I have an interesting Problem with OWA with IE (Win2000, Exchange 5.0, IIS, the PC is also a ADS-DC). The user don't see the middle Frame (.../username/inbox/?cmd=contents) in OWA, and the Login-Window comes again and again, till it comes not and in the Middleframe stays "Loading". Log-Files on Server: 401.5 Error(ISAPI/CGI Authorization Error). Strange is that it has earlier worked, and with Mozilla/Firefox works even now, so it is not a Problem of too much Security, imho. Sometimes works even in IE, if one have tried 20-30 times, and works then for some time. I couldn't see any dependency to Windows internal authentication over IE. Could somebody please please give an advice.
Thanks a lot,
