Disabling Day/time Savings #Microsoft #Windows #Egypt #DST

April 27, 2011 Leave a comment

The Egyptian government announced on Wednesday 20 April 2011 that summer daylight saving time (DST) will be canceled in Egypt. By default, all windows platforms configured with Egypt time zone (GMT+02:00) Cairo will start the DST by the last Thursday of April by adding one hour at 28 April 2011 @ 23:59:59.

Microsoft will be releasing a new hotfix to disable DST, however due to time limitation we might have a delay until we get that update, until further notice use the below steps to disable it.

As a workaround, to deactivate daylight saving settings and avoid adding an hour by the last Thursday of April, the “Automatically Adjust Clock for Daylight Saving” checkbox needs to be unchecked. Automated ways for Windows 2008 R2, Windows 7, Windows XP and Windows 2003 are listed below. Unfortunately, there is no automation in toggling this checkbox in Windows 2008 and Vista, it will need to be done manually.

Issue:

Windows Daylight Saving Time (DST) Will be canceled in Egypt 

Symptoms:

Your computer’s clock may start the daylight saving time (adding 1 hour) on the last Thursday of April at 23:59:59, and it may end the daylight saving time (deducting 1 hour) on the last Thursday of September at 11:59:59 PM.

However, in Egypt, daylight saving time has been canceled, and there is no need to add or deduct this 1 hour.  
The behavior will only occur if the Date/Time Properties settings are set to the following:

Time Zone is set to (GMT+02:00) Cairo.
-and-

The Automatically adjust clock for daylight saving changes check box is selected.

Business Impact:

· Active Directory Replication fails.

· Users will be unable to join / logon to all Active Directory Domains.

· The Global Catalog server is unavailable, and the Exchange services cannot be started.

· Users are not able to access their e-mail as the Exchange Server services are down.

· The Free/busy calendar information will show the old time (One extra hour).

· Calendar appointments will be off by 1 hour.

Resolution:

          Any of following resolution can be used:

· Microsoft Windows7 and Microsoft Windows server 2008 R2

“Automatically adjust clock for daylight saving changes” can be disabled by using a built-in command line utility called Tzutil.exe:

Tzutil.exe /s “Egypt Standard Time”_dstoff

The above command will clear the DST checkbox. You can run this command in a script file to force the change on all Win7/2k8 R2 machines. It’s recommended that you re-type this command rather than copy/paste from email.

· Microsoft Windows XP and Microsoft Windows Server 2003

“Automatically adjust clock for daylight saving changes” can be disabled by using the below commands with TZChange.exe:

reg.exe add HKLM\SYSTEM\CurrentControlSet\Control\TimeZoneInformation /f /v DisableAutoDaylightTimeSet /t REG_DWORD /d 1  

TZCHANGE.exe /C "Middle East Standard Time"  

TZCHANGE.exe /C "Egypt Standard Time"

The above command will clear the DST checkbox. You can run this command in a script file to force the change on all Win7/2k8 R2 machines. It’s recommended that you re-type this command rather than copy/paste from email.

· Microsoft Windows Server 2008 / Vista

“Automatically adjust clock for daylight saving changes” checkbox needs to be manually disabled.

#Lync Client #Virtualization the full story #ucoms #Citrix #xendesktop #xenapp

April 27, 2011 Leave a comment

if you have been reading carefully, Citrix released a document the article published here http://support.citrix.com/article/CTX128831 .

by that time, I knew internally that Microsoft didn’t support Client virtualization for OCS/Lync. although if you have been reading and even attended Citrix Xenapp 6 or Xendesktop training you will hear a lot about Lync/OCS client virtualization delivery with Xenapp or Xendesktop.

starting 14/4, Microsoft released a document that explains the supportability statement for Xenapp and Xendesktop and virtualization techniques that they support/no support.

the document is available here http://www.microsoft.com/downloads/en/details.aspx?FamilyID=f865e66d-1163-46ef-ba9c-d585376dfbae.

in summary Microsoft now supports client virtualization through full desktop or application delivery/streaming with some considerations “check the document for more details” it is so amazing to see that Microsoft finally released such a support statement and changed the fully rigid statement of the big NO before.

