I finished installing WP3.3 with multisite. It seems to work fine. However, when I create a new site I get a 404 error when I visit it or goto the dashboard.
I tried this twice and read many forums. I am hosting at Godaddy and have a dedicated DNS (for domain mapping). Before I try to get the domain mapping up and running I thought I would create a test network site called testsite001. Whenever I click on visit or dashboard I receive an 404 error. The browser address shows http://mysite.com/testsite001. I updated .htaccess per WP. It was placed under a directory named \home\content\56\.....\html\ with the blogs.dir. I changed the permissions on the \home directory to 755. When I look at the properties again it shows 705. Should owner permissions, group permissions, and public permissions all have read, write and execute privlages?
There may be an issue with the directory structure within the installation. Unless the path shown in the browser's address bar is virtual or unrelated to the directory structure within my domain, I do not see subdirectories at my domain that match the browser's address bar. I could tell this by looking at my domain using my FTP file transfer program.
Have a great day.
