Hi All, I have an infuriating DNS issue with Yosemite. Does anyone know what is happening or what might have been changed by Apple. Any temporary fix till Apple/Cisco get their act together? Thanks All! Below is the write up I sent to Apple via the Feedback Assistant (sent 9th Aug) There are major issues introduced in Yosemite in relation to resolving .local addresses to my companies DNS name server when connecting remotely via VPN. VPN client is Cisco AnyConnect Secure Mobility Client. I have to access autodiscover.MyCompany.local, mail.MyCompany.local and wiki.MyCompany.local constantly through Mail, Outlook and Safari however these URLs cannot be resolved and when pinged Network Utility states Unknown Host. Attempts to fix this issue involve Flushing DNS cache (sudo discoveryutil mdnsflushcache ), force quitting non responding processes (e.g. geod), constantly trying to ping the addresses, internet browsing, reestablishing VPN, quitting application etc. There is no sure fire fix. At some point the the DNS nameserver is then accessible by the OS and I am then able to ping one/all of the above URLs. Interestingly, it can start to resolve one URL such as Mail., but will fail to resolve another, such as wiki. There is no logical patten. There are DNS and perhaps port forwarding issues here and need urgent attention. I have addressed Mail by placing the IP address of my Exchange the server is accessible its just DNS seems to be broken. I cannot do this for wiki.MyCompany.local as the IP address forwards back to the URL and it then cannot be resolved. Whilst this issue is not persistent, it is consistent and happens at least every time I re-establish the VPN. It also re-appears randomly whilst on the VPN and can take 20mins to resolve each time. I have no idea what allows these URLs to sometimes resolve to my companies Nameserver and other times cannot. This issue happens with both IPv4 Tunnel Modes including Split Tunnelling. Through cat /etc/resolv.conf | grep nameserver, I can see the VPN assigns the correct Nameserver as the primary as soon as the VPN is established. The IP addresses of Nameserver and respective servers can be pinged. This issue needs urgent attention, as it will cause major issues for Corporate users. FYI - the VPN and DNS were running very well with the last version of Mavericks. This issue has been introduced in Yosemite. Some OS X network behaviours have been changed in this new OS.
