Ok, I've switched between using FastCGI, both 32bit and 64 bit so often in the past 4(?) months that I am now at a complete loss as of what I am currently running.
7.5.7232.0 (fbl_srv_iis_dev(ksingla).090202-1706)
PHP 5.2.11.11 (Process tab says *32, so I would guess either FastCGI is running in 32 bit mode using the 64 bit extension, or I am running the 32bit version of fastcgi.)
I am fairly certain I used the 64bit version of 5.3 from the dev with no success.
