das.allowNetwork1 didn't work as anticipated and now I can't get rid of the option! I get the dreaded "object reference not set to an instance of an object" when trying to clear it from the advanced HA options!
If VI throws this error one more time when I'm trying to do something simple, I'm going drive up there and spray paint it on the wall next to the VMware employee entrance! OK, maybe not, but I do have some choice words about this generic error and how often VI throws it at me.
Eh, just spotted this in the U3 release notes: "In previous releases advanced settings created on the Advanced Options page for an HA cluster cannot be deleted. Attempts to delete the advanced setting would result in an object reference error dialog box being displayed. This release resolves the issue and advanced settings can be deleted normally."
