I faced this issue a few months back, where I could not patch one of our servers. Whenever I tried, I will got this : Error :  Windows Update Standalone Installer Installer encountered an error :  0x80070005 Access is denied.

Certificate Authority is a server role introduced by Microsoft, to issue digital certificates to target recipients. These digital certificates enable the environment to communicate securely between each other.  Installing an internal CA server is not too hard and pretty much straight forward I believe.  Description : Installing an Internal CA on Server 2012. How To Do :  Launch Server Manager , Go to Manage | Add Roles and Features  Click  Next >  Ensure Role-based or feature-based installation is chosen, and click  Next >      Ensure the target server is selected from the server pool, and click Next >   Check / tick Active Directory Certificate Services role  The Add Roles and Features Wizard appeared. Click at Add Features button.  Click Next >   Select additional features if needed, then click Next >

On one fine day when I was busy with one of my project, one of my collegue tapped my shoulder, a bit panicking. He : Heiry, take a look at this... Me : Dude, what on earth have you done? (serious face) He : I dont know man, I uninstalled .Net Fx 4.5, reboot the machine and this happened Me : Dude, What on earth was the reason you uninstalled .Net Fx 4.5? He : Well, I thought .... Me : (Evil Smile) So here is the thing. When we uninstalling .Net Fx 4.5, those related features would be uninstalled as well, including a feature called User Interfaces and Infrastructure. Please refer to  here . There are 2 ways to get it done - locally or remotely. For the purpose of this post, I will do it remotely from another Windows Server 2012 member server. Issues : Unable to view GUI in Server 2012. Troubleshooting : it is straight forward, GUI is disabled, RDP to the server, the only screen one can see is : Resolution :  RDP to another Serv

There are 2 types of Windows Activation - KMS and MAK. However, for this post, I won't be discussing on what are those or their differences, as this post is to discuss an error in regards to KMS implementation.  Issues : The following error has occurred. Please resolve the error and try again. Description : Access is denied Troubleshooting   Used multiple IDs (Domain Admins as well as Local Admins), however issue stll persist. Thus, it is safe to rule out User ID privilege from the root cause.  UAC is enabled. Resolution :  Go to Volume Activation Tools again, but right click at it and choose Run as Administrator ( not Pin to taskbar, sorry for that ) Browse to your server name ,and press Next. Punch in alternative credential if needed.  If you need to activate your KMS, get it activated. In this case, I already activated my KMS, so I will skip to Configuration.  Once all steps above compl

I think I rarely touch about Active Directory, so let's start with a basic one. Let say, one day you want to housekeep your OU structure, delete or maybe move some OUs to different locations, but you got an error : You do not have sufficient privilages to delete <OUName>, or this onject is protected from accidental deletion. or Windows cannot move object <OUName> because: Access is denied. Well, if we look at the first error, it is clear cut, the object is protected from accidental deletion, so the object needs to stay there. Whereas for second error, it just mentioned "access is denied".  Issues : Can't delete or move OU, either one of above errors prompted. Troubleshooting   Right click at the target OU, and click at Properties

I am using Windows Server 2012 for my XenDesktop 7 lab test. During the installation of SQL server, it prompted an error, asking for .Net 3.5 Framework to be turned on. I tried to enable it, but failed. Thinking and thinking, until I realized what was the issue Issues : Received below error while trying to enabling .Net 3.5 Framework feature in Windows Server 2012. Error : Installation of one or more roles. role services, or features failed. The source files could not be found. Try installing the roles, role services, or features again in a new Add Roles and Features Wizard session, and on the confirmation page of the wizard, click "Specify an alternate source path" to specify a valid location of the source files that are required for the installation. The location must be accessible by the computer account of the destination server. Troubleshooting  It turns out that to enable the feature, the source is needed. In this case, it will grab the source from int
