For the first time in a while I've found a "gotcha" between the CLI & the VMware Infrastructure Client.
When we did the updates the the latest ESX patches as of middle of June 09, the version # from running vmware -v and checking in the VIC client.
CLI version: 3.5.0 build-169697
VIC Client Version: 3.5.0, 163429
A friendly warning that build numbers don't match to any scheduled release anymore.
