Hi  all. 

One of the banking domain www.services.online-banking.gslb.sabbnet.com
<http://www.services.online-banking.gslb.sabbnet.com>  unable to  resolve
with  our primary namservers 212.119.64.2 whearas as my another server
212.119.64.3 is ok

In addition to that when I dig with +trace the query is responded. Without
the +trace. Connection timed out errro. 

Any hint would be highly appreciated.. 

[root at ns10 ~]# dig www.services.online-banking.gslb.sabbnet.com +trace, it
responded well..
