hgfs registry value causes issues with Terminal Services VMs

Jason Boche @ http://www.boche.net/blog posted a blog post titled : hgfs registry value causes issues with Terminal Services VMs

originally brought this up back in October with my Tip for virtualization Citrix servers invovling user profiles post. I’m bringing it up again because this week VMware updated their knowledgebase document 1317 Windows Guest Cannot Update hgfs.dat and it’s missing a piece of key information that administrators need to be aware of. I’m not going to rehash the whole hgfs registry value again. You can read the details about that in my October post linked above. The workarounds for hgfs issues caused by VMware Tools do work, however, what’s not mentioned is that a re-installation or upgrade of VMware Tools will re-install the hgfs value back in the registry thus introducing problems again. With the amount of ESX/ESXi version upgrades coming from VMware lately, which in turn cause VMware Tools upgrades, this scenario is not going to be uncommon for anyone who is virtualizing Terminal Services or Citrix. Add to that, VMware even recently released an interim VMware Tools upgrade patch subsequent to ESX 3.5.0 Update 3 (ESXe350-200811401-T-BG).

This is one of those things that is a good read, even if you are not running TS in VMware.

Thanks to Jason.
