Windows 2008 R2 DNS refuses to resolve certain DNS records

I have a client with a single Windows 2008 R2 Server running Active Directory. The server points to itself and all clients point to the server only. The DNS server is NOT configured with forwarders.

Recently it has failed to resolve certain records. mail.office365.com, and now www.bankofamerica.com.

The first time the issues happened mail.office365 would not resolve. Restarting the DNS service on the server fixed the problem. This time it will not resolve www.bankofamerica.com and restarting the service has no effect, nor does clearing the DNS cache using the DNS Management tool, or IPCONFIG /FLUSHDNS. I had to add an external DNS server to the forwarders list to correctly resolve www.bankofamerica.com.

Anyone know if there is a hotfix or something out for this?
