network connection dropouts on domain
A number of computers in our office network are having network critical programs dropout once or twice a day.
At first I thought it was an issue with one of our switches because it seemed to be only happening in certain departments, but what I've found is that it is the specific program that is dropping out, and not EVERYTHING.
i've been looking through the event viewer on the client PC's and on the domain server and the only similarities of events that I can find around the general time of the dropout is that LiveUpdate (for symantec endpoint and/or backup exec) started, stopped and deployed.
I've checked the liveupdate policies but it doesn't seem to be paying attention to the schedule I made.
but then again, how can I even be sure it is liveupdate causing the network interruption?

You need to disable the update from the affected workstations.

I don't think it is the client PC's now as the issue is affecting computers that don't have SEP installed.
Our domain server (which is the SEP manager) also has SEP client installed. Maybe that is the issue.
Anyways, the problems that the server has is that it stops DNS temporarily (meaning none of the connected computers can browse the internet), interrupts QuickConference (a LAN instant messaging program) and interrupts client connections to a networked accounting program called Locus by LexisNexis.
It did it today at 12.25pm-ish which is about 1hr 15mins later than it usually does. I've had a look at event viewer logs and AGAIN, a LiveUpdate took place at around that time.
I've attached a copy of the event viewer system log, the SEPM system log (for the server) and the SEP system log (for the server's install) and a screenshot of the liveupdate policy settings/schedule.
I'm pretty confused with this.

how do I do this?
as far as I'm aware, there are no scheduled tasks set around the time(s) that liveupdate decides to do it's thing and it seems to at 11am-ish rather than the 1.05pm time I've set in the manager. Obviously I'm missing something.
