Windows Time
Time sync issues between servers on a domain can cause many issues including login failures, connection problems, phone system crashes and other random issues.
Can use cmd commands to force time to sync:
w32tm /resync
or
NET TIME /DOMAIN
Change TimeZone
If the time zone is not able to be changed from the GUI open an admin powershell session and use the following cmdlet:
- set-timezone "GMT Standard Time"
