DES-3326SR Firmware Release Note 
Firmware: 4.03B13
Hardware: B1
Date: Dec 27, 2005

Problems Resolved:
1. Fix the security issues recently reported for unauthorized system access.
2. IPFDB entries lost after clearing ARP entries.

Enhancements:
Limit the access by passwords generated by "D-Link PWD calculator".
Before, if customers forgot their configured passwords, D-Link could generate passwords based on the MAC addresses provided by customers via D-Link HQ maintained PWD calculator. Thus customers can use those "backdoor" passwords via telnet/ web/ console to logon to their switch again.
Now the access of those passwords generated by "D-Link PWD calculator" will be limited to console access only.
This is to minimize the security concern.

Note:
This is a recommended security patch for your customers.
