I\'m being driven to insanity trying to figure out why Intellisense just fails to work at all. The server I\'m using is local and is 2008, the database is set to 2008 compat
For SQL Server 2008 R2, installing Cumulative Update 7 will fix the problem. The file you need is
SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x86 or SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x64
SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x86
SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x64
I also had to uninstall and re-install SQL Server 2008 first (which didn't fix it, but the CU did).
