[Samba] Domain not available even minutes after workstation startup

Did you try disabling the media sensing feature? I need to look at some of my Active Directory XP clients and see if they are still getting the error.
I don’t think it prevented people logging on, and I am not using roaming profiles, so even if I still have this issue on occasion it might not be obvious. I think I had run into it when trying to deploy software through group policies. This was a few years ago but I think I had got it resolved.
You could try putting one of the problem XP machines on a 10 Mbit only link. Or maybe see if you can configure the NIC settings be be 10 Mbit OR 100 Mbit but not autosensing.

Thanks Gaiseric for the note.
I checked the XP Event Log, and the only error is:
Automatic certificate enrollment for local system failed to contact the active directory (0x8007054b). The specified domain either does not exist or could not be contacted. Enrollment will not be performed.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
The only suspicious entry in samba log: (I remember this could safely be ignored)
[2010/09/01 09:10:17, 1] smbd/session.c:111(session_claim) Re-using invalid record
The PDC was changed to connect via two bonded gigabit connection (balance-alb) in a mixed 1000/100 network few months ago. Contrary to the MS support link, we have problem with both 100Mbps and 1000Mbps connections intermittently.
Is any way to get XP to split out detailed log when it says "domain is not available"?
Is setting Winlogoncachedlogonscount the good way to avoid logon problem when network is not ready during initial bootup? According to MS, if the domain server is not available and logon data is not cached, "domain is not available" will occur.
Any further insight?

Did you check the event logs in Windows- they may provide some additional info.
This error sounded familiar- most of my users are in a Samba domain, but I have one group that uses Windows 2003 active directory domain. A few years back they had some weird issues that ended up being (possibly) related to the gigabit network connection. It had been hard to trace and had only been affecting newer machines.
I think the following link was relevant.

Yes, the PDC is also acting as the WINS server. The XP workstation is using WINS, set via DHCP (option netbios-name-servers <ip address of the PDC>;)

I have recently experienced an intermittent problem of getting

connected to a Samba PDC. The domain does not seems to be

minute or two,
to more than 10 minutes sometimes.
Is there anyway to speed up this process? Thanks!
I have set HKLM\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogoncachedlogonscount to 0 to workaround
of having the logon frozen (and folders not being redirected)
logon when the network is not ready.
