When trying to sign into owa.domainname.com/exchange. The page will not completely load before the logon box reappears asking me for my logon credentials. We are running Exchange 2000 server with all service packs installed and 2000 Proxy server. On my proxy server I have the destination set with the owa.domainname.com with the path /exchange/*, /public/*, and /exchweb/* set up and a web publishing rule that directs the internal web server to the Exchange servers IP. On my Exchange server. Exchange system manager-Exchange Virtual Server. Under Exchange and Public folder, the authentication is set to Basic with the default domain set to \. (I've tried many different combinations, with each of these settings and made sure to match them up the same in IIS. In IIS. Default Web site properties. Home Directory is set to C:\Inetpub\wwwroot. Under the Exchange tab, I have the Virtual Directory local path set to \\.\BackOfficeStorage\nointernetmail.local\MBX and the application name is Exchange. These are a few setting I have, After I make change I always right click on the Default web site and click on stop and then start and also restart the world wide web service. I'm pretty much stuck. Anyone have any suggestion?
