Security baselines and security health checks are an important part of any modern day infrastructure. These checks are done periodically throughout the year, usually ever quarter. In my opinion this is a good thing to check and make sure your security settings are following the guidelines that the company has set out to achieve. Here is where I do have a problem. When setting up the guidelines for the different technologies in your infrastructure it would make the most sense that the people establishing the guidelines need to fully understand the technology they are working with. After all, would you really want the midrange or mainframe group to write the policies and guidelines for the Microsoft Windows Servers in your environment?

Key challenges include the manageability and scalability of application servers. Innovations include the use of non-java languages like Groovy and Jython and even PHP and Javascript on JVMs, and the final demise of SQL as object caches offer more natural scalability.

I kept getting a pesky, “Disk is Offline because policy was set by an administrator” message. Microsoft’s website does not even know about this error message apparently. But the solution is a combination of websites. First you need to change how Windows 2008 sees the SAN devices, then you need to clear a readonly flag, then you are good to go.
Upgrade to vSphere – Virtual Hardware Updates
Well, as time permits I have been slowly upgrading my VMs to the latest virtual hardware. When I started this process, it was before VMware instituted a warning within the Upgrade Virtual Hardware that you first need to upgrade VMware Tools. This problem bit me twice and it was enough that I put in my own policy to always upgrade VMware Tools BEFORE upgrading the Virtual Hardware.
Persona Management – User Environment Management by Another Name?
They say there’s no such thing as bad weather – just the wrong sort of clothes. Likewise, there shouldn’t be such a thing as a bad user profile experience – its more likely you’ve the wrong type of profile solution.
