It's been set that way since the last time we had this issue. ??
First, make sure you are at C:\Windows\System32\drivers\etc
If you are, and there isn't a hosts file, you can create one. Make sure it's name is hosts and not hosts.txt
The basic contents of the file are:
# copyright (c) 1993-2009 microsoft corp.
#
# this is a sample hosts file used by microsoft tcp/ip for windows.
#
# this file contains the mappings of ip addresses to host names. each
# entry should be kept on an individual line. the ip address should
# be placed in the first column followed by the corresponding host name.
# the ip address and the host name should be separated by at least one
# space.
#
# additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# for example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within dns itself.
# 127.0.0.1 localhost
# ::1 localhost
You don't need to add those lines to the file, as they're only comments.
Open the file you created, add the line:
107.23.85.115 login.ultimaonline.com
And save it.
