I faced a problem in Linux to type Persian. I installed the Persian language in setting and after changing my keyboard, I couldn’t type Farsi. After investigating many websites, I noticed that this was a horrible bug. To solve this issue, you need to run a command runner (alt+f2) and type “r“. Then, you could choose Persian language and type Farsi in your Ubuntu. I had this horrible bug (before downgrading to 3.32) where I would start an app normally […]

Docker is an open platform management tool for Linux Containers. It provides a means for developers and system administrators to build and package applications into lightweight containers. Docker consists of the following components: Docker Engine – A portable, lightweight runtime and packaging tool Docker Hub – A cloud service for sharing applications and automating workflows Docker is used to create image-based application containers. Image-based containers package an application with the individual runtime stack into a single container. This makes the container-independent from […]
Microsoft announced during this week’s Build Conference that its Azure Kubernetes Service (AKS), formerly known as “managed Kubernetes on Azure,” will reach general availability status “in the next few weeks.” The official name change to AKS was noted by Gabe Monroy, program manager lead on containers for Microsoft Azure. He also was the former CTO of Deis, a maker of open source tools for Kubernetes, a company that Microsoft acquired last year. The name change is worth noting because Microsoft has an Azure […]
One of the most interesting terms in virtualization that is appeared recently is containers. The containers offering a new layer of virtualization that are fit for packaging application. This type of virtualization allows to quickly build and deploy a large number of hosts or containers in a very short time and saves lots of time and money as compared to installing and deploying physical servers. Virtual machine ( VM ) have been around for a few years from now while […]
From 2 years ago, I decided to take part in VMware certification. last year, I have achieved the first certificate. Subsequently, I have got familiar with the next stage to complete your understanding and knowledge on VMware technologies and therefore, starting to study for VCAP-DCV exam. I’m of the opinion that, it is more difficult than all VMware certification in VCP level. I have read many articles and blogs about VCAP and it has always been a very elusive goal. […]

I find myself quite often trying to keep straight all the different replication activities that can occur within an Active Directory (AD) domain. There is: Intrasite Replication Urgent Replication Intersite Replication Intersite Change Notification Replication Reciprocal Replication Immediate Replication Manual Replication
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. If these servers are using File Share or SMB v.2, srv2.sys may cause this problem. Srv2.sys driver is root cause of this problem. This is SMB 2.0 server driver. You can download hotfix KB2552033 for Windows Server 2008 R2 SP1 with your own risk until Microsoft officially release it.

I encourage each of you to head over here to cast your votes again this year or for your first time. Voting is only open […]
Now that both Microsoft and VMware have officially announced the new released of their virtualization products it’s possible make an homogenous comparison between Hyper-V 2012 R2 (the fourth generation of Hyper-V) and vSphere 5.5. VMware vSphere 5.5 introduces several news and scalability improvements, on the other side Microsoft Hyper-V 2012 R2 consolidate its features and improve what was already existing in the 2012 version, with a limited (but significant) new features. For example now, finally, some VMware old date features […]
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. Isn’t that COOL – like VPN user moving from Wifi to WWAN and back – giving a true mobile connectivity to corpnet ! Yes it is… This means, Windows7 in-built VPN client and Windows 2008 R2 […]
About each folder under the SYSVOL share in Domain Controller SYSVOL folder used to store a copy of the domain’s public files like system policies, Group Policy settings and logon/logoff scripts, which are replicated to all other domain controllers in the Active Directory domain through File Replication Services (FRS), You can find many folders inside the SYSVOL share, I would like to explore and explain each folder by how it’s used in the process of SYSVOL replication.
trusting domain and the trusted domain For the diagram above, we have the following summary: When you create a trust from the Account Domain (trusted), the type of trust will be “incoming trust”. When you create a trust from the Resource Domain (Trusting), the type of trust will be “outgoing trust”. Remember that Direction of Trust is the opposite to Direction of Access.
