bind 9.7.2-P3 does not resolve www.microsoft.com

[T. Wunderlich]

Thanks a lot for all your suggestions. I haven't found a solution yet, but found something 
which got my attention:

Have a look at the TTL of the following CNAME entries.

What happens when the lookup lasts longer than those 57 seconds? Maybe named will get 
in trouble then?

AND what do the RFC say about those CNAME chains? CNAME points to a CNAME?

As I wrote, my DNS server is quite busy and the trouble does not happen when it has no 
load at all (copied VM).

Thanks
 Thilo

PS: I circumvented the trouble with a forward of microsoft.com to my other nameserver 
(bind 9.3.2 btw) which is able to resolve it without a problem.
