Buenas tardes, tengo el siguiente escenario: modem Router ADSL de telecom pirelli, el mismo se conecta a un switch y ahi todas las PC. Todas las PC son: 1 W2003server con DNS y DHCP 5 PC con wxp *El servidor navega sin problema, pero las PC de escritorio me dice: sitio web encontrado y despues nunca navegan. (esto pasa si los datos se los pasa el DHCP) *Todas las maquinas navegan (esto sucede si les configuro las ip manual, respetando la misma configuracion que me dio el DHCP) en el DNS me da el siguiente error: event id 4011 The DNS server was unable to add or write an update of domain name qbandina in zone qbandina.asp to the Active Directory. Check that the Active Directory is functioning properly and add or update this domain name using the DNS console. The extended error debug information (which may be empty) is "". The event data contains the error. event id 4015 The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error. event id 4004 The DNS server was unable to complete directory service enumeration of zone qbandina.asp. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empty) is "". The event data contains the error. Igual estos errores los tiraba ayer hoy no, y hoy tampoco pueden navegar.Javier Peralta

This one may help. http://technet.microsoft.com/en-us/library/cc735696(WS.10).aspx (p.s. you'll need to reply in english for help here) Also post an unedited ipconfig /all from server and client may help. Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Hi Javier, No hablo español. I just use google chrome to translate what you're saying. But as Dave suggest check out that link provided. It could be a DNS problem. Make sure your clients is configured with a correct DNS settings. Have you tried to ping some websites like: ping www.yahoo.com if it shows request timed out, then you have no internet connectivity. if it shows replies but only your web browser doesn't display web page then check the web browser connection settings.(internet explorer option settings) also try at command prompt: ipconfig /flushdns Good luck! Every second counts..make use of it.

Thank you for responding, The Role of DNS delete it and put it back, but I'm still doing the same problem, and the only one marked as a warning: Event id 4521 The DNS server encountered error 32 attempting to load zone 1.168.192.in-addr.arpa from Active Directory. The DNS server will attempt to load this zone again on the next timeout cycle. This can be caused by high Active Directory load and may be a transient condition. If client configure the DHCP server to ping yahoo.com I do and I resolved the ip but then does not respond. If you configure the client manually with the same settings that gave me the DHCP, I can navigate without problem. Thank Javier Peralta

Check that DHCP Client service is started. Also post an unedited ipconfig /all from server and client may help. Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Good afternoon, I have the following scenario: ADSL Router modem telecom pirelli, it connects to a switch and there all PCs. All PCs are: 1 W2003server with DNS and DHCP 5 PC with WXP * The server no problem navigating, but no desktop, it tells me: website find and then never sail. (this happens if the data passes DHCP) * All machines sail (this happens if you manually configure the ip with the same settings that gave me the DHCP above) This began after promoting a new domain controller and demote another.Javier Peralta

Hi Javier, Thanks for update. So how did you implement internet name resolution for all these hosts ? Basically we configure forwarder on internal DNS server in order to forward the internet domain query requests from internal to external public DNS server. I assure you did same thing on your internal DNS server that clients are point to use , include the new prompted domain controller if you also installed DNS service on it. Meanwhile, if this issue only occur when obtains address from DHCP server, have you also updated the DNS entries for DHCP server/scope options after server retirement/promotion ? Have set other special DHCP options ? like WPAD ? Thanks.

If this server has the DNS role then you should put in static address (looks to be 192.168.10.5) of your DNS server and remove router address 192.168.1.1. Basically your DHCP server (looks to be router) must hand out static address (192.168.10.5) of AD server as primary DNS server address so clients can find DC. Then put the ISP's DNS addresses in the forward lookup of your DNS server so clients can find internet. Also make sure your server has static IP address outside of DHCP scope. (note google public DNS is shown for example only) Use your ISPs DNS or also check here for some you can use. http://www.dnsserverlist.org/ http://code.google.com/speed/public-dns/ Regards, Dave Patrick ....
