Outlook 2007 Slowness on Windows 2008 x64
Filed Under XenApp | Leave a Comment
Recently whe working with a client, we ran into an issue with brutally slow Outlook 2007 performance when running Outlook on Windows 2008 x64 with XenApp 5. The issue occurred whether connecting through the console, RDP, or ICA. All other applications worked fine. Some of you XenApp gurus may have already seen this. When checking the Outlook connection status, we could see average response times of 3000 milliseconds. After some troubleshooting involving removing and reinstalling Outlook, going with a plain vanilla Outlook install with no updates etc. we were still not able to resolve this issue. We did some digging and found various references on google about Outlook being slow on recent OS builds. All indications pointed to a new TCP auto tuning feature. After running -
netsh interface tcp set global autotuning=disabled and rebooting the server Outlook responded great. Now, I haven’t research what the implications are of disabling tcp autotuning, but it certainly resolved our only issue and everything continues to perform well. Hope this helps someone else that runs into this issue!

XenDesktop and vCenter 4 Integration
Filed Under Citrix, Provisioning Server, Virtualization, XenDesktop, vCenter | Leave a Comment
I was performing a XenDesktop POC where the hypervisor was ESX 4 and vCenter 4. For those that do not know, XenDesktop is hypervisor agnostic and can be ran on ESX, Hyper-V, and XenServer.
During the XenDesktop Setup wizard, I could not get the XenDesktop Delivery Controller and Provisioning Server to communicate with vCenter.
I was getting the following –> Error : “The hosting infrastructure could not be reached at the specified address”
After digging, I found a handy post by Trond Eirik Haavarstein on this specific issue. Thanks Trond!!! This was very helpful.
Here is the link, and I have included the helpful article below:

I am working on a new Citrix XenDesktop Proof of Concept (POC) hosted on VMware ESX. During the setup I discovered some error messages I would like to share with you.
Error : “The hosting infrastructure could not be reached at the specified address”
Solution :
- Create a host file entry that resolves vmare to the IP address of your VirtualCenter Server. Do this on the Desktop Delivery Controller (DDC) and the Provisioning Services Server (PVS).
- Import the certificate from the Virtual Center Server (%systemdrive%\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\SSL\rui.crt) into the trusted root authority for Computer Account – Local Computer (used the Certificate MMC to accomplish this). Do this on the DDC and PVS.
Use https://vmware/sdk in the XenDesktop Setup Wizard.

Ubuntu 9.10 Karmic Koala w/ VMware Workstation and Windows 7
Filed Under Ubuntu, VMware Workstation | 5 Comments
So I was having issues with Windows Vista on my T61 build and decided it was time for a change.
I thought I’d have a little fun and put Ubuntu on my laptop. I’ve never ran a Linux OS as my primary OS.
I also loaded VMware Workstation 7 and a Windows 7 virtual machine.
So far, Ubuntu has been really easy to use. I’ve had very few snags so far. I was even able to get Office 2007 installed natively using CrossOver.
I tried WINE but could not get Office to load with that one.
Overall, It’s been very easy to use Ubuntu as a primary OS. I use the Unity feature in VMware Workstation when I need to access any Windows related apps.
So far, that has not been very common. Mostly, I need to use windows for the SSL VPN connections that I have to make.
The only major snag for me so far is that running music from my Windows 7 VM is choppy. If I run it directly on Ubuntu, the sound is great.
I use iTunes so running music from the VM is necessary. I have heard of people getting iTunes to work using WINE but it did not work for me. I’d rather run iTunes from the VM. Hopefully, someone knows of a tweak to get the sound from the Windows VM to work properly and not be choppy.

VMworld 2009 Keynote Day 2
Filed Under Uncategorized | Leave a Comment
Herrod is immediately covering the desktop space and VMware View.
Covering the PC Experience Over the Network (PCOIP). PCOIP will ship with a software only protocol but will have a hardware acceleration option. PCOIP will ship this year!
Herrod is touching on Hosted Virtualization for “Employee-Owned IT”. Basically, the concept of BYOC – Bring Your Own Computer.
Also discussing a Bare-Metal Virtualization for “Corporate-Owned IT”. I’m really digging the bare-metal virtualization that will be happening on laptops.
- No host lesss management and patching
- 3D graphics and local performance
Demo: On the Client Virtualization Platform
I’m very impressed with the full motion video and 3D Graphics from the user experience.
Now performing demo from a home PC to a View session demonstrating the user pc experience.
***Moving to demo on connecting to a View desktop from an iPhone using the WYSE pocket cloud. Very cool!!

I’ve had a very busy VMworld so far dedicating time to networking and sessions. This evening I also had a full schedule on happy hour and parties. I started of the evening at the Thirsty Bear where the south central teams for VMware, Cisco, Intel, and Iland hosted the event. Later, I attended the WYSE party at the OLD MINT where there was great food, wine, and live performance. Check out my video from the OLD MINT.
