Version 3.0 of the AST-4000 utilities is incompatible with AppleShare and
can cause server crashes. AST Utilities version 3.2 fixes the problem. Among
other things, it supports changing the SCSI address of the AST-4000. You can
use AST's product BBS (714-660-9175) to download the software and send
queries to the AST's Tech Support group.
