Guest Luca Rossi Posted September 23, 2008 Posted September 23, 2008 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
Guest Meinolf Weber Posted September 23, 2008 Posted September 23, 2008 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.

Guest Luca Rossi Posted September 24, 2008 Posted September 24, 2008 Re: DNS Problem ?? Hi, i tried to configure scavenging, but it seems does not resovle the problem....

Guest Meinolf Weber Posted September 24, 2008 Posted September 24, 2008 Re: DNS Problem ?? Hello Luca, Do you have multiple entries in the forward lookup zone? A reverse one will not solve that problem.
