hi simon

3 possible reasons see error: 53


 1. in server name using "/" rather "\" between server name , instance name,

     e.g. "server/instance" not correct. 
 2. name resolution server name not correct, "ping -a server" tell if that's case
 3. server machine firewall'ed , file sharing not in exception list. need put "file , printer sharing" in exception.
