Create 32-Bit system ODBC DSN with Powershell

This Powershell script creates a 32-bit system DSN on a 64-bit server. I got tired of manually creating DSNs for my VMware vCenter installations, so I automated the process. The only argument you need to pass to the script is the FQDN or IP address of your SQL server. If you don't pass any arguments, the script will abort with an error message.

I apologize for the line wraps, but I think its fairly obvious where the breaks are. You can change the $DSNName to be any name that you wish. $DBName is the name of the database on the SQL server. The script assumes the SQL 2008 native client is installed. If you use a different client you will need to modify the script a bit.
