I have four depot sites that communicate with our HQ using a 501 PIX at each site and a 506e at HQ. We not have any DNS problems with the PCs at these locations. We are running DHCP using a Motorola WS2000 at each site. The problem is with the Symbol handhelds running Windows CE. They Tcom with a server at HQ. They work fine with the IP address of the server in the tcom settings. When we try to use a DNS setting in them they cannot resolve the name.
All of our other sites communicate over a frame relay network using the same WS2000, handhelds, and settings. Their HHs do not have problems tcomming using DNS. The only difference between the sites is these use a PIX.

I have tried removing the fixup protocol dns maximum-length 512 command from the PIX configs and they still cannot resolve the DNS name. I have spoken with Symbol and asked if they do anything special with DNS requests and they said no. Any ideas?
 
Found the problem. The Handhelds are not members of our domain. When querying DNS they would not add the domain name to the name it was querying for. For example the server name is abc123. When the HH would try to resolve in DNS it would send the name is abc123 which is not a FQDN. I added the domain name to the DHCP scope on the WS2000 WAP and they were able to resolve the name correctly.
