This problem can occur if the ISACTRL service fails to read the packet-filter configuration (DHCP Client or DNS or ICMP filter), when it tries to convert an empty string (Remote IP Mask attribute) to an IP address.

RESOLUTION

This problem was corrected in Internet Security and Acceleration Server Service Pack 1.
