<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">Thanks a lot for all your suggestions. I haven't found a solution yet, but found something
which got my attention:</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">Have a look at the TTL of the following CNAME entries.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">What happens when the lookup lasts longer than those 57 seconds? Maybe named will get
in trouble then?</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">AND what do the RFC say about those CNAME chains? CNAME points to a CNAME?</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">As I wrote, my DNS server is quite busy and the trouble does not happen when it has no
load at all (copied VM).</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">Thanks</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"> Thilo</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">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.</span></font></div>
