Virtual Center's customization process

Posted by tomarentsen on Friday 02 February 2007 @ 21:49 (526 reads) (comments? | Score: 0)

A while ago I have posted an article on how to use vbscript to clone a virtual machine and how to extend the customization: Cloning a VM using vbscript

At that time, I was under the impression that the virtual center customization part of the cloning process was done using Microsoft's sysprep utility. My impression was correct with one exception ... configuring the IP settings of the network cards !!!

What to do if you do not have DHCP enabled .. ?

Windows: Script to add DNS suffixes to a NIC

Posted by sebastien on Tuesday 02 January 2007 @ 11:00 (535 reads) (comments? | Windows | Score: 0)

Adjust the array with your dns suffixes and save as a .VBS file

DNSSuffixSearchOrder = Array("MYDNS1.COM", "MYDNS2.COM")
Set WMI = GetObject("WinMgmts://")
Set adapter = GetObject("winmgmts:Win32_NetworkAdapterConfiguration")
adapter.SetDNSSuffixSearchOrder (DNSSuffixSearchOrder)

Windows: Reload default security settings

This command will reload the default security settings for a Windows 2003 server. Can be usefull if someone else messed around or a wrong GPO was applied.

secedit /configure /cfg %windir%repairsecsetup.inf /db secsetup.sdb /verbose

Using Vmware Server to backup your ESX vm's

Posted by tomarentsen on Thursday 14 December 2006 @ 07:55 (597 reads) (comments? | Score: 0)

I was testing some of the scripts I have posted on this site with vmware server and they do work. A client I am currently working at is using Virtual Center for all of their VM management, this to avoid giving users access to the console and also to have a central place for the VI management instead of replicating shell scripts to each ESX.
Their VM backup solution exists out of file-level backup/restore done by a backup agent installed within the VM, but in addition they also wanted to have a backup of the VM's vmdk and their configuration files for quick recovery. Another requirement was that the backed up vmdk files should be located on cheap media (so not on a SAN).

Now while there are several third-party tools on the market that can do this for you, I have choosen for a far cheaper solution and purchased one VC Agent license for vmware server and clone the VM's to Vmware Server. Not only it is cheaper you also avoid introducing "another" product ... !!

Check out the download section, for examples on how to clone a VM. Also cold-migrations (part of the vmUtil.vbs script) do work as well.

SQL Server: Priority Boost setting

Posted by sebastien on Friday 08 December 2006 @ 13:46 (956 reads) (comments? | SQL Server | Score: 0)

By default, the priority boost setting is 0, which causes SQL Server to run at a normal priority whether you run SQL Server on a uniprocessor computer or on a symmetric multiprocessor (SMP) computer. If you set priority boost to 1, the SQL Server process runs at a high priority. This setting does not make the SQL Server process run at the highest operating system priority.

Based on actual support experience, you do not need to use priority boost for good performance. If you do use priority boost, it can interfere with smooth server functioning under some conditions and you should not use it except under very unusual circumstances. For example, Microsoft Product Support Services might use priority boost when they investigate a performance issue.

IMPORTANT Do not use priority boost for clustered servers that are running SQL Server 7.0, SQL Server 2000, or SQL Server 2005.

vmUtil.vbs ... yet another vbscript for Vmware (SDK 1.x)

Posted by tomarentsen on Wednesday 06 December 2006 @ 20:48 (578 reads) (comments? | Score: 0)

I have included yet another vbscript in the download section. The script can do vmotions, cold-migrations, snaphots and committing them.

Shrinking and extending volumes, even system volumes... (winPE 2.0)

Posted by tomarentsen on Wednesday 06 December 2006 @ 10:48 (1381 reads) (Read More... | 1811 bytes more | comments? | Score: 0)

This week I was looking at the new functionality of WinPE 2.0, one very interresting tool is the new version the diskpart utility.

There are some really cool new features, one of them is that you can format a drive from within diskpart (saves you another few lines in your scripts) but the coolest feature is that you can now extend and shrink all partitions even boot or system partitions.

Previously when you wanted to extend or shrink a boot volume, you had to create a new disk with the proper size, xcopy the content and replace the original disk with the new disk of your VM. While I guess everybody played with the extend option I won't cover that, but the shrink option is completely new.

Cloning a Virtual Machine using vbscript (SDK 1.x)

Posted by tomarentsen on Tuesday 05 December 2006 @ 16:04 (546 reads) (comments? | Score: 0)

Continuing on my previous article regarding programming the Vmware SDK 1.x using vbscript, in most cases it's unlikely that you are going to build new virtual machines from scratch, you rather clone them to speed-up the process so let’s clone an existing Virtual Machine using vbscript.

Windows: Access server locally using alias name failes

Posted by sebastien on Friday 01 December 2006 @ 10:51 (1879 reads) (Read More... | 1785 bytes more | 1 comment | Windows | Score: 0)

Error message when you try to access a server locally by using its FQDN or its CNAME alias after you install Windows Server 2003 Service Pack 1: "Access denied" or "No network provider accepted the given network path.

\servernamesharename

In this scenario, you experience one of the following symptoms:
• You receive repeated logon windows.
• You receive an "Access denied" error message.
• You receive a "No network provider accepted the given network path" error message.
• Event ID 537 is logged in the Security event log.

Note: You can access the server by using its FQDN or its CNAME alias from another computer in the network other than this computer on which you installed Windows Server 2003 SP1.

Additionally, you can access the server on the local computer by using the following paths:
• IPaddress-of-local-computer
• Netbiosnameor ComputerName
