Picture finally scheduling the maintenance window for the ConfigMgr site update, getting change approval, and then the prerequisite check comes back like this:

Prerequisite Check Status
Prerequisite Status Server
Site server computer account admin rights Passed CM01
Firewall exception for SQL Server Passed SQL01
Microsoft ODBC Driver for SQL Server Failed CM01
Pending system restart Warning CM01
SQL Server process memory allocation Warning SQL01
Free disk space on site server Passed CM01
Required SQL Server collation Failed SQL01
Prerequisite check completed with errors. The update cannot be installed
until all failed checks are resolved. See ConfigMgrPrereq.log for details.
two failures and two warnings... the window is tonight. i dont want to start installing random things on the site server without understanding them.
