But where time is jumping all over the place. That's a new one. after I re synced, It slipped an hour ahead. Check (as in look at) the timezone and the automatic daylight saving check box Says eastern time . wont let me change to Central Standard either What do you mean it won't let you? Is it grayed out? Is there a link to click in the window to enable changes to be made? When I change it to CST it says " Your current time zone is not recognized, Please select a valid time zone. " Try PowerShell: Set-TimeZone -Name "Central Standard Time" Or whatever zone you're in and is current. Powershell blows up Don't know what that means. Screenshot? even with copy paste it does that and elevated What's the result of this: $PSVersionTable Oh. That's why. Are you able to install PS v 5.1? I don't know the CMD.exe way to do it. Im not sure, Give me a few I'm sure a reboot would be required somewhere... but if you can, I found this: https://social.technet.microsoft.com/Forums/ie/en-US/3b13b6a0-ecb2-429d-ad8d-533b7322c7ee/installation-of-powershell-50-on-windows-2012-r2 I did not do this, I did however set it up to not be accessible from anyone but our Account which is completely locked and no one has the password, to see if the issue goes away.
