Macs lose connectivity to Windows based DNS
Posted on 2011-09-14
We have two internal Windows servers acting as DNS servers. Both are AD domain controllers, the primary being a 2008 box and the secondary being 2003. When users attach to our network via DHCP the get both server IP addresss as their DNS.
We have been running some Macbooks using Bootcamp, and there is never a problem when they are on the Windows side. What we have seen though is that when logged into the Apple OS side, the Macbooks will lose connectivity to both DNS servers within 5 to 10 minuters. Renewing the DHCP lease will restore the connection but it doesn't last. Its very strange because they don't lose connection to the network - I can ping other IP addresses, but not those of the DNS servers. Any thoughts would be appreciated.
