Today at home I’m setting up a vSphere 4.0 environment inside Workstation 6.5.2 so I can get more familar with the product. For my vCenter server I’m running Server 2008 R2 with SQL 2008 SP1 64-bit on my new 12GB i7 920 system.
I started the vCenter installation and got a message that vCenter Server system must have a 32-bit DSN. How do I create that? As it turns out, after a little Binging, the solution was pretty easy:
Run c:windowssysWOW64odbcad32.exe and create a System DSN for your SQL server.
