However,the Microsoft WINS implementation makes a couple of changes to the RFCs:/p>ul>li>eliminates the NBDD completely/li>li>only registers individual computers in the Internet group 0x1c/li>/ul>p>The NBNS implementation in Samba (nmbd) followed the Microsoft guidelines, so is not completely suitable foruse in an OS/2 environment.  Without these features OS/2 is unable to perform domain location functionsacross IP subnets, which among other things prevents OS/2 client logons to domains (both OS/2 and NT).  Thepatches provided here add functionality to Samba to allow full OS/2 support in a NetBIOS over TCP/IPenvironment:ul>li>implement NBDD functions/li>li>register individual members of group 0x00, as well as 0x1c/li>/ul>p>The above two changes are enough to fix the missing OS/2 functionality.  Two other changes are made as well:/p>ul>li>fix Sambas parsing of datagram packets/li>li>add a parameter to extend NBNS ttls beyond what is negotiated with the client/li>/ul>p>The former is a Samba bug, it treated all datagram packets the same, while the datagram types used by theNBDD have a different structure.  The latest change is a workaround for what appears to be an OS/2 problem.When a system registers its name with an NBNS it negotiates a TTL with the NBNS.  Before the expiration ofthat TTL the client should refresh its name with the NBNS.  Over time OS/2 systems appear to lose sync withthe server, and dont refresh their names until after Samba has deleted the name from the list.  Theparameter added tells Samba to wait past the expiration time before deleting the
