We are not running Exchange on the new proxy server, just win2k, IIS, and ISA. We are able to access OWA on the Exchange server from internal clients with no problems by addressing it directly: http://exchangeservername/exchange.; Problem is trying to get to OWA via the new server's IIS from external clients (http://newservername/exchange). We tried Ed's suggestion to login from an external client using "domain/account" as the ID and still got the 403 unauthorized error. We are using basic (clear text) authentication. >From: "Tony Hlabse" <[EMAIL PROTECTED]> >Reply-To: "Exchange Discussions" <[EMAIL PROTECTED]> >To: "Exchange Discussions" <[EMAIL PROTECTED]> >Subject: Re: Accessing OWA via a Proxy/Relay Server >Date: Wed, 27 Feb 2002 22:21:44 -0500 > >So you set it up as a front end/ back end deployment? > >----- Original Message ----- >From: "Alex T" <[EMAIL PROTECTED]> >To: "Exchange Discussions" <[EMAIL PROTECTED]> >Sent: Wednesday, February 27, 2002 4:24 PM >Subject: Accessing OWA via a Proxy/Relay Server > > > > Apologies in advance if this question is dumb or has already been >addressed > > in the archives or elsewhere--we are still Win2K/Exchange novices > > and >would > > appreciate some help.
