If the account is in the parent domain:
1359 : An internal error occurred
Please consult your system administrator.
Note also that a GC server is required for logon in all cases, except when there is only a single domain, the child domain is in Mixed mode, or the user is the administrator. However, it is not recommended to operate without a Global Catalog server as there are some services and applications that require a GC to function, for example, Windows Address Book and Exchange 2000. WAB can be configured to point to the AD's LDAP port of 389 but defaults to the GC port 3268.
