Hi all,
userprincipal.changepassword(oldpassword, newpassword);
gives error: that is Configuration information could not be read from the domain controller, either because the machine is unavailable, or access has been denied. (Exception from HRESULT: 0x80070547)
but userDirectoryEntry.invoke("ChangePassword", new object[] { oldpassword, newpassword });
userDirectoryEntry.CommitChanges works fine.
Any one please tell me the reason behind this.
