As expected, I copied the GRC.dat file, and upon checking those logs I see the following:
rogress Update: TRYING_HOST: HostName: "liveupdate.symantecliveupdate.com" URL: "
http://liveupdate.symantecliveupdate.com" HostNumber: 0
HOSTS\0\ACCESS=liveupdate.symantecliveupdate.com
HOSTS\0\ACCESS2=http://liveupdate.symantecliveupdate.com
Do I have something misconfigured on my parent server somewhere? I have verified that the settings for the group are set to update from Parent Server.
