SharePoint Event ID 6482: Could not find file 'C:WINDOWSsystem32driversetcHOSTS'.

  • Article

Typically I won't blog about an error until I've encountered it a few times.  Here's an exception to the rule.  smile_sniff  I had never come across this error and it caught me off guard during a recent installation of MOSS.  Usually when I've seen Event ID 6482, it's been because of the IIS lock (see previous post: SharePoint Exception Errors: Event ID 6398, Event ID 6482, Event ID 7076).  However, this was a different error description.

So why on earth is my hosts file missing?  After some online research, it appears that the host file is deleted/modified by the SharePoint timer service after you've made some changes to the WFE that is crawled by the search service.

Error Resolution:

To resolve this error, you have two things you have to do.

  1. Create a new hosts file at C:\Windows\system32\drivers\etc\

    The contents of a default hosts file typically looks like this:

     # Copyright (c) 1993-1999 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

127.0.0.1       localhost

  2. Once you've created the hosts file, you need to apply appropriate permissions for WSS_Admin_WPG to it.  If you don't, you are just going to encounter another error (This time a permission error:

    Access to the path 'C:\WINDOWS\system32\drivers\etc\HOSTS' is denied).
