The jTDS drivers may be easier to configure than freeTDS in your unix environment to allow database updates to windows. You have to compile the source yourself, but you would be doing in java rather than C. Here is a link to sourceforge:

jTDS sourceforge
If this doesn’t work, I have a version of the jar file that it would compile and also the subdirectories of compiled class code which I know runs at AIX 5.3:

jtds-1.2.jar

jtds-1.2.tar

The following example script will make a simple database connection and is pretty self-explanatory, it requires that the ‘net’ directory structure exist because I am not clever enough to figure out how to use jar files yet and I just un-jarred it with the -x command:
