[jcifs] SmbFile: BindException problem while browsing workgro ups

[Allen, Michael B (RSCH)]

So you run your program once, it works, but if you run it again within a short period of time it fails to bind that address? If so, it sounds like the OS is not releasing the socket from the last run.
Are you setting any properties like laddr or baddr? Try setting baddr to your broadcast address. Post a -Dlog=ALL if you still haven't figured it out.
