I'm open to field any other possibilties. What is the length of time involved? You say you have replicated the problem from both W2K and Solaris clients but I'm still curious as to what is between those systems and your FreeBSD system. Guessing the FreeBSD system is at home on DSL or cable modem? A number of ISPs have what are supposed to be transparent caches between their users and the internet. Sometimes they really are transparent. Sometimes not. A friend had a heck of a time with ftp and ssh into his home computer on @home, then magically one day the problems disappeared. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
