Hi

　　But when I execute “net ads join –U administrator at DOMAIN.COM” system response 
　　
    “[2006/10/20 09:21:41, 0] utils/net_ads.c:ads_startup(281)
     ads_connect: Response too big for UDP, retry with TCP”
   why I got this message? My host can’t join AD 2003.
   Who can help me ?
Best Regards,

Alan Zhou
