Somehow I missed the daylight savings change. It has really caused some issues in the past couple days. I believe we have finally updated everything.
Monday started with the phone system being off by an hour... calls before 11:00 were still going to voicemail. I finally found the fix for the Polycom phones here: http://kb.digium.com/entry/18/143/
The phone system and phones now have the correct time.
DNS and authentication went off line yesterday morning for about 20 minutes. It crashed hard again about 8:00 PM. I was outside cell coverage and didn't get it fixed until 10:30 PM. It appears to be a time related issue.
This morning I have updated the time zone files on every server in the house. I think everything should be using the correct time. This issue should be behind us.
