This is the another listen learn from my project in data center as well as reminder for myself.
After few months of installation and configuring all systems and servers, the times on Microsoft windows servers changed and there’s 1-hour missed.
All system configured to get their time config from NTP server in data center, all servers and NTP server are configured in GMT 3:30+ (Iran/Tehran).
For example in the time that NTP showed 6:30 PM, all windows server showed 5:30 PM, after searching for solution on internet, I come across KB979306 from Microsoft itself.
After downloading the KB and taking backup of one system with MS Windows 2008, I installed the update and just after all process of installation finished and before Finish button appear, the times sets to it’s correct state.
So if you finding such problem in your network, may be checking this update help you a little.
