Re: IE6 and slow domain resolution

Hi FT;

Another thing to try is to locate your HOSTS file (no extension). It will be
in C:\WINDOWS\SYSTEM32\DRIVERS\ETC . The Hosts file contains the mappings
of IP addresses to host names. This file is loaded into memory at startup,
then Windows checks the Hosts file before it queries any DNS servers, which
enables it to override addresses in the DNS. This prevents access to the
listed sites by redirecting any connection attempts back to the local machine.

Add .txt to the file name and open it up. check the entries and see if it is
blocking your DNS server, or if it is extensively long (could cause slow dns
I actually removed everything and left the HOSTS file with the .txt
extension and had no problems.
