When installing Configuration Manager, the most important tip I could give would be to make sure you install the SQL Server logs on a different drive than the database files. You really should install the SQL Server database Data files on D drive, the Logs on E drive. and then put SQL Backups on F drive. If this is not done, there may be several problems that will occur in Configuration Manager. For example, a common error is Management Point is not responding to HTTP requests. This error will manifest itself all the time if your SQL Server data and Logs are on the same drive. Another problem that I have seen on servers with SQL Server Data files and Logs on same drive is the Application Catalog will not function correctly. If you install SQL Server correctly, and do not install database files, SQL logs, or SQL backup on the C (system Drive), then there is a good chance that Configuration Manager will run successfully in the green for months. This tip is from personal experiences.
