This is a bit of a “gotchya” but more of a “RTFM” on my part. On some test XenApp 7.6 systems i’d setup when i’d put their delivery group into maintenance mode –> shut them down and do maintenance work noticed what i thought was rather peculiar behaviour when taking the delivery group out of maintenance mode as none of the systems would start by themselves. Trying Powershell wouldn’t help either.
Turns out it’s not supposed to be done for Server VDA’s only Desktop VDA’s.
So that explained that 🙂
