Secd DNS timeout server

Hi All, 

I have errors on my connection timeouts.

 ERROR secd.dns.server.timed.out: DNS server XX.XX.XXX.XXX did no t respond to vserver = XXXXXXX  within timeout interval.

 ERROR secd.conn.auth.failure: Vserver could not ma ke a connection over the network to server (ip XXX.XX.X.XXX, port 389) via interface XX rror: Operation timed out 

Thanks,

Nayab
