This is happened to me recently. Same setup as yours but the specific DNS entry would fail from all workstations (XP/7/OS10.6). I never really got it resolved except for clearing the DNS cache as well. I hope a solutions arises...

At times (2/3 times a day) I am having to clear the DNS cache of our domain server because certain users would be unable to access certain websites such as for example HSBCNET.com. They can access other websites without any problems whatsover but somehow certain websites require the DNS cache to be cleared. Weird. Any idea what could be causing this to happen?
