I echo the replies within and will add. New MacBook Pro and loaded up VPN and MS Office. Used SMP volume and a clean download as I have duplicated the scenarios multiple times following fresh installs in 3 machines now (described below).
Turn on VPN and try to access internal folders, results in Finder crashes, Dock Bar freezes and weird functionality. Also piles up other programs and by validation, does not seem to have any tie to MS Office (simply because I can duplicate this after a fresh install at the Genius Bar using their install & before MS Office is installed).
Once I was certain of a possible issue and after blowing the system out and reinstalling fresh 2 times (MBP 1 week old at that point), the continued crashes and Kernal Panics continued. Initially it seemed like a Flash or Ram hardware issue. After 4 days in and lengthy calls with 3 different Sr Advisors on Apple Tech Support, they were bamboozled and 2 of the 3 were confident it was a software related issue.
My frustration and incredible loss of work productivity drove me into the Genius Bar on Jan 4, 2018. After 3 hours of testing, all hardware showing OK, I was able to show them the weird hang-ups I was having. They re-installed their software. During this, I loaded my settings and VPN login into their MBP and was unable to duplicate problem. I tested my hotspot instead of their store WIFI, still fine.
Once I loaded up their new load of 10.13.2, I setup and turned on VPN. I was able to KP the machine immediately,
Leader at the store was involved in this last re-pave of the IOS. They both agreed that it was a Ram issue which resulted in a new MBP.
The new machine was not in stock so received a day later. Setup as normal, turned off encryption and loaded VPN. Did not load any other software. I was able to make it KP as soon as I clicked through 4 folders on my server. Brand new machine out of box ~12 minutes.
Need help ASAP. Digging in all areas I can as this MBP was the 2nd in our company. The secret plan is to convert our company but this situation, it won't be long before I asked to go back to Surface. And that is death as you know...
