Hi to all, i've a problem on my domain (Win2003 Server and XP clients):

Often, if i ping a host it does not responds, but the IP that returns
probably was previously and now no more working. Assumed that i know the
correct IP of that host, if i ping the address with -a flag, it returns the
correct hostname....
Example:

1) Ping p-crespi.alerva.local [192.168.15.115] con 32 byte di dati: --->
does not respond

2) Ping 192.168.15.83 -a --> It works and resolve P-CRESPIalerva.local....

Is it a DNS problem or a DHCP problem ?

Thanks to everybody in advance
Bye
Luca
 
Re: DNS Problem ??

Hello Luca,

Seems that in your DNS server, some old records listed with previous ip addresses
fro computers. Check the forward/revers lookupzones. To prevent this you
can either use scavenging or configure the DNS dynamic updates registration
in DHCP.

Re: DNS Problem ??

Hello Luca,

Do you have multiple entries in the forward lookup zone? A reverse one will
not solve that problem.
