I have an internal server (not front end) running OWA and everything works fine with one exception. &nbsp;When we log in we have to log in first to the OWA server, then a second time to the Exchange server. &nbsp;I believe there is a way to change it so that we only need to log in once, but I can't sort it out.<br />
<br />
We're on Exchange 2003 running on Windows 2003 servers. &nbsp;The OWA server has no active mail stores, it's only used for OWA. &nbsp;<br />

Thank you for any advice.<br />
