Name:           Query-UserAccountControl.ps1
Description:    Exports an individual CSV for each UAC Flag all User and
                Computer accounts. Assists in identifying accounts with
                specific configurations such as Kerberos Delegations.
Usage:          .\Query-UserAccountControl.ps1 [-Server <domaincontrollerfqdn>]
                .\Query-UserAccountControl.ps1 -Server "dc1.contoso.com"
                Simply execute the script in the folder you wish to generate
                the .CSV files into. Results will only include accounts the
                executing user has privileges to read the userAccountControl
                attribute of.
                If the server is in another domain, the calling user must also
                have privileges to query that domain.
