All clients are configured as "P" nodes so WINS is a bit essential.  To bring it back I do a smb stp smb start and off it goes.  Now this is fine as far as it goes but any PCs updating at that time can get a little upset.  There are 500 odd smbd running at any one time.

> "VOYAGER#20" 983543441 44R
> I understand the #0x corresponds to the entry type but what is the 9 digit number to the right of that ?

The expiry time, I belive.

Not sure, but your not the first to ask...

The way I handle this is to use the 'dns proxy' option.  All my machines
are in DNS - and if then need to be found by name then the worst that
can happen is that nmbd does a dns lookup - finding the macine. 
(Unfortunetly this doesn't work for things like logon servers - but it
should do the job in your case).

> Another bottom line - Why can't my Samba daemons be as stable as my NT boxen (har har har) ? OK why does Samba not re-register occasionally (seems to be about a week, which is the final time out on an entry I believe)
