For example, for a simple php file: <? echo gethostbyname ("smtp.cpttm"); ?> When it is run, it tries to lookup smtp.cpttm using the old DNS server (I know it using tcpdump). The new DNS server is specified in /etc/resolv.conf. If I issue "ping smtp.cpttm" in a command prompt, then tcpdump shows that it is accessing the new DNS server. Any idea? Thanks. Check /etc/hosts Try doing the same thing from the command line. And did you re-start apache so PHP could "forget" any DNS entries in any cache it might have? There may be something akin to clearstatcache for DNS in PHP as well.

This problem is also solved already Richard... Tijnema
