DSS Address Book access for latest generation devices
HP's latest generation devices, starting with the HP ScanJet Enterprise 7000n Document Capture
Workstation, HP M4555 MFP and HP Color CM4540 MFP, now access the DSS Address Book by
connecting directly to the SQL database (which is running on the same server as DSS).
Hostname resolution
DSS 4.91 supports the use of hostnames for server addresses. Depending on the configuration of the
host machine, DSS 4.91 will use NetBIOS/WINS (port: 137, 138 or 139)) or DNS (port: 53) for
hostname resolution.
