Jim, that was it! We pointed SORTWORK to an alternate local drive and the SQL query worked. We no longer get the out of disk space error. However, were still at a lost to explain why one machine with 850 MB whould give out of disk space.

BTW, I hope this works for Eric, because you deserve some stars.

Thanks!
