Cannot recreate all virtual desktops Error: "could not verify that the rd connection broker computer account has the appropriate permissions on the organizational unit

Hi, I have vdi set up, using virtual desktops.  I have recreated virtual desktops twice before, but this time, when I attempt to do so, I get the following error: "could not verify that the rd connection broker computer account  has the appropriate permissions on the organizational unit"

As far as I know, nothing has changed on the server, and AD is working properly.

I did check the OU in aduc, and edited the OU so that the server account has full control over the OU.

When I check the OU in collections/edit deployment properties, I get the following:

"The specified active directory domain services organizational unit is configured with the appropriate permissions to automatically create new virtual desktops"

DNS and AD replication are working fine.

Any advice will be greatly appreciated.

Thanks,

Kevin
