New WIndows Update Client Patch KB3050265 June 2015 Can save you from valuable memory issues on Client Computers & Servers

18 06 2015

This patch solves a very big issue where a scan for updates causes svchost.exe with wuauserv service take a lot of machine memory in the form of private working set,

Without this patch I observed on a windows 7 client the memory usage of svchost go from 250 (megs) to 1.3 (gigs) and when it’s done scanning the memory wasn’t freed in it’s entirety.

If you calculate the frequency of scans for updates and the amount of servers / workstation / VMs all together you will find that this patch can save a whole lot of precious resources.

Quicky: Chrome Enterprise and Flash on XenApp 6.5

10 03 2015

I had to install NPAPI (flash plugin for Mozilla) and disable the built in PPAPI used in chrome via the chrome launch command line parameters in the published application configuration.

*also disabled GPU acceleration as we saw chrome crashes with it under XenApp 6.5 sessions.





Monitor-Backlog and take actions with custom conditions

3 04 2014

Hi Again,
I needed a quick way to place a folder where files from clients in my environment are being constantly sent and imported elsewhere under closer watch for backlogging and performance troubleshooting, the responsiveness of a business process was reliant on how fast the files from the clients gets processed,
I wanted the following abilities:
– it had to be temporary as I just wanted to get a rough idea on the times of day I get bottlenecks if any
– I didn’t want to interrupt / burden the server with too frequent queries
– I wanted to do something that I can use later / recycle in some form for other uses
– I had to get an idea visually of how bad things are meaning i needed couple of condition (severities)

Check Services, Ping, Specific port for a group of servers, configurable by CSV, new version with menu

30 07 2013
Hi,
I updated the file and have added functionality:
– NEW: A menu pop and asks which farm to check (Sets of servers), automatically populates from farms in CSV, menu includes option to check all farms*, now it’s easier to keep one CSV file for all your farms / sets of servers.
*add a farm “All” and keep that line empty in csv.
– NEW: UNC check (with new CSV role “UNC”)
– NEW: DNS Check (very basic without overloading)
– NEW: Check services by name and IP
– NEW: The script has been made compatible to Powershell 2.0
– FIX: The script can be run from right click “run with powershell”




Check Services, Ping, Specific port for a group of servers, configurable by CSV and scalable and all with powershell

26 06 2013
Hi, there are some checks that are needed on a regular basis and doing them often requires me a tedious routine of remoting to each server just to view that a service is running, so I whipped up the following script to check the basic availability of a group of Servers, Where for each server the script can check services, telnet to specific ports and can be expanded to test additional items (by role for example),
I applied it to a XenApp environment and so I have the edgesight, Data Controllers, XML brokers, PVS provisioning servers, SQL, Web Interface, Appsense, NLB Virtual IPs etc., i didn’t need to test the actual XenApp worker servers, but i could just add lines to the CSV and have them tested.
And you could easily adjust it to a farm of web application servers just by editing the CSV file.
The script is configurable with a CSV file that holds parameters for the process.
Functions from: Jason Poyner
From his excellent script to check entire XenApp 6.5 architecture

RE : Software Assurance Pays Off Remote Connection to WinPE during MDT SCCM deployments

25 10 2012

I was trying to use “unattend.xml” to enable remote control using DART 7 Remote Connection tool during WinPE
as demonstrated here:

http://www.deploymentresearch.com/Blog/tabid/62/EntryId/36/Software-Assurance-Pays-Off-Remote-Connection-to-WinPE-during-MDT-SCCM-deployments.aspx

The “unattend.xml” is residing in the root of the boot.wim – X:\Unattend.xml
The first time the machine boots in to WinPE from PXE it uses this Unattend.xml and everything works great.

However, if a step to restart the computer to the boot image assigned for the task sequence which is the same boot.wim then after the restart the original “Unattend.xml” will not be used, instead a different xml called “winpeunattend.xml” which is located at “C:\_SMSTaskSequence\WinPE\WinPEUnattend.xml”
And that XML is being created “on the fly” or in runtime, when the TS is “Staging boot.wim”
and the SMSTS.log will log: “Creating WinPE Answer File” and “Successfully saved … C:\_SMSTaskSequence\WinPE\WinPEUnattend.xml”

The task sequence is from SCCM 2007 R3 with SP2 and the Advertisement is Mandatory and configured as “Access content directly from Distribution Point”.

I finally decided to go around the problem as even in Microsoft Communities I couldn’t get this answered answered

Properly Streaming a Java or JNLP Application (Java client settings in enterprise environment) – part 2

16 08 2012

In a previous post i mentioned JNLP Applets and Application streaming,

Before I dive in to the step by step part of making streamed applications work better when they involve web start applets (JNLP) I first want to provide you with better understanding on how JNLP works because I feel that what I did with Citrix application can be applied to other environments that don’t necessarily feature application streaming like enterprise centralized access for JNLP applications, I also provide some best practice for the beginners and to those looking to consolidate or move those applet to SBC environment or even to just manage them.

How to disable Kerberos to test NTLM

24 07 2012

So today I encountered an issue where i wanted to mimic the behavior of a server 2003 in an un-trusted forest to which i had no physical access to, The issue was that I was trying to take advantage of the NTLM Passthrough  authentication like described here:

http://support.microsoft.com/kb/102716

And it was successful for some of the authentication requests from a winPE 3 based task sequence, At some point during the task sequence I received what looked like an innocent error in from the task sequence, something about that the task sequence couldn’t find the WIM image during the “Apply OS Image” step, when i looked in the server 2003 BDP event viewer i saw an event for “Unknown User Name or Bad Password” and i know the password is correct because that same task sequence run daily in the organization i work in,

To cut a long story short (i’ll post that adventure on a later post) Read the rest of this entry »





How to Drain Users on Citrix XenApp on Windows Server 2003 or 2008..the easier way

Hi,

Just stumbled on a citrix KB suggesting a way to drain users’ sessions from a XenApp Server,

The article is found here: http://support.citrix.com/article/CTX119661

And offers creating a load evaluator with “Citrix User Load” rule and set it to 1,

Why not use the following Load Evaluator technique? Read the rest of this entry »
