Hi, as I wrote in a previous e-mail, we are noting different announcing between a w2k computer and an xp one (both professional). The computers are not trying to log on a windows domain, and this time I can provide also a dump of traffic thru ethereal. As you can see from the attached files, the win2k computer sends also the username (marty) along the network, and we cannot understand why. Is just a problem of a different implementation of the SMB stacks among different operating systems, or there's a specific reason for this behavior? Thanks, Luca & Luca
