Hi,

I need to install SEP with a big number using a (Batch) and it would be great if it can set to exact time.

Thanks

It's possible with scripting. Create the package and put it on a share (DFSR) and have the script pull the install down to the clients. I haven't seen any good scripts on here to do it though.

I'd personally recommend taking a look at the SEP Integration Component for scheduled deployment of SEP en-masse using Altiris:

#EDIT#

Best part is that in being licensed for SEP, you automatically have the right to use this tool.  No additional license cost is involved

I have the idea but as you mentioned not yet any good script which i am looking for, i have a script which some times fail and some times success.

If you're stuck on the scripting side of things, have you considered writing a GPO batch to copy down the installer, and create a scheduled task to perform the actual install?

quick example:

xcopy \\networklocation\setup.exe %TEMP%

schtasks /create /tn InstallSEP /tr %temp%\setup.exe /sc once /st 20:00:00 /sd 05/31/2014 /ru "System"

As I mentioned though, I'd still recommend going with the SEP Integration component if I were you.
