Windows 8.1 Slow with USB 3.0 0

How To

Windows 8.1 Slow with USB 3.0

Finally, Windows 8.1 preview is released on last month and we can test it in our virtual platforms. I want to deploy Windows 8.1 for our Call Center users because Windows 8 has lower IOPS compare to Windows 7. Also it has very faster start-up compare to earlier versions. I had poor performance with USB controller on this version of Windows. xHCI controller (USB 3.0) is default controller for Windows 8. I found solution on VMware KB2057809 and if you are facing with same issue, You should remove current controller and replace it with  EHCI+UHCI controller.

View Agent 5.1: Best Solution to Install Silently

I had a big problem on last week for upgrade my clients View Agent from 5.0 to 5.1. We are using Windows XP 64-bit form 2 years ago for our Call Center’s clients and I have a plan for upgrade my View servers from 5.1 to 5.2, so I have to upgrade View agents t0 5.1 for compatibility with View 5.2 at least. As you may know, this OS is not supporting by View agent officially but View agent 4.6, 5.0 and 5.1 can working on that properly. I had upgrade from 4.6 to 5.0 before but I faced with some issues in test step and wrote a script for upgrade agents completely silent. First Step, Prepare Client for View Agent Installation First, I want to mention that if you have plan for deploy the agent by SCCM, you should forget that, because it’s impossible. Anyway, you have 3 issues that you should resolve them to do silent installation: First step, copy your installation data and scripts to a shared folder with everyone access. Second step, if you have very secure environment like me that administrative share is disabled on that by your security manager, you have to enable it via registry....

Introducing VMware NSX – The Platform for Network Virtualization

The VMware NSX platform delivers the entire networking and security model in software, decoupled from traditional networking hardware, representing a transformative leap forward in data center networking architecture. Overview:  Today’s data center is largely virtualized from a compute perspective, and has unleashed unprecedented benefits of agility, efficiency and capex/opex savings. What is less known is that virtual network access ports have exceeded physical network access ports in number, and this trend is accelerating. In fact, today, 40% of vAdmins manage virtual networks. Beyond virtual switching, the time is ripe to virtualize the rest of the networking stack, and accelerate our customer’s journey to the software-defined data center. At VMware, we’ve put together an all-star team, the Networking & Security Business Unit (NSBU), to address this opportunity, and bring virtualization-centric innovation to networking. This team has been responsible for many key foundational innovations toward network virtualization. We started with the best of Nicira, vSphere networking and vCloud networking and security technologies, and embarked on a mission to build a unified solution that will transform networking and security in the virtualized data center.  Today, VMware CEO Pat Gelsinger will be launching VMware NSX™, the platform for network virtualization, in his keynote at...

ESXi 5.0 / ESXi 5.1 Host Backup & Restore GUI Utility

Host configuration is important for an administrator. If you have a valid backup from your host’s configurations, you can restore that on your host or also new host in any case of issue. For example, when your upgrade process is failed or you have to replace your faulty server with new one. You can restore your backup on your server. It’s possible by use PowerCLI or vCLI but I found an utility made by Sean Duffy. What it is essentially, is a GUI that allows you to Backup ESXi 5.0 or ESXi 5.1 hosts to a destination of your choice on a local drive. You can download that from this link:http://www.shogan.co.uk/vmware/esxi-5-0-host-backup-restore-gui-utility-powercli-based/

Accessing Direct Console User Interface (DCUI) from an SSH session

I read a VMware article (2039638) about Accessing Direct Console User Interface (DCUI) today. I’m surprised about that becuase, I didn’t know any thing about accessing to that from SSH. I tested that and found it very useful, if you can’t access to your KVM, it can help you to access to DCUI and do your settings easily. Just you should run your SSH client and enter “dcui” on command line. Press CTRL+C to close that. You can use it on slow networks or from your home or in travel by using VPN.

Desktop Search – Event 3083 window search Mapi2Handler.1 cannot be loaded

Problem ========= Windows 2003/Event 3083 window search Mapi2Handler.1 cannot be loaded EventID:3083 Category: Gatherer Description:The protocol handler Search.Mapi2Handler.1 cannot be loaded. Error description: Class not registered Desktop Search Version 4 Analyze ======== The background on this issue is that there are two processes that can index on 64-bit machines. One process is 64-bit and can load 64-bit protocol handlers and the other is a 32-bit process, which can load 32-bit protocol handlers. In this case, since mapi (which is used to index outlook email) is 32-bit only when the 64-bit protocol handler process starts it tries to load the 64-bit version of the non-existent mapi protocol handler. It should call into the WOW64-32 layer to determine that this handler is correctly registered in the other CLSID hive and not display the error. For some reason this check is not passing most likely due to some incompatible vista only flag we are using when calling to WOW64.32 bit applications use [HKEY_CLASSES_ROOT\Wow6432Node\CLSID64 bit applications use [HKEY_CLASSES_ROOT\CLSID Solution Remove Windows Desktop Search or add the following registry entry ===== Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\CLSID{9E175BAF-F52A-11D8-B9A5-505054503030}] @=”Windows Search Service Office Outlook Protocol Handler” [HKEY_CLASSES_ROOT\CLSID{9E175BAF-F52A-11D8-B9A5-505054503030}\InprocServer32] @=hex(2):25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,00,74,00,25,\ 00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,73,00,\ 73,00,70,00,68,00,2e,00,64,00,6c,00,6c,00,00,00 “ThreadingModel”=”Both” [HKEY_CLASSES_ROOT\CLSID{9E175BAF-F52A-11D8-B9A5-505054503030}\ProgID] @=”Search.MAPI2Handler.1″ [HKEY_CLASSES_ROOT\CLSID{9E175BAF-F52A-11D8-B9A5-505054503030}\VersionIndependentProgID] @=”Search.MAPI2Handler” =====

If you want to reclaim disk space just run it without parameters and it will delete all profiles except your own and some special profiles needed by the operating system (like “Default”). Delprof2 has additional filtering options: you might want to delete locally cached copies of roaming profiles only or delete only those profiles that have not been used in a specified number of days. Delprof2 does it all, both on the local system and remotely. Special Features Exclusions and Inclusions with Wildcards It is a frequent requirement to delete all profiles except one or two which should be left unchanged.

Fix for Windows Search Service Startup Error 1053 in Windows 7

Recently I came across a problem in a Windows 7 PC where the Windows Search service failed to start, and manually starting the service using Services MMC resulted in Error 1053, with the following error message verbatim. Windows could not start the Windows Search service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion. And the following entry is recorded in the event viewer. Log Name: System Source: Service Control Manager Date: Event ID: 7009 Task Category: None Level: Error Keywords: Classic User: N/A Computer: Description: A timeout was reached (30000 milliseconds) while waiting for the Windows Search service to connect. Because the Windows Search service failed to start, the Indexing doesn’t run, and the controls in Indexing Options are dimmed out. Note that the Windows Search (WSearch) service is set to start automatically (delayed start) by default in Windows 7. Registry Fix To resolve the problem, download wsearch-1053-fix.zip, unzip and apply the wsearch-1053-fix.reg file (This fix is for Windows 7 PCs only.) After applying, open Services MMC (Services.msc), right-click Windows Search and click Start. Reference: http://www.winhelponline.com/blog/fix-windows-search-service-error-1053-windows-7/
