Can I Virtualize ALL My DC’s In the Domain?

omid.koushki

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 they don’t match then the Invocation-Id is updated with a new value and any RID’s from the machine are replaced with a new set from the RID Master.

So the question is, “Do I need a physical DC in my Domain?”  Continue reading “Can I Virtualize ALL My DC’s In the Domain?” →

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.

Top 10 Technology Trends for 2013

omid.koushki

What will drive the technology trends for 2013? Analyst firm, Gartner shares their prediction:

Mobile Device Battles
By 2013, mobile phones will overtake PCs as the most common Web access device worldwide and that by 2015 over 80 percent of the handsets sold in mature markets will be smartphones. However, only 20 percent of those handsets are likely to be Windows phones. By 2015 media tablet shipments will reach around 50 percent of laptop shipments and Windows 8 will likely be in third place behind Google’s Android and Apple iOS operating systems.

Windows 8 is Microsoft’s big bet and Windows 8 platform styles should be evaluated to get a better idea of how they might perform in real-world environments as well as how users will respond. Consumerization will mean enterprises won’t be able to force users to give up their iPads or prevent the use of Windows 8 to the extent consumers adopt consumer targeted Windows 8 devices.  Continue reading “Top 10 Technology Trends for 2013” →

Active Directory Maximum Limits

I ran across a document from Microsoft that lists maximum limits for Active Directory. This document pertains to Windows 2000 Server and Windows Server 2003. There is no reference to Windows Server 2008 in the document. However, the majority of the limits also apply to Windows Server 2008.

Below is a summary of the maximums. The full details, including rationale, can be found here: http://technet.microsoft.com/en-us/library/cc756101.aspx. Continue reading “Active Directory Maximum Limits” →
