Winbind errors "Can't contact our the NETLOGON pipe"

[Dina Fine]

Hi

I have the following problem with the winbind in samba 3.0.20 in mixed
Active Directory environment.

Sometimes the winbind doesn't raise well with the following error "Can't
contact our the NETLOGON pipe"

[2006/06/04 14:36:03, 3, pid=22687]
nsswitch/winbindd_misc.c:winbindd_dual_list_trusted_domains(124)

  Can't contact our the NETLOGON pipe


In such a case every authentication against the active directory fails.

Usually the second restart solves the problem.

Any help will be appreciated.

Here is the configuration file:

        idmap gid = 51000-64000
        idmap uid = 10000-50000
        lock directory = %$(lockroot)/config/samba/%$(SAMBA_SERVICE)
        log level = 3
        machine password timeout = 999999999
        name resolve order = lmhosts wins bcast host
        netbios name = twister
        password server = kenguro
        pid directory = /tmp       
        security = domain
        use mmap = no
        winbind separator = +
        wins server = x.x.x.x
        workgroup = workgroup
