Hi, This week I installed the latest MS updates for server 2003. After I rebooted the server tamino would not work. The XTS directory server service was crashing on startup in ntdll.dll. I was running 4.4 instaleld on top of 4.2. I uninstalled the MS updates but the service still crashed. I took all the tamino installations off the machine and reinstalled 4.4 and it seems to work OK. Is this a known problem or was I just unlucky ? regards Doug Young
