Hey guys,
We have an automated pool of 150 desktops which get refreshed on logoff OR after being disconnected for >60 minutes. I've noticed that we have been gradually getting more and more "Agent Unreachable" status's for our VDI desktops over a period of 4 - 6 hours until I go in, remove the VM's from disk and let provisioning re-provision the VM's to reset them. Doing a desktop reset does not fix the issue. I have made sure that the VM's are receiving IP addresses from DHCP and they are. We are not running out of addresses since these 150 desktops have 250 IP addresses in the DHCP scope with 15 minute lease times.
We are running VMware View 5.2. If any more information is needed, just ask.
