This document explains about the domains which are required for agent communication.
Communication across remote offices is possible in two ways:
Roaming Users directly contact the Patch Cloud Server. Since these users are constantly roaming, they can't be managed by a central server.
The Roaming Agents should connect to these four websites viz.
patch.manageengine.com - This is the Server's URL. The Roaming Agent updates the patch status to the Patch Cloud Server. In order to contact the Patch Cloud Server, the Roaming Agent has to connect to patch.manageengine.com.
patchdb.manageengine.com - This website will have the latest patch information along with the download URLs. To find the missing patches during the scan process, the agent gets the latest patch details from the patch database, for which it has to connect to patchdb.manageengine.com.
patchdatabase.manageengine.com - The Roaming agent has to connect to patchdatabase.manageengine.com in order to download dependency patches from the PMP Server.
dms.zoho.com - The Roaming Agent has to connect to dms.zoho.com, to perform on-demand operations. Say a user has added a new computer to the network, and he immediately wants to scan that computer. In that case, the user should perform an on-demand operation. So, the agent should connect to dms.zoho.com. By doing so, the user will be able to scan his systems immediately.
Distribution Server is a component which allows you to download patch binaries from the respective vendor websites and distributes it to all the computers managed by it.
The DS should connect to these websites viz.
The Agents which belong to remote office/WAN should connect to these two websites viz.
