Teaming 2x 1gbit network adapters with the HP utility usually dosnt take much more than a few minuts

alltho, this time a strange thing appeared.

both nics was connected to 2 different switches with identical setup, and both showed up as connected with an ip.

after using the utility to team them up, the new virtual nic showed up as “network cable not connected” and checking with the hp team utility, the teaming was broke, even tho the virtual adapter were still visible.

after abusing google for quite some time, i finally found a KB solution here

for some reason, a few values in the registry was disabled (was enabled on a few other servers i checked)

as the kb describes, do the following (and remember to reboot before teaming again) ->
