Hi
having the 404 issues as well with my SCCM install
now it appears that the CMApplicationCatalog folder for IIS is not being created hence the 404 reference
I have reinstalled the Application services and also tried the ASP. Net 4 enable command and still hasnt fixed it, im now out of ideas as i have followed all parts of the tutorial to this point
Here is the IIS Structure
It appears that even though i have the components installed i have no trace of logs or components in the system itself
Troubleshooting your Application Catalog
If your test is not successful, check the status messages for the following components - (does not exist in Administration > Monitoring > Component Status)
SMS_PORTALWEB_CONTROL_MANAGER
SMS_AWEBSVC_CONTROL_MANAGER
You can also check the following logs - (does not exist anywhere on the machine)
SMSAWEBSVCSetup.log
SMSPORTALWEBSetup.log
awebsvcMSI.log
portlwebMSI.log
EDIT: sorted it out had to run the commands in the log files manually after the services were removed so i could readd them
