Forward DNS problem

For some reasons, few of our windows XP workstation computers vanished from the Forward lookup zones but still show on the Reverse lookup zones. We have to manually enter them on the forward lookup zones.
Any ideas what could cause this problem. The event viewer on the workstations and server don't report anything.

Hi tshi5791,

are you clients pointing only towards your DNS server for DNS

yes, they all use DHCP and the DHCP only has one DNS server that is the DC.

Is automatic scavaging setup?  right click at the server level and go to properties.  Look under advanced.

Yes, but this seems to affect only few workstations.

If using DHCP, right clicking on the scope in the DHCP console and choosing properties. Under the DNS tab try checking:
-Enable DNS dynamic updates according to the settings below
-always dynamically update DNS A and PTR records
-discard A and PTR records when lease is disabled

If using static (not a bad idea even with DHCP), make sure network cards, under advanced TCP/IP properties, on the DNS tab, have "Register this connections addresses in DNS" checked. Make sure this is checked on the problematic workstations for sure.

uncheck automatic scavanging and things seem to be working fine.
