[Samba] Error with winbind following Windows updates

[Rory Campbell-Lange]

Hi. We've just installed Windows updates on our Windows 2003 Domain
Controllers, and have the following issues on our storage server, which
is running Debian stable 2:3.5.6~dfsg-3squeeze5

    Jan 17 10:27:51 xxx smbd[2426]: [2012/01/17 10:27:51.286853,  0] lib/util_sock.c:680(write_data)
    Jan 17 10:27:51 xxx smbd[2426]: [2012/01/17 10:27:51.286915,  0] lib/util_sock.c:1441(get_peer_addr_internal)
    Jan 17 10:27:51 xxx smbd[2426]:   getpeername failed. Error was Transport endpoint is not connected
    Jan 17 10:27:51 xxx smbd[2426]:   write_data: write failure in writing to client 0.0.0.0. Error Connection reset by peer

We consequently cannot authenticate from the Domain Controllers.

We have the following settings in the header of our smb file:

    security = ads
    workgroup = XXXredactedXXX
    realm = XXXredactedXXX.LOCAL
    password server = XXX-dc1.haluk.local, XXX-dc2.haluk.local
    encrypt passwords = yes
    update encrypted = yes
    server string = XXXstorage
    netbios name = XXXstorage
    idmap uid = 10000-20000
    idmap gid = 10000-20000
    winbind enum users = yes
    winbind enum groups = yes
    winbind use default domain = yes
    winbind offline logon = yes
    enhanced browsing = no
    template shell = /bin/false
    veto files = /TheVolumeSettingsFolder/, /Temporary Items/, /*DS_Store*/, /*AppleDB/, /*AppleDesktop/, /*AppleDouble/, /Network Trash Folder/, /*Trashes/, /*TemporaryItems/, /*FBCLockFolder/, /*FBCIndex/
    delete veto files = yes
    create mask = 0775
    directory mask = 2775
    invalid users = root
    panic action = /usr/share/samba/panic-action %d
    log file = /var/log/samba/log.%m
    socket options = TCP_NODELAY
    printing = cups
    inherit acls = yes
    inherit permissions = yes
    map acl inherit = yes
    nt acl support = yes
    ea support = yes
    smb ports = 139 445

Assistance gratefully received.
