Thank you for your reply Eric!
The reason I am using two nics is because in my lab testing environment I have a DMZ vlan that I use for dual nic Netscaler /XenDesktop testing.
I have tried using the one nic option but for some strange reason, when i deploy it using the uagdeploy.ps1 script - the IP, Password, Hostname settings are not propagating to the UAG VM. I can't even logon to the appliance after it is deployed because the password is not being configured. From what I can observe, the configuration state of the NIC's remains set to DHCP instead of STATICV4.
Hope you can shed some light on the above.
