These are VDIs running Citrix XenDesktops. I just saw that in VSphere it was showing as 2 IP addresses. Could it be due to outdated VMWare tools, or why would this show like this?
check the vms, do you have ipv6 enabled on the network interface, if so turn it off.
vcenter will show what windows report. Fe80 I beleive is the same thing as 169. local addresses in ipv6, which windows auto assigns if you don't have a dhcp or static address set.
