Hi,
i have some strange problems with a windows-2003 server,
and a share i want to backup via samba.
In the amanda report i get this error:

> FAILURE DUMP SUMMARY:
>    LIN002 //172.16.8.42/dfs lev 0  FAILED "[disk //172.16.8.42/dfs, all estimate 
failed]"
>

and on the sambaserver, which should do the backup, i get this as 
sendsize.debug:

i have never seen such an effekt in all the years i use amanda.
what could be the cause of these Error?

Permisions?

i should mention, that this machine behaves a little strange with 4 other shares
backuped directly with the latest zmanda-windows-client.
It only gives me backups containing each and every file in the shares, even in 
level 1 runs.

As these a shares make up about 60% of the data to be saved (~400GB) these 
oversized incremetals
blow up completely the planed volume for my virtual-tapes.
has anybody out there a clue where i should search for?
Thanks
Christoph
