  1. [Samba] The specified network name is no longer available 3.0.25 RHEL4


    I have a reproducible intermittent error large site - "The specified network name is no longer available".

    This happens when copying large files. Below is part of log level 10 output& strace. Sorry for the long posting. I will probably need to put the loglevel 10 attached to a bugzilla - but thought I would try the lists initially.

    RHEL4
    samba-3.0.25b-1.el4_6.4
    openldap-2.2.13-8.el4_6.4

    Sometime using pdbedit -Lv username reports "ldapsam_getgroup: Did not findgroup" I am wondering if this could be related to the problem. In debug level 4 something that stands out to me is " string_to_sid: Sid adrians does not start with 'S-'." This is intermittent.
