We need to disable the DNS Client on our Win 2k boxes in
order to get our applications to work. What effect will
this have and what applications will be impacted?
Thanks

The only thing this affects is that it disables the DNS client resolver's
cache. It will just cause a fresh lookup each time there is a query and not
cache it. Kind of inefficient and adds traffic.

Curious, what results are you expecting by disabling this service? What app
would this affect? How? Maybe if you can shed some light, there might be an
alternative. IT could be something else causing whatever issues you are
referring to.

One thing, don't disable the DHCP client service (whether the machine is
using a static or DHCP IP). This will kill resolution completely and no one
will be able to logon or rseolve anything, locally on the network or the
Internet.

It does however make sense to disable this client on the actual DNS
server (if it is pointed at itself in it's own client settings) as there is
no
point in "caching twice" on the same machine.

It might also makes sense if you have high bandwidth/low usage
between clients and their DNS server and don't wish to deal with
the extra process or "stale caching" issues (at the client.)
 
Thanks for your input. On our IIS Web server we run a
custom CGI/ISAPI dll that will not load balance between
our Application Servers if the DNS Client is running. This
has forced us to stop the DNS client on the Web Server. I
do not know how the DNS Client interferes, but we do use
the HOSTS file to specify our Application Servers IP
addresses. We do not touch the DHCP client.
 
This will simply disable DNS client cache. For every resolution request, the client will have to contact the DNS server.

Thank you,
