Manually set Windows "Metrics" values for network cards. When a server has multiple cards, you are often forced to disable Windows' automatic "metrics", to make sure EPM traffic goes on the right interface.

# To use this script, rename LAN, BACKUP etc to match relevant network card names 
# in your environment (you can add or remove lines as well),
# and set values to match your metric preference (1 is the preferred card).

# All cards not mentioned here will be set to 100.

$cards = @{} # don't touch this line

$cards.LAN = 1
$cards.BACKUP = 99
$cards.MGMT = 98

# Don't change anything below, just copypaste.
