In http://www.Macfixit.com this problem was this is what someone said and their solution:
> Lately I've been noticing problems with my PowerBook experiencing odd moments > of lag when I use it on my home network. This slowdown doesn't occur at the > office, however. I checked /var/log/system.log to see if any problems were > being reported and saw lots of DNS error reports from lookupd. I searched the > web and found a couple of threads on the subject. One of which was at MaxFixIt > and mentioned possible problems with obtaining DNS server assignments via > DHCP. I verified that the servers assigned by DHCP were correct and even tried > manually setting this but the problem didn't go away. This led me to find the > actual problem. > > At home, my network traffic passes through a Linksys router, which handles > Network Address Translation (NAT) allowing all of my computers to share a > single connection. The problem is, OS X doesn't handle DNS queries through the > Linksys' NAT connection very well. The solution was to manually tell OS X that > the Linksys itself is the DNS server. > > To do this, go to the Network System Preferences pane. In the box titled > 'Domain Name Servers, enter the IP address of the Linksys router (most likely > 192.168.1.1). This will have the workstation use the Linksys as a DNS relay > instead of trying to contact the actual DNS server directly, which seems to > confuse lookupd when it goes through the NAT process. > > > The Linksys will then handle forwarding the DNS requests on its own and > respond to the Mac OS X system as if it were an actual DNS server itself. If > you have a DNS server on the local network (as we do at the office) this isn't > a problem because you probably have the DHCP server set to assign that local > DNS server to all client machines so the Mac OS X systems don't have to deal > with handling potentially screwy replies through a NAT system. > > Sherman Wilcox1/3/02 2:42 PM said: > >> This isn't an Entourage question, sorry -- but it affects Entourage.
