[Samba] Called name not present error, but only once!

[pisymbol .]

Hello:

I am trying to use the net time command to sync a server:

$ net ads time -S ale.hunt.com

(hunt.com is just for internal use only)

I see an immediate response like so:

>>> NBT Session Packet
NBT SessionReject
Flags=0x0
Length=1 (0x1)
Reason=0x82
Called name not present

"Called name not present" - alright but....

# nmblookup -A 192.168.17.53
Looking up status of 192.168.17.53
    ALE             <00> -         M <ACTIVE>
    HUNT            <00> - <GROUP> M <ACTIVE>
    HUNT            <1c> - <GROUP> M <ACTIVE>
    ALE             <20> -         M <ACTIVE>
    HUNT            <1b> -         M <ACTIVE>

    MAC Address = 00-01-6C-2F-1A-A8

If I do the same command a second time, it just works and continues to work
from then on. Nice. But why? The net command debug output seemed to
indicate it choose ALE#20 the first time it failed but that seems OK to me.

Why does the first call to 'net ads time' fail with 0x82 but from then
after, it just succeeds?

This only happens on the first call after the CentOS 6.5 x86-64 VM has been
rebooted.

# rpm -qa| grep samba
samba-winbind-clients-3.6.9-164.el6.x86_64
samba-winbind-3.6.9-164.el6.x86_64
samba-client-3.6.9-164.el6.x86_64
samba-common-3.6.9-164.el6.x86_64

Very weird. I noticed source (3.6-stable) has a few interesting comments in
this area:

858e63cab:


2948 /* This is the wrong place to put the error... JRA. */

Should I just try more than once all the time?
