Not seeing any errors in the log. What would an error look like though?
I used the intelligent updater and WAS able to get the new definitions with no issue. That's very useful but I don't think its feasible to go to 150+ machines and use it on each one
I ran the SymDiag (great tool, thanks for the heads up!) on one of the computers not updating and it didn't show any issues with the IPS definitions. Only issue was the "Host Integrity Definitions" don't seem to exist. I tried the fix button and it made it to the step where it re-downloads the definitions but it ran for about 50 minutes with seemingly no activity so I cancelled it. Not sure if that has any bearing on the issue or why those wouldn't be preset.
