why telnet from PC to Solaris x86 is extremely slow?

I got the following info from this forum, in regards to configuring my
Solaris x86 to link to the Net:

# echo > /etc/defaultrouter
# route add default
# echo nameserver >> /etc/resolv.conf
# cp /etc/nsswitch.dns /etc/nsswitch.conf

So I did the above steps, reboot the Solaris, and my Solaris system
can link to the Net fine afterwards. But ever since it had Net access, another problem is created.

Whenever I telnet using a command line from a Windows XP computer, it
takes a long time to telnet to this Solaris system. Before, I would see the Solaris login prompt for telnet in a few seconds. Now, it's about 1 minute. Plus, if I try to use an xterminal software from that PC to link to the Solaris x86, it hangs.

So after I undo all the 4 commands above, reboot the Solaris computer,
all these problems disappear. I can telnet from my Windows PC to this Solaris system very quickly. However, I no longer have Internet
access from my Solaris.
Anyone knows how I can fix this problem? Thanks.

this is because the telnetd is doing a reverse lookup of the ip of your PC.

add your PC's ip address to your hosts file.

or setup your resolv.conf to point to DNS servers that know about your PC.
