Below are details of why each of the listed Windows Computer Services are required by Rapid Recovery and AppAssure.
Provides three management services: Catalog Database Service, which confirms the signatures of Windows files and allows new programs to be installed; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from this computer; and Automatic Root Certificate Update Service, which retrieves root certificates from Windows Update and enable scenarios such as SSL. If this service is stopped, these management services will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.
Required for creating the listener service for API communication over HTTPS.
Internet Protocol security (IPsec) supports network-level peer authentication, data origin authentication, data integrity, data confidentiality (encryption), and replay protection. This service enforces IPsec policies created through the IP Security Policies snap-in or the command-line tool "netsh ipsec". If you stop this service, you may experience network connectivity issues if your policy requires that connections use IPsec. Also, remote management of Windows Firewall is not available when this service is stopped.
Required to establish connection security and network authentication.
Manages objects in the Network and Dial-Up Connections folder, in which you can view both local area network and remote connections.
Required for networking.
Required for allowing the Agent and Core to log to the Windows Event Log.
Registers and updates IP addresses and DNS records for this computer. If this service is stopped, this computer will not receive dynamic IP addresses and DNS updates. If this service is disabled, any services – e.g.: WinHTTP, that explicitly depend on it will fail to start.
Required for WinHTTP Web Proxy Auto-Discovery Service. It does not create IPs on the network, only allows for them to be requested from DHCP by the system on which this service is running.