Automating #Linux Machines #provisioning on #Microsoft Hyper-v #Cloud using #opalis #hyperv

April 23, 2011 4 comments

I was assigned the task by one of my customers to automate their Linux machines provisioning on their Hyper-v cloud they are running, they still evaluating the Hyper-v Cloud capabilities, and they were wondering if they can automate the Linux machines provisioning into Hyper-v Servers.

They currently still evaluating it, so the process for the request and automation still not clear in their mind, but the question and request was simple, we want to automate the process of copying and configuring the machine, specially that they are running lots of Linux virtual machines.

the setup:

– 2 Hyper-v nodes running in cluster, each with 128 GB of memory, SCCM,SCOM, SCVMM 2008 R2 SP1, DPM 2010.

– request will come from a help desk or purchasing system, this is not clear yet.

before we start here is some notes for Microsoft guys working on that:

– I spent couple of days trying to figure out how sysprep can be done on the Linux machines and how to script it, the important note that Linux doesn’t has SID related information bounded to the machine, so copying the machine and renaming it will bring a totally new machine to the cloud. reference here.

– the machine name for Linux can be placed and configured in several places, keep in mind that if you used the command hostname to set the Linux machine host name it will be changed to the default name after the restart, to set it permanently, you will need to set the host name on /etc/sysconfig/network file.

– to execute commands remotely you will need to SSH on the machine.

now let us rock n roll:

I have no experience on Linux scripting so steps mentioned here are just guidelines and placeholders for others to use and kick off their implementations, however I don’t claim that those are the best way to do it.

the workflow you will configure will require the following:

– Create a template Linux virtual machine by creating a normal machine on any hyper-v Host.

– Install the Linux Integration components for Hyper-v, the main factor to note that you will need to install the development tools on the machine so it can successfully compile the source.

– after the integration tools installation you will need to assign a static IP to the machine (this will be used by Opalis later to SSH to the machine and run the configuration commands).

– Shut down the machine, from the SCVMM 2008 R2 admin console, copy the virtual machine to the library (if the hyper-v hosts located in different forest or DMZ this can be done by copying it).

now let us start:

– Install Opalis, best video can be found here.

– Import the SCVMM 2008 R2 Integration pack.

– Create the provisioning work flow as following:

image

the work flow will do the following:

– Create a random name that will be assigned to the machine, this is just a placeholder, the machine can be retrieved from text file, SQL DB..etc

image

– Create a VM from the VM template from the SCVMM 2008 R2 Server, and assign the name generated by the previous task to it, the name will be Linux-randomtextvalue

image

to assign the name linux-randometextname, in the vmname field you can pass the results of the previous task by typing, linux- then right click in the field and choose subscribe and choose published data and choose random text results from the previous step.

– the next step will get the vm, make the name as the name linux-randometextname same as previous step.

-the next step will start the vm, and pass the VM ID retrieved by the “Get VM” task, since this task requires VM ID, use the subscribe and published data to pass the VM ID from the “Get VM” Task.

– the link between the “start VM” and next SSH command will wait for 300 seconds or 5 minutes to allow the machine to fully start.

– the next ssh command will ssh to the static IP of the machine, and change the name by altering the file /etc/sysconfig/network and searching it for the default name “localhost.localdomain” and change it with the random text results:

image

the command will be : sed -i ‘s/localhost.localdomain/Linux-{Randome Text from “Generate VM name”}/g’ /etc/sysconfig/network

– the next step will configure the machine to use DHCP commands, same SSH step the command will be: sed -i ‘s/none/dhcp/g’ /etc/sysconfig/network-scripts/ifcfg-eth0

– the next SSH command will restart the VM to apply the settings.

and you are done.

again you can play with the workflow and create you own flow, there is some guides on the internet to automate the request that came from SCSM into Opalis..etc but this article to give you an idea about how generally the Linux machine configuration will be done.
