dns problem
i have 2 machines one desktop and one laptop in my house.desktop has
two network cards.one connected to internet and other to my local
192.168.100.0 intranet(intranet of just 2 machines using a small hub
hehehe).the laptop is also connected to my 192 intranet.now i want to
access internet from laptop.One solution that i did is to run a proxy
server in desktop and in IE of laptop give the address of the
proxy.this works fine when i use IE but this is useless in case i want
to connect to a an outlook exchange server which has no setting for
defining the proxy server(as in yahoo there is such a setting for
proxy).Can we do the same in microsoft outlook.It works fine on
desktop but if i wanna use it in laptop its a mess.the other solution
which is as follows:
1.Run a DNS server in desktop.Default settings.
2.Give the address of this server in my network settings in laptop.
3.Now when i tried to ping some site.it resolves IP address but it
gives request timed out.this is applicable to all sites.
check this output

F:\Documents and Settings\Administrator>ping -t yahoogroups.com
