what could be causing SMTP transaction time to reach 16 second on one server and 4.5 seconds on another server on the same network

all I did was move MailEnable from one server to another.

original server is windows 2003 no websites running
second server is windows 2008 R2 with 4 websites

all MailEnable configuration is the same on both servers.
no firewall other than the router
Router settings is the same on both servers IP addresses.

Diagnostic Report time to complete is quick on the 2003 server and it take quite a long time to complete with error (The DNS took too long to execute. This may occur if you have hundreds of domains. Some diagnostic tests have been skipped.) on the 2008 server

Any suggestions will be greatly appreciated.
