Hi, Added addtional IP for ISA 2004 external NIC. configured listener on local host for published website and add OWA listener for second IP. OWA works fine at intranet (www.xyz.com/exchnage) However from internet (www.xyz.com/exchnage) It asks for the username and password and authenticates the users. The complete interface is show with inbox, outbox, sent items, etc., on the left pane and in the message section it shows "Loding" Pls advise. FBA is enabled on the OWA listener but when you type www.xyz.com/exchange the window prompting for username and password is usual one.why it doen't use OWa form? Regards, Prashanth
