User Portal , Error

When I opened IE and try http://myserver enter user name and password. I’ve got an error message. Dashboard Error -2147024891 access is denied source : msxml3.dll What am I do wrong in installation. 1. install Window 2003 server 2. install IIS 3. install navision database server 3.7 4. install navision client 5. install C-front and test it ok. 6. install dashboard. 7. install user portal from 3.7 CD 8. make shortcut for fin.exe runasupas… 9. run a shortcut 10. run IE. Can I use database server and user portal application server in the same Machine? I use Client monitor to investigate. and I saw IE can connect to my server. Can anyone please suggest me the correct installation step? Thanks
