cluster file server in azure

hi

i am trying to create a clustered file server on top on Storage Space Direct 2016 cluster and it fails after long waiting.

if i pre-stage fileserver in AD and disable, give the cluster object permissions on that object, it errors saying the object already exists in AD. if i don't create AD object, it fails after 10minutes and not AD object gets created.

i have tried full domain admin permissions, given cluster object " create computer objects" permissions on the OU without luck.

any suggestions?

thanks

TA
