Can u suggest with instructions how I can go about fixing this please? I await your advice, and many thanks in advance. + 0 Votes Reponse To Answer robo_dev 1 year ago If DNS is not working, that's the problem.First check the TCP/IP settings of the network adapter. There are fields for DNS server which should show the IP address of the DNS server.Can you Ping the IP of that DNS server?Is this a clustered server? Is there only one network adapter in the server?Look at the event logs of the server to see if there are any entries that occurred about when things stopped working.Has this server been used at all for web browsing? If so, I would suspect a malware/virus issue. If this were a workstation the fastest fix would be to do a system restore back to a working state.Things to try:Clear DNS CacheUsing a command line Open Command Prompt. Type the following command and then press ENTER: Dnscmd ServerName /clearcacheAlso try restarting the DNS service on the server.http://technet DOT microsoft DOT com/en-us/library/cc754743.aspxAny recent changes to the network? A misconfiguration or duplicate IP address could cause issues. + 0 Votes Reponse To Answer jjohn 1 year ago Hi. Thanks for the replies. I have tried all your suggestions. Clearing Dns cache returns the error : command failed. RPC_S_Server_Unavailable. The Dns definitely is stopped and trying to restart it returns the error: windows could not start the dns server service on local computer. Error 14: not enough storage is available to complete this operation. Of course its not an issue of storage as the hard drive had 115gb free. The server is set as a local domain so the DNS settings are configured to 127.0.0.1, and it was connecting to the internet a month ago. The ip addresses have not been changed and the yes one can ping other network gadgets from this server and can also ping this server from other computers. Not sure about system restore as this is a Windows 2008 server. I will try to run service pack in the meantime but if you can think of anything else to try plz do help with suggestions. Thanks.
