Answer: Here are some possibilities:

• A local target server was specified, and that server is not running.
  
  
• A HOST= network server address was specified, and that server is not running.
  
  
• The correct HOST= network server address was specified on the Network tab, but the ENG= server name is wrong.
  
  
• The wrong HOST= network server address was specified on the Network tab.
  
  
• Caution: If you change the HOST= value, you may connect to the wrong server if a different, but working, IP address was cached in the workstation file C:\Program Files\Sybase\SQL Anywhere 9\win32\asasrv.ini. To avoid using this cache file specify "DOBROADCAST=NONE" on the Network tab; e.g.: use HOST=ip-address;DOBROADCAST=NONE to force only that address to be used.
