Hi,

I'd like to write anything useful for you in this post but I could forget something, for this reason I suggest you to read the CD1\documentation\installation_guide.pdf file, section 1.

Regards,

First of all You have to install sepm server. for that I would suggest you to use windows 2k3sp2 server rather than using windowsxp on the server.

for clients  check whether any onther antivirus is installed or not if yes then uninstall it.then update the windows on client.

then you can deploy sep on client.

A Thumbs up for both Vkram and Giuseppe. I'd recommend that you follow what they've said, and also in addition to this make sure that all your systems are patched with the latest OS patches before you start the Migration / Installation process.

This may seem a bit odd, but it helps to be safe from known worms / threats going around on the net and the small window during the SEP installation process during which the system is exposed to possible exploit from threat(s).

I agree to Abhishek before blaming the Antivirus make sure you are all patched up with all security patches before and after deploying SEP. 

You could use the SEP_Support Tool and check for System Requirements to check if possible to install SEP.

In our company, we did a test environment and a test pc for every department. to check if it will run smoothly.

I would say familiarize yourself with these forums and some of the common issues regarding the Home, Reporting and Monitors tabs. Most are easily recognizable if not avoidable if you prepare. 

I also suggest to create a test environment first for SEP and clients.

wow thanks to all of you guys! :)
