+1!! I've been manually updating the Railo/ms driver to the latest ms version, since as long as I can remember.
BTW, you can just replace the ms jar(s) in the railo lib folder, and remove the old ones, and then you don't have to use "other" to make it work (I've been doing that forever as well, without any issues.)
I used to use JTDS exclusively, but I've found the latest MS drivers to be better.
