Any hint on this topic?
Can anybody try to replace this behavior?
It's easy.

I performed also a ipconfig/flushdns to clean windows cache, but it =
didn't
work.
In Apache configuration files I use the DNS name 'dynlocation', but I =
look
at the error logs that Apache produces when the host can not be reached =
I
see that it is using the old IP.=20

I doubt apache caches the IP. I guess it's windows who is caching the =
IP,
check that possibility first.
