Script to Hot Backup VMWare ESX Virtual Machines
I was searching for the best way to implement vmware-cmd to snapshot live VMs and then rsync them to another location of my choice and look what I found!
There is a free script called ghettoVCB.sh that does the trick.
The script allows you to backup live virtual machines and also maintains only a selected number of snapshots that you would like to keep. Check it out!
OCS 2007 Protocol Stack Error Event ID 14517 When Starting Services
Posted by Sheen in Windows Server on January 15, 2010
You may come across this error message when you install Office Communications Server 2007 for the first time in your environment. This error generally is seen after you run through the initial steps and are trying to start the OCS services for the first time.
This event ID will contain the following message:

This error can be misleading. The primary reason you see this error is simple – You have had a previous installation of OCS in the domain and there are still a few entries in Active Directory that haven’t been cleaned up even though you did a clean uninstall of OCS.
This is what you need to do to fix the error:
Using Rsync in VMWare
VMWare ESX runs a modified Linux Kernel. Sometimes, when you are doing basic administration tasks, you might find that there are certain Linux tools that you miss. One of the tools I miss most is the rsync tool. Its a very handy tool when it comes to data transfer. I searched high and low for a proper tool to do the job but never found one until now.
The problem with installing a standard Linux package into VMWare ESX is that it will almost certainly mean that you go down the path of installing a whole bunch of dependencies along with it and eventually something might stop working. The best way around this, obviously, is to compile a static package from source with all dependencies included.
KB974571 and OCS 2007
If you are running OCS 2007 or 2007 R2, do not install the patch KB974571. This patch is known to break OCS 2007 installations. In cases where the Office Communications Server 2007 has this patch, you will not be able to install the server and will get an weird error saying that the time is not correct or not in sync.
Here is the Microsoft KB article about this error.
Let me know if you have installed this patch and are able to run your OCS 2007 server without issues.
How to Backup and Restore Active Directory
Posted by Sheen in Windows Server on October 7, 2009
There are many documents written about backing up Active Directory but I didn’t find enough documentation that would help us restore Active Directory. So here is a guide aimed to provide insights into correctly backing up and restoring Active Directory.
Here is my mini how to – I have tried to keep it as simple as possible:
