  • Unauthenticated network

    Hello Gentlemen, I need help, because honestly do not know what to do, please read the "unauthenticated network" in the TechNet forum, of my own, there has all the information from the beginning of the problem, you will understand my problem, there also put some pictures.

    Unfortunately this forum is not letting me post the post the link I put in the Technet website.

    Thank you!

    What about the Ladies - shouldn't they read it at all?

    Please post the link, with enough spaces to break it up so it doesn't become a URL

    And maybe a summary here so we can decide if it is worth looking for the TechNet post

          Sorry, but there is no way I would go to an obscured link - it could go anywhere - even if it is shorter than the real one
          Can you please post the TechNet link so at least we know which site it goes to. Since you now have 5 posts, you should be able to post live URLs

              I don't understand what problem you are referring to. It starts with a switch change and an authentication issue then finishes with a winsock reset. Your thread topic is "Unauthenticated network".

              What is your ACTUAL problem and question.
              1 1 was a racehorse.
              2 2 was 1 2.

                It is exactly what it says at the beginning of the post, the customer changed his core switch, then multiple computers (not all) began to show the unauthenticated network message on the network interface, I have reviewed all the settings of Switches, maybe intereferissem it, but nothing wrong was found, the network has 16 VLAN is not enabled autenticção of any kind, or 802.1x.

                We've now removed the domain machines and put again, has already been done reset of Socks, already updated the DNSUpdateProxy group user permissions on DHCP Server, but nothing worked, see the TechNet blog post that the images I show the unauthenticated network message .

                When this happens, the station can ping the DC server, but the server can not ping the season.

                If the computer is removed from the area and keep it only in workgroup, the message unauthenticated network some, but at the back of the field, a few hours later she returns.

                Important detail, making the test check the secure channel between the station and the server shows that the channel is established and working well.

                So that's it, no longer know what else to do, any ideas?

                Thank you!

                  Re: Unauthenticated network

                  How many workstations are affected? Are any servers affected?

                  Are the workstations that have the issue getting the proper DHCP address?
                  Can they contact and access domain resources?

                  (I haven't read the Technet post since there's too much info for me to spend time weeding through)

                    Re: Unauthenticated network

                    There are 500 workstations on the network, I believe that some 100 are affected.
                    They all take IP address correctly, in accordance with their respective VLAN, DHCP Server service is running on the primary domain controller, the servers are not affected, but only the stations.

                    Thanks !

                        They access the rcursos network, such as printers and shared folders, but sometimes happens to fail, usually what happens is blocking access to Internet and intranet portal.

                        Interestingly, when this occurs, the stations can ping the DCS servers, but the DCS can not ping seasons.

                          Have you tried a replacement core switch - if problems occur after the switch is changed (and presumably nothing else is), that strongly suggests where the problem is

                            More new information that caught with nets analyst of the client company.

                            Today in fact it is accounting for 18 computers with this problem, only that can happen to all these or some tomorrow no longer the problem, but others in other sectors so then is random, now has X number of computers with problems, tomorrow may be more or less.

                            It's very intriguing!

                              Hello Ossian, did not understand their placement, may explain again?
                              As the core switch can cause this problem?

                              It is a fact that the customer's network has 16 Switches the Allied manufacturer, each with a VLAN, all linked to a Switch Core from the same manufacturer, the Core has the complete routing table to communicate between VLANs.

                              It may even be the Switch Core, but I need to make sure!

                              Thanks !
