samba - Jun 2003 - call timed out smbclient error on get command

hi im using samba to enable backup of nt server shares using the amanda
backup system.  however i am running into some problems.
even though i can use smbclient to connect to the share and browser
directories etc,  when i try and get a file i get the following error

    smb: \Administration\jill-andrew\jill-andrew\slide presentations\>
get "ppslides complete.ppt"
    Call timed out: server did not respond after 20000 milliseconds    
opening remote file \Adm                                     
inistration\jill-andrew\jill-andrew\slide presentations\ppslides 
complete.ppt
    smb: \Administration\jill-andrew\jill-andrew\slide presentations\>
Segmentation fault (core dumped)

through the amanda system i get the following error

    /-- william    //cytopia01.intra.cytopia.com.au/shared lev

    sendbackup: start

its more confusing because another share on the same nt server with the
same permisions doesnt give the same error.  you are able to get files
using smbclient.  however when running amanda i recieve the following error


    /-- william    //cytopia01.intra.cytopia.com.au/usershared lev 1     
STRANGE
    sendbackup: start
