When a client migrates from a Windows 2000 domain to another Windows 2000 domain using ADMT (Active Directory Migration Tool), the migration log may contain:
E26126: Failed to move object CN=<UserName>, hr=800720e4 The naming context could not be found.
When you trace the error, you receive:
LDAP: ProtocolOp = ModifyDNResponse
LDAP: Result Code = Unwilling to Perform
LDAP: Error Message = 000020E4: SvcErr: DSID-031B02E2, problem 5003 (WILL_NOT_PERFORM)</b>
To workaround this behavior, specify lower case domain names Using the MoveTree utility to move objects between domains in a forest?
