*3.* Trying to select a domain user in order to add that principal to a
local security group (the object picker) would hang indefinitely.

*5.* Access to local file servers (EX: networked drives, etc.) are
extremely slow and sometimes did not succeed at all (appears to hang).
*6.* Internet connection problems.
*7.* Extremely slow file transfers.
