Exchange SP3 has now been installed and we have OWA working...yippee..but Now I get a password box for every graphic on the page which I assume is something to do with exchweb. I have set the authentication for exchange,exchweb and public to Basic and put in the domain name. I notice in the IIS logs that after the initial request, all subsequent requests are from anonymous so I have even tried to set up a allow all (temporary) Site and Content filter. Im not using SSL (yet!). I also notice that this doesn't happen to me but it does to everyone else including my system adminstrator who is also an Administrator. I think that I have logged onto the server in the past so I may have some kind of local logon credentials. I dont want to give EVERYONE log on local access as this is a DC. I tried only giving Internet users this privilage but it just stops everyone else from loging on. I have looked through this mailing list, but couldnt find a definitive answer.
