for the server parameter use

 

"servername","folder\\subfolder\\db.nsf"

 

 

the servers have to have a trust relationship established via the server documents for this to work. 

 

 

 

var dbName="APPSERVER01/MARKETING!!/development/test/db.nsf";
var key ="John Smith";
var x=@DbLookup(dbName,"By Employee Name",key,3,"[FailSilent]");
return(x)

 

 

 

(XPages/Javascript w/@Formula)

 I'm pretty sure the first variable to the db @ Functions will only take an array.

 

So the server and database reference have to be separate strings.
