Yes, but those should be dissected by Ethereal as browser packets, not 
as SMB Mailslot packets.  Either there's a bug in Ethereal, or those 
packets *aren't* browser packets (or packets for any other protocol 
known by Ethereal), or perhaps the packets were captured with a 
"snapshot length" that caused the part that identifies the protocol 
being used (the mailslot name) not to be captured, or a non-standard 
mailslot name is being used for the browser packets.
