With the advent of Windows Server 2012 R2, Microsoft has worked diligently to provide support for virtualization and allow corporations to reduce costs by virtualizing as much hardware as possible. New features in 2012 R2 help prevent USN rollback and/or Lingering objects via the new VM-Generation ID. If a guest o/s is restored from a snapshot the VM-Generation Id that is stored in the DIT (msDS-GenerationID attribute on the DC’s computer object) is compared to the value on the Host. If […]
Ace here again. I thought to touch base on DNS zones, and more so, focus on what AD integrated zones are and how they work. This blog almost mimics my class lecture on this topic. Check back for updates periodically, which I will notate with a timestamp above with whatever I’ve added or modified. This topic was also briefly discussed in the following Microsoft Technet forum thread: Technet thread: “Secondary Zones?” http://social.technet.microsoft.com/Forums/en-US/winserverNIS/thread/c1b0f3ac-c8af-4f4e-a5bc-23d034c85400 source: http://blogs.msmvps.com/acefekay/2013/04/30/dns-zone-types-explained-and-their-significance-in-active-directory/
There are some specific concepts in active directory which may put your environment in trouble if you do not attend to fix them as soon as you notice. One of them is Lingering objects. Defining the meaning of Lingering Objects (LO) is not difficult. Basically if an object in your active directory partitions exist in one or more domain controllers and not exist in the rest of the domain controllers in the same partition. So you may ask yourself how […]
Group Policy can be difficult to design, implement, and troubleshoot unless you are fully aware of the foundational concepts that drive Group Policy with Active Directory. There are many moving parts with Group Policy, not to mention the reliance that Group Policy has on Active Directory functioning properly. When making changes within a Group Policy Object (GPO) in hopes for a desired outcome, only to have Group Policy not working correctly can be very frustrating. many article is founded in […]
last week , i try to work with Windows 2008 R2 server but my system restart frequently . after research i find Reboot problem.

I am sure you must have experienced VPN reconnect – a new IKEv2 based VPN tunnel that is added in Windows 7 that allows automatic and seamless switchover of an active VPN connection when the underlying Internet interface (connection) changes thus maintaining application persistence.
