Sophos – Management server connection failed

Sophos, ,
Recently I came across the following error when going into a Sophos Enterprise Console (5.2.1) after an upgrade from 5.2.0 which struck me as a little odd. Management server connection failed Could not connect to the Management Server. This may be due to one of the following: • Local network problems • Management service has stopped on the server • Your database service has stopped. Either attempt to reconnect or close the application. Attempting to reconnect may take a few minutes. Clicking 'Reconnect' fails. (more…)

Re-Installing ADFS 2

Microsoft,
During your install and testing of ADFS, you may decide to re-install ADFS (in order to start with a clean sheet after initial tests and proof-of-concepts are completed). I uninstalled ADFS and run the setup again. I added Federation Server as the server role and configured all certificates – all going smooth so far. I jumped to creating a new Federation Service. When it comes to applying my settings it came up with a warning “Existing Web site detected”. Therefore, the Web site was not reinstalled. If you are trying to redeploy the default AD FS 2.0 Web sites, see…

Configuring Windows Time for Active Directory

Microsoft, ,
Over recent years I have noticed that Windows time configuration is sometimes overlooked and misconfigured and at some point may cause you major hassles. For anyone not aware, all machines in an Active Directory environment automatically find a time server to sync time with. Workstations use their authenticating Domain Controller, and the DCs sync with the server holding the PDC Emulator FSMO role. In a multi-domain forest, the PDC Emulator in each child domain synchronises with a DC or the PDC Emulator in the forest root domain. To ensure the time remains reliable across the forest, only the PDC Emulator in the forest…

Best practices for VMware Snapshots

VMware,
I have come across a number of forums and emails were people are unsure on the proper use of snapshots and on occasions using snapshots for the wrong reason.  I found a great VMware article which I think covers everything you need to know about snapshots and the correct use:- Snapshots are not backups. A snapshot file is only a change log of the original virtual disk. Therefore, do not rely on it as a direct backup process. The virtual machine is running on the most current snapshot, not the original vmdk disk files. Snapshots are not complete copies of the original…

Transfer/Seize FSMO Roles to Windows Server 2012 Using Powershell

Microsoft,
Following information explains the Active Directory FSMO roles transfer process using powershell cmdlets. If FSMO role holder DC goes under upgradation process or down, we think about FSMO roles as its important and we know the traditional NTDSUTIL way of transferring and seizing FSMO roles which takes few minutes. However, using the power shell this is relatively easy and completes within few seconds. Powershell command :  Move-ADDirectoryServerOperationMasterRole Transfering all 5 FSMO roles syntax: Move-ADDirectoryServerOperationMasterRole -Identity “Target_DC_name” –OperationMasterRole PDCEmulator,RIDMaster,InfrastructureMaster,SchemaMaster,DomainNamingMaster If target DC name is ADC, use below command to transfer all FSMO roles: Move-ADDirectoryServerOperationMasterRole -Identity “ADC” –OperationMasterRole PDCEmulator,RIDMaster,InfrastructureMaster,SchemaMaster,DomainNamingMaster Role numbers can be used in command instead of role names. Transfer all 5 FSMO roles using numbers: Move-ADDirectoryServerOperationMasterRole -Identity…

vSphere 5.1 GPU acceleration now supported on XenDesktop with HDX 3D Pro and XenApp with HDX 3D

VMware, , ,
VMware recently introduced GPU hardware acceleration support for its latest hypervisor release, vSphere 5.1. XenDesktop 5.6 FP1 and XenApp 6.5 FP1 have tested successfully with the new GPU acceleration capabilities on vSphere 5.1 and Citrix officially supports these configurations. vSphere 5.1 introduced two GPU acceleration methods: Direct graphics acceleration (vDGA) and Shared graphics acceleration (vSGA). vDGA is similar to XenServer’s GPU pass-through method where each graphics processor supports a single VM to enable high performance rendering for designers and engineers that require a dedicated GPU or for GPU sharing with multi-user XenApp VMs. vSGA is a light-weight implementation of GPU sharing designed for business graphics such as Microsoft Office…
