New-ADComputer : A required attribute is missing

When trying to create a computer with this commandlet and you get this error, it may be a poorly worded exception. This error can come up if you don't have permissions to create computer objects on the OU you provided. If you follow the commandlet examples and provide what is required: samaccountname, name, and path; go check the OU permissions. If you had tried doing it with the older dsadd command, it will give an error that the modification was not permitted for security reasons. Once permissions are fixed, or a different set of properly delegated credentials are passed, it should work fine.
