When i used the findsmb script to list the machines on a network, the windows XP Pro machines doesn't were listed. I edited the script to see how it works, and I tested the nmblookup command with the '*' option on the shell and the XP machines don't apearred. If I starts the messenger service on XP Pro machines and run nmblookup '*' again the machines will appear. I think so the nmblookup command use the <03> type to list the machines, however i believe nmblookup should use the <00> type to list. P.S. sorry for my english
