How about testing the same system with > a wd8003 for a day or so (just lend it from someone). Firstly: I know no-one with a wd8003. Second, telnet and ftp seem to work. I guess that ftp transferring large files must hammer the ethernet as hard as anything will: and the amount of network traffic is much larger during ftp's than during the locked-out condition: in fact the network traffic while locked out is really quite slight. (I am not analyzing anything fancy: I have stuck a 'scope on the ethernet cable.) I remain mystified... Simon --- "A thousand violins cloy very rapidly without percussion" John Fowles
