One annoying thing that I don't understand is that sometimes, after creating an instance, I can't remote desktop or browse to the machine, etc, even though I have attached a security group that allows these connections to the instance.
Strange, now it lets me in, but I have no idea what the Administrator password is. When I try to create a windows password for the instance, it says: "No password was found. There does not appear to be a generated Administrator password for this Windows instance. It is likely that this AMI has a built-in password known only to its creator. Please check the Log Output for details or contact the AMI owner." I check the log and I don't see anything resembling a password entry. And I am the friggin AMI owner
