ISA, OWA, and Trend CSM Dashboard

Good morning all,

Getting ready to bring my new SBS 2003 R2 server live and really struggling
here to get things working and not really getting anywhere. I have one
client, and the server is connected to the internet using a non-published IP
address for testing (for short periods of time only, as this is NOT secure
with ISA turned off or misconfigured). I run the internet connection wizard
and disable the firewall and the client can access OWA and Remote server
management. Turn the firewall on (again via the wizard) and the client has
internet access, but no OWA - immediate login timeout without ever getting
the logon page. Same for remote server management. And basically I can just
forget about Trend's security dashboard - I'm not getting in there at all,
proxy error due to port being 4343. Found an article to use Security
Explorer, but that won't run? At any rate, clients not being able to hit OWA
internally tells me something's very wrong here to begin with.

Also, I'm occasionally getting errors that lock up the app when accessing
various tabs in ISA management console property sheets, so I'm figuring
perhaps I need to reinstall ISA, but before I do that I figured I'd give
folks out there a holler and ask for some advice, as ISA is a mystery to me
and I'm really not sure what I may have done wrong during the original
install - there were no errors.

TIA,

SusanV

 

BTW, the "one client" is in this lab environment - once we go live I'll have
27 clients in 2 subnets - another piece to the puzzle - Do I have to
configure anything in DNS or ISA to define the other subnet? The server is
in the 192.168.0.x subnet (as is my test client), and we have another
location using IP scheme of 192.168.1.x, DCHP has both ranges defined.

Thanks again,

SusanV
