Here is another great tip from Vincent Vlieghe over at the Virtrix Blog site.
As you all know, patching an ESX host is not exactly fun. VMware has promised to deliver a better patching system in their new version (ESX 3.1 and VC 2.1). In the meantime, we have to make sure that our ESX hosts are patched. In this post, I will use an IIS repository to deploy ESX patches from a central server (well, its not a push but rather a pull technology).
A special thanks goes out to Arne who wrote an article (in Dutch) on his excellent ictfreak blog on configuring IIS for ESX patches. I decided to use it and add a Perl script and a patchList to make the process more manageable.
