Dear all,
  I have a linux server that uses redhat AS4.I want to make a samba file
server.Because we have a windows 2003 domain,I must use "security =
ADS".The samba version is samba-3.0.10-1.4E.9.
  The samba server joined windows 2003 domain successful.I can find samba
server in the "network neighborhood".Client PC access samba server must
confirms with PDC.The domain member can access directly.
  There is a problem that sometimes client PC can not access the samba
server.The hint is "can not find network path".I check samba server logs
and find following error :
   [2007/04/28 13:53:58, 0] lib/util_sock.c:read_socket_data(384)
  read_socket_data: recv failure for 4. Error = Connection reset by peer

  Under is some config files.They also in attachment.Hope you can help
me.Thank you!

*****nsswitch.conf*****
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# nis or yp  Use NIS (NIS version 2), also called YP
# dns   Use DNS (Domain Name Service)
# files   Use the local files
# db   Use the local database (.db) files
# compat   Use NIS on compat mode
# hesiod   Use Hesiod for user lookups
# ldap   Use LDAP (only if nss_ldap is installed)
# nisplus or nis+  Use NIS+ (NIS version 3), unsupported
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files ldap nis
#shadow:    db files ldap nis
#group:     db files ldap nis
passwd:     files winbind & szlig
shadow:     files
group:      files winbind & szlig
#hosts:     db files ldap nis dns
hosts:      files dns
# Example - obey only what ldap tells us...
#services:  ldap [NOTFOUND=return] files
#networks:  ldap [NOTFOUND=return] files
#protocols: ldap [NOTFOUND=return] files
#rpc:       ldap [NOTFOUND=return] files
