection. This screen you would want to look for Device details detection: Uncheck Scan detected system for OS details.
The OS finger printing option scans all the ports in hopes of determining the operating system. This is normal behavior if this feature is enabled. In answer to your question about what ports are scanned here is a list.

I hope this helps.
That is correct the ports listed are the list of ports the RSD sensor scans when the "Detect system OS details" is selected. This is essentially doing an OS fingerprint whereby it determines the OS based on the response it gets from those ports. You cannot disable any of the ports because doing so would make the fingerprint invalid so its all or nothing.
In ePO 4.0 if this causes a problem your only real solution is to either disable the aforementioned option or set the RSD sensor to ignore whatever subnet the problematic servers reside on.
In ePO 4.5 you can specify a list of MAC addresses on the Menu | Configuration | Server Settings | RSD Sensor page that the RSD sensor should never scan.
Hello William, Jeremy,
To test your suggestion, I need to installa RDS sensor on my computer for example; but when I tried to deploy RDS sensor 4.5 from my ePO 4.5 server, I got error about SNOWCAP_2000 installation on my computer . I have mcafee agent version 18.104.22.1681 installed on my computer.
Can I install RDS sensor 4.5 with my mcafee agent 22.214.171.1241 ? If it is not possible, how can I install manually RDS sensor on my computer (windows XP SP2 ) to do the test ?
Thanks for your help
The RSD 4.5 sensor is compatible with MA 126.96.36.1991; however, I would recommend upgrading to MA 188.8.131.524 at a minimum (that's MA 4.0 patch 3).
You can manually install the sensor by grabbing a copy of the sensor install package from your ePO master repository. By default that is here:
<ePO install directory\DB\Software\Current\SNOWCAP_2000\Install\0409\
Copy the entire 0409 folder to the client and you should be able to install the sensor by launching setup.exe.
You may want to review the sensor install log. Its called RSDSEN450-Install-MSI.logand by default it should be located in %windir%\temp\McAfeeLogs.
I have installed manually RSD sensor 4.5 on my computer has indicated by Jeremy (thanks).
You can find atttached the configuration of my RDS sensor on my ePO server.
I don't understand why my RDS sensor does not communicate with my ePO server on port 8444. Could you help me ?

Last information in my RSDSensor_out.log file was from 12/01/2010 when I tried to install RSD sensor from ePO server. It failed and I installed RSD sensor manually on my computer.
I have not any information about what my sensor is doing now and why it does not connect to my ePO server. I have a process call RSSensor.exe.
Is my configuration (sent in my last message) correct ?
If you have an RSensor.exe process running then you should have a RSDSensor_out.log. Without this log we have no way of knowing why the sensor is not communicating. I using ePO 4.5 with RSD 4.5 this log should be located here by default:
C:\Program Files\McAfee\RSD Sensor\RSDSensor_out.log
I can give you some generic suggestions:
- Make sure tomcat5.exe is listening on port 8444 on your ePO server
- Make sure you can telnet into port 8444 from the client: telnet <IP address of ePO server> 8444
