Re: [Samba] netlogon sometimes works (corrected with smb.confattached)
Hi Kurt, thanks for that. Our ping times are faster than that, I have now created the server without any extra software running (we were running domino on the box as well), so now it is purely a fileserver, running backup DNS, DHCP, NIS, NTP. If I turn my PC off, and log on it executes the NETLOGON script each and every time (great!), alas, if I log out and log back in, chances are it won't work (not so great), if I persevere, it will eventually work again, for a while. So, even with less load, it occasionally works, though I am perplexed as to why it appears to always work when I reboot my PC, perhaps there is something in windows that it messing up? We run Windows 2000 at the moment and are waiting to launch Windows XP on the poor users in the near future.

Re: [Samba] netlogon sometimes works (corrected with smb.confattached)
John, I have no success with packet sniffing, the netlogon share either works or it doesn't. Our boxes are not overly loaded, but I took your advice and tinkered with the loading. Over the passed week, it gets the netlogon share executed more times than not (at the moment) but it still isn't perfect (100% record is what I'd expect from a PDC). I suspect it is a problem within samba in terms of how fast it looks at certainincoming network packets, as the password logon works fine every single time, but connecting to the PDC and executing the NETLOGON share are problematic.. Anyway, thanks for your help. Hopefully, a bit more load balancing will get it working 100% of the time.

You should use a network sniffer (like Ethereal) to capture a trace of a logon that works correctly and one that does not. Then examine the differences to find what went wrong. It should tell you where things broke down. If timing is the issue t hen your authentication server may be problematic. In this case you would need to either isolate the problem, or move the authentication (netlogon) service to another machine that is more responsive. - John T.

I tried hardcoding it into the network card's settings, ensured the settings were there (ipconfig/all) and it did work on the first occasion. Subsequent logins, fail to make it run the netlogon script I've tried turning debug up but the output doesn't make much sense, had it mentioned attempting netlogon share, failed due to... then I'd at least be in a position to understand it. But the problem is intermittent and not mentioned in the logs (except when it succeeds) John H Terpstra [EMAIL PROTECTED] 20/01/2003 17:19 To:[EMAIL PROTECTED] cc:[EMAIL PROTECTED] Subject:Re: [Samba] netlogon sometimes works On Mon, 20 Jan 2003 [EMAIL PROTECTED] wrote: Could anybody please help?
