Via CCM, can you see if ypour services (SIA, Tomcat, services underneath SIA) are all up and running?
What about the Windows server event logs?
Can you ping adcsrv06.company.internal?
Can you telnet into adcsrv06.company.internal:8080
If ping or telnet fails you will not be able to connect to the CMC or BI launchpad-
A few things to consider:
Check your Windows firewall settings,
proxy settings in MS IE,
host.etc. entry for DNS,
and trust http://adcsrv06.company.internal in MS IE setting
Why and how did you change the port settings?
If you installed SQL Server Express for the CMS database during installation of SAP BI there should have been no need to configure ODBC afterwards! You might be better off cleaning your Windows srver, and do a complete re-install…eventually.
