*1 When obtaining user groups, check the following:
• The user account that can obtain user groups is sAMAccountName (user). Do not use
UserPrincipalName (user@domain.xxx.co.jp) as the user name.
• Check whether the name in "Group" is correctly specified including the case-sensitivity in [Settings]
[Machine Features Settings] [System Settings] [Administrator Tools] tab [User
Authentication Management] [Windows Auth.].
• Select the user in the address book, press [Edit], and then check that [User Management / Others]
tab [User Management] [Available Functions / Applications] check box is cleared.
• Check whether "Global Scope" is specified as the scope of the group in a property for the user
group created in DC, and the group type specified in "Security". Also check whether an account is
registered to the user group that has been created. If more than one DC exists, check whether a
trust relationship between DCs is established.
*2 To resolve the domain name, see the following:
• Check whether [Domain Name] and [DNS Configuration] or [WINS Configuration] is specified
correctly in [Settings] [Machine Features Settings] [System Settings] [Interface Settings]
tab.
