A Treasure Trove of Technology Tidbits
So, last week, I needed some assistance from VMware support. I used the feature available in the Administration menu | Export System Logs menu item to generate support logs. But, I did so while focused upon a host server that does not have any local host storage. Guess what happened? Well, without local host storage, […]
VMware’s vCenter server has some build-in alarms and alerting functionality. But, sometimes, a production environment wants to integrate with an existing solution or use a more comprehensive solution that also alerts when problems happen with physical servers. In any case, you might need the new solution to query the VMware environment, which is best achieved […]
By default, Exchange 2010 requires that users login with their fully qualified domain credentials. So, for instance, mycompany\julia instead of just using the login name. For many installations, there is only one Windows domain, and requiring the domain name to be entered is a little silly. How do you assume the domain so that users […]
So, I have local administrator and domain administrator rights, yet I cannot successfully open Microsoft Data Protection Manager 2010 (DPM) on my server. I searched the web and could not find a good answer to this problem. Since the error seemed to be a SQL Server error, my searches kept bringing me back to adding […]
So, the third party certificates on a 2008R2 Remote Desktop servers were about to expire. I figured, “Log into the certificate issuer website, renew the certificate, download the new certificates, and install them. How hard could that be?” Well, more complex than I first imagined. I updated the all the certificates using the various Remote […]
So, I am working on some HP 680c blades. They happen to be installed with four flex-10 modules in their blade chassis… which should result in 24 network cards per blade. But, something strange was happening because I could only see 13 network cards within VMware ESXi 5.0. While researching this problem, I came across […]
Several folks noticed that I used a third-party tool to attach an ISO image in a Windows virtual machine. Thought it might be valuable to comment upon the tool I was using. It is freeware and can be downloaded from this website: http://www.magiciso.com/tutorials/miso-magicdisc-overview.htm Once installed, mount an ISO image: Right-Click the “MagicISO Virtual CD/DVD Manager” […]
As many of you are probably aware, VMware 5.0 Update 1 was released on March 15th, 2012. I have had an opportunity to patch my ESXi 5.0 hosts and update the vCenter Server. This blog post contains the steps used to update the vCenter Server. Before you begin, gather the credentials you will need in […]
I was trying to debug poor performance issues at a customer running VMware. Noticed that they were running mostly Windows 2003 Servers, as opposed to 2008 or 2008R2 virtual machines. Considering that the newer operating system require more memory resources, I wondered at why the 2003 Windows Servers were having issues. Well, it turns out […]
So, I was looking through the system event logs of a 2008R2 SP1 server today. And, I found some error 57 several times followed by error 137. This pattern repeated itself every five seconds. The server was experiencing no problems other than this repeating error message. What could it be? Turns out that this error […]
