This is my first post in EE forums. We have a SBS 2003 which is running all the usual SBS services - in dual NIC configuration (please have a look at the Network diagram attached). As a BC perspective I attached a Buffalo NAS directly to the switch, added shares and security and a script which mirrors server's file shares to NAS on daily bases.
All worked fine until server was down. Within 15-20 mins no machines on LAN could access NAS or any shares on it. I am wondering what has happened and what do I need to do to make sure that NAS is available when server is down because thats the whole purpose of having it.
Thanks for your help in advance.
