Topic: SMB connection lost

[Michael]

I'm encountering a strange problem with lots of lost connections which are, in fact, not really lost. I don't know whether it's related to my network's configuration or Samba or e-smith or even none of them. Voilà my configuration:

Server: e-smith 5.1.2, Via C3/800, Realtek 8239 10/100
Client: Acer TravelMate, Windows 2000/98se, D-Link dwl-650 (wireless)
Accesspoint: D-Link dwl-1000ap

Normally I transfer data with 600-700kb/s which is imho ok. But Windows often pops up the "connection lost" balloon in its tray. When I open Explorer it only shows the offline files (don't know its exact name in the english version) on my network shares.

But while my server seems to be disconnected I still can surf on its web pages, listen to music streamed by this machine using http or even transfer files using ftp with up to 700kb/s. Internet access (my server is configured as gateway) is working, too.

Pretty impressed by this I connected to the office using a Nortel VPN client installed on my laptop. And yes: no problem accessing Windows shares using this tunnel. Another test showed that I still could access my other computers shares in the network. Only my server's samba shares are still unavailable.

Does anyone have any idea?

Regards,

Michael

A friend of mine is running a SME v5.1.2 (which was upgraded from 4.1.2, to 5.0, to 5.1.2) server with Samba 2.2.7,  setup as gateway/server for small LAN of 10 Windoze client machines.  Recently he has been getting network share "hangs" from his Windows 2000 client machines...or at least that's what he tells me.  He hasn't mentioned if proxy, ftp, mail services are still working when his network shares can't be found.  I'll have to check with him, but this seems somehow similar to your issue.  He said that he has been  restarting Samba service to fix each time.

SME needs to be in Domain Controller mode to be a WINS server. Then use DHCP don't use static IPs on the LAN

hope this helps

This symptom is consistent across the NT derived O/S's and is due to some of the default settings of the network redirector.  I have put in a lot of time researching the underlying causes.  I have produced a page detailing my results & providing a couple of .reg files which will cure the problem.  The one you need is NtWrkStn.reg and you can find it here:

may be it's still a little early... I'm currently trying your registry settings. And they seem to be promising. There's two concurrent copy sessions: one large CD image (350MB) and a folder with some thousand small html and gif files. Even opening a large StarOffice file (120 pages, many images) does work. And all this with some (so far unknown) 750kb/s!

Thank you anyway: this let's me hope (and already 15 minutes without interruption...)

Nick, thanks a lot for saving my faith in my WLAN configuration! After applying your registry hacks I did not have any more interruptions for more than 6h.
