How can I update an Unmanaged Client without Internet in an environment where there is a only 1 machine ( say X) that is connected to the internet and communicates with SEPM. The other clients are just standalone PC's which communicates with only X. So how can this unmanaged client communicate and collect information from it?

Please tell me the steps to do it. Its very Urgent

This CLIENT PC is a standalone machine.

1)not connected to the network but only communicates with X (parent PC).

2) no internet enabled

So how can we get the  virus updates/definitions updated on this CLIENt automatically

the quick and easy method is to download intelligent updater from the below link in the machine that has internet connect and update the other clients manually by copying it to a flash drive and executing them locally.

But GeoGeo, the issue will the Client get the GUP information? because it is not managed client and does not communicate with SEPM

you already posted this: https://www.symantec.com/connect/forums/unmanged-client-without-internet-needs-be-updated

an unmanaged client cannot talk to a GUP or SEPM. intelligent updater is what needs to be done

If X parent PC has access to the SEPM setup a policy to make X parent PC into a LUA and allow the stand alone machine to use X Parent PC for automatic def updates only.

You can only get the logs locally on an unmanagged client but the LUA at least will keep the defintions up to date and on the latest.
