samba very slow

[Vincent Morlot]

Hello,

We use samba-linux with clients Workstation NT4.0 SP5. We
have one PDC samba and one additionnal serveur.

When we open files on the PDC all is ok, but when the files
are open or write on the other one, the access time is very,
very slow.

On the PDC we use debian 2.1 kernel 2.2.12 samba 2.0.6
On the other server debian 2.2 kernel 2.2.12 samba 2.0.7

After various search we have found that we have a trouble
with the netbios resolve name, without explain this.

on the two servers the value of the parameter name resolv
order in the smb.conf is the same = lmhosts host wins.

Or if we try the command

echo "test"|smbclient -M c010036 -dA
on the additionnal server

added interface ip=10.12.10.208 bcast=10.12.255.255
nmask=255.255.0.0
Client started (version 2.0.7).

c010036<0x3>
getlmhostsent: lmhost entry: 10.12.10.203 serveur3

on the pdc 

added interface ip=10.12.11.213 bcast=10.12.255.255
