samba - May 2002 - problem while connecting to samba when dialup connection is made

Dear

I have a problem with the samba 

When on or the win98 client connects in the morning for the first time 
when the internet is connected using ppp, the connection to the samba 
server fails. 

Samba version : 2.0.7

message found in log file

%%%%%%%%%%%%%%%
lib/util_sock.c: send_smb(759) 
error writing 4 bytes to client.  -1 . Exiting
lib/util_sock.c: write_sock_data(545)
write_sock_data : write failure. Error=connection reset by peer
%%%%%%%%%%%%%

I would like to make clear that the it is possible to connect 
immediately if the dialup connection is disconnected.

Also once connected for further connections there is no problem.

Regards
bye
