after upgrading view to 5.2 , linked clones pool fail to provision desktops

Hi all

I hope someone has an idea,

i was running 5.1.1 environment including composer, and deployment was working with no issues.

After upgrading to 5.2 (including composer) and the agents on the parent vm the linked clones deployment fails.

the vm's are created but the customization fails, if i do log in to them, i can see that there is no nic. which is weird.

now the vm does of course have a nic, but for some reason the os does not see it.

I am using windows 7 64 bit and vmxnet3.

if i revert to the old agent 5.1.1 it works.

Does any one have a clue?

Thanks
