Question

how to visit every computer on the network and modify the hosts file in windows xp

Asked by: ITatES

Hello all,

We need to append a line to the hosts file for every user on our network. I have admin privileges, but don't know the first thing about windows scripting. Can someone point me in the right direction on this? I don't have the list of all the machine names, so I'd prefer a script that would discover all the machines on the network and do the update.

If you know a little .vbs you can utilize the Group Policy Logon to execute the .vbs script.  With a logon script, every time a user signs onto a computer in your domain the .vbs script will execute.  We utilize logon scripting for adding printers and network shares to each user's computer, along with ensuring each system has specific files on their computer.

Here is just one example I found on the net in a 5 second search.

Can I just ask for a minute WHY you need to do this?  Is there any reason why this can't work through an A or CNAME record in your internal DNS records - or is this for running when users are disconnected from your network?

The problem with any logon script or similar is that the user does not have rights to the hosts table by default unless they are local admins, which they generally won't be.

You could run a script as part of a startup script though through group policy if you have that, e.g.

@echo off
set hosts="%systemroot%\system32\drivers\etc\hosts"
set newip=192.168.199.10
set newname=server1
REM Check if it is already in there:
find /I "%newip%" < %hosts%
if errorlevel 1 echo %newip%  %newname%>>%hosts%

You can update all of the Workstations at once using this technique by running this Batch file if they are active. Place the two files in the root directory. Test it on one Workstaion first.

Create and run this from the file server. You will need 2 files. The first one is the .bat the second is a text file with a list of workstations that you need to add to in the same format.

C:\test is a folder on the File Server, place the updated file that you want copied in there. If the file exists on the Workstation it will be overwritten.

File 1 = copyto.bat

FOR /F " tokens=1 " %%i in (WS.txt) do copy C:\test\*.* "%%i\C$\C:\WINDOWS\system32\drivers\etc"

Put your files that you want copied into a folder EG: c:\test

File 2 = WS.txt

\\ws01.domain.local

\\ws02.domain.local

I agree with dragon-it for the most part. What I've done in the past is create a batch that runs through a Group Policy. The file that I create is an xcopy command that copies the hosts file from the server to each workstation like this:

xcopy "\\server1\c$\windows\system32\drivers\etc\hosts" "c:\windows\system32\drivers\etc\hosts" /r /e /y /h

Do you know how to use Group Policy to push this out?

There were several answers there worthy of answers IMO.

http:#25414382 RJCOLE
http:#25330215 rrjmin0
emiops contribution would not work in most environments as user permissions for login script would not allow updating of HOSTS.

are all valid techniques IMO.  Suggest 3-way split would be more appropriate.

thanks

Steve
