How to Perform SYSVOL Migration from FRS to DFRS Replication

How to Perform SYSVOL Migration from FRS to DFRS Replication

Video Tutorials, Windows Server
Domain controllers use a special shared folder named SYSVOL to replicate logon scripts and Group Policy object files to other domain controllers. Windows 2000 Server and Windows Server 2003 use File Replication Service (FRS) to replicate SYSVOL, whereas Windows Server 2008 uses the newer DFS Replication service when in domains that use the Windows Server 2008 domain functional level, and FRS for domains that run older domain functional levels. To use DFS Replication to replicate the SYSVOL folder, you can use the procedure that is discussed in this video tutorial to migrate replication to DFS Replication. Pre-Requisites: Check Active Directory health using DCDiag and Repadmin and make sure there are not errors. Use net share from elevated command prompt on all DCs to check Netlogon and SYSVOL share status. Change…

How to Perform Authoritative DC Restore for Windows Server 2008

Video Tutorials, Windows Server
When a domain contains more than one domain controller, Active Directory replicates directory objects, such as users, groups, organizational units, and computers, to all the domain controllers in that domain. Authoritative restore is a method to recover objects and containers that have been deleted for AD DS. An authoritative restore marks specific data as current and prevents the replication from overwriting that data. The authoritative data is then replicated throughout the domain. The process for performing an authoritative restore of AD is the same as a Non-authoritative restore except for one step. After the restore of AD is complete in DSRM and then, before restarting, you manually run Ntdsutil, and the mark the object that you want to restore as Authoritative.

Windows Server 2008 R2 Best Practices in VMware vSphere 4.X

VMware, Windows Server
Be sure the virtual machine has at least 2GB of RAM. Hard drive for the virtual machine must be 20GB or larger. Single VCPU works better for Windows 2008, Because Windows 2008 uses high bit rate address space for context switching when compared with Windows 2003, which creates multiple cycles of high bit range contexts and these are better addressed by Single VCPU. (this again vary if it is a DB server). VCPU will get hit, when VMware have wide variety of hardware components attached to VM (Majorly Serial and Parallel COM ports, USB controllers, Sound Cards etc), if any of these components are not required, remove them and disable them from VM BIOS.

How to Perform Step by Step Exchange 2010 Single Mailbox Item Restore with Windows Server Backup

Exchange Server, Video Tutorials
Exchange Server 2010 no longer has the notion of Storage Groups, which were used in Exchange 2007 and 2003 to contain logical groupings of databases. Exchange 2010 now simply lets you create databases on mailbox servers. The difference is that in Exchange 2003/2007, you created a Recover Storage Group (RSG) to restore the database into. In Exchange 2010, you simply restore the database and connect to it as a Recovery Database (RDB). While the main purpose of Exchange backup is to enable server, storage, and datacenter disaster recovery scenarios, a common and routine request of Exchange admins is to restore an individual mailbox. Microsoft does not provide a native and fully automated way to granularly restore a single mailbox from an Exchange database backup. In this video I'll demonstrate the…
