Hello, I would like to know if it's possible to execute a windows command like : Code: ipconfig /flushdns On Windows, i must launch the console (cmd) and execute this command. But with Wine, it's possible? Thanks

...ests on the wiki, everything is working fine. Then I pull the plug on my first DC and no one can log on. And this time I waited far longer than the suggested "refresh interval" of 15 min - even longer than the value called "TTL" in the GUI of 1h. I also tried "ipconfig /flushdns" on my windows client. Does not improve the situation. Only a reboot solves the issue. But that would be no acceptable practice for Linux member servers. And it doesn't seem to help, anyway (just tried this).

...nyone shed any light on this one? Is there another network level diagnostic or reset I can run to see what''s going on between the browser and the webrick server? OS again is Windows XP. [1] hosts file is good 127.0.0.1 localhost 127.0.0.1 www.mycookbook.com [2] ipconfig /flushdns => didn''t help - this wasn''t the command I had found previously that made things work I don''t think (i.e. the one which I now can''t find on the net) [3] Windows XP firewall is off, and I''ve deinstalled zonealarm [4] Also if this helps here is an...

Hi, I think I have network issue on my XP PC here trying to run up InstantRails and using it. I create an application and run up the server "ruby scripts/server" and it runs up, but then when I try to browse to it the browser just sits and spins and doesn''t connect :( * I''ve tried: localhost:3000, 127.0.0.0:3000, 127.0.0.1:3000 + the IP address that

I've a server running CentOS 5, Samba 3.0.23c and OpenVPN-2.1beta4 A laptop running Vista connects to the server over VPN. The CentOS server is local, domain and preferred master, and also WINS server. It looks like every once in a while the Vista laptop drops the VPN connection, which gets re-established soon after that. But the problem is, it appears that after the dropout the Vista

Hi, I tested the AD (Samba4) domain log-in on Windows 7 clients and Linux member servers with my PDC being offline (plugged the cable). It is not working so well. On Windows it initially takes forever. It works again after rebooting the client, which seems to be the easiest solution (can be performed by the user). On Linux member servers, ssh log-in eventually times out. It works again,

...gt; > Is this due to DNS and kerberos timeouts accumulating? It is DNS related. > What is the best way of dealing with this? The *best way* is a HA solution for your DNS Servers, but its expensive. The DNS client (resolver) caches the srv records for 15 minutes aka 900 seconds. ipconfig /flushdns drops the cache. Reboot does the same. On server side you may set shorter TTL for the server records, but then you have more DNS traffic. On small netwoks (sites up to 20 clients, no wifi) I have good experience with a TTL of 180. > Best, > Ole -- Gruss Harry Jede

...the records get updated properly. I am also able to forward- and reverse-lookup the node. I just did a complete Wireshark dump of a gpupdate process on my Windows 10 machine too. You can find it here: <https://dl.dropboxusercontent.com/u/2015365/gpupdate.pcapng> I also did an ipconfig /flushdns just before the capture. Thank you Rainer
