update?
A: If the AutoUpdate utility downloaded one or more iDAT files before the
connectionloss,itwillinstall them into your existing.DATfilesandrecord
its failure to download the remaining iDAT files in its activity log.
Corrupted data
Q: What happens if one of the iDAT files is corrupted during download?
A: Before the AutoUpdate utility installs any iDAT file, it checks the file
against a verification checksum recorded in the DELTA.INI file. If the
checksums do not match, the utility does not install that iDAT file or any
subsequent files it downloads in that session. Instead, the utility will
display anerror message, then willdownload afull .DAT file setto update
your software.

Network configuration issues
Q: Do all the machines I want to update need to be able to connect to the
Internet?
A: No. You can configure one computer on your network to download the
iDAT files from the Internet, then have other computers on your network
download their files from this computer. To learn more, see “Three-stage
updating” on page 348.
Q: How can I prevent network bottlenecks when I update many
workstations?
A: The AutoUpdate Task Properties dialog box has a randomization feature
you can use to spread the network load. To learn how this works, see
“Enabling tasks” on page 223.
