Non-english locale casuses "Vendor Class not found" errors when using windows dhcp provider
Description
Good morning,
iam Setting up a new Foreman/Puppet infrastructure for provisioning VM's on VMware.
For this i need a DHCP Foreman-Proxy. I set up a new Forman-Proxy with following Details:
- Windows Server 2012 R2
- Foreman-Proxy stable Version 1.11.4
- netsh commands available and the DHCP Administrator Account is running the Foreman-Proxy-Service
The Foreman-Proxy is communicating with a DHCP Server based in Windows Server 2008.
The smart-Proxy.log said:

It seems it is a known Bug Comes if the DHCP Server is based on Windows Server 2008. I read this here (last Entry):
http://projects.theforeman.org/projects/foreman/wiki/ERF12-6899
There is also a Workaround for this, but it seems its for an old Smart-Proxy Version (ok - the post is three years old :) ) ...
I dont have the file dhcp.rb in path lib/proxy/dhcp.rb. This file is in my /module/dhcp path and the file is empty (just first "require 'dhcp/dhcp_plugin".
Did anyone know a Workaround for Smart-Proxy Version 1.11.4 ? ( i have this bug in 11.13 also .. :) ) - seems always been there and not Version specific.
Thanks for your Support.
Best Regards

Thanks for your fast reply. Iam sorry it still does not work.
I installed the whole VM with the Proxy Server 1.12.1 again. I still get the same error Message in the smart-proxy.log

Could you try executing 'netsh.exe -c dhcp server <your server ip here> show scope' from the command line?
I suspect the issue is with your dhcp server, but I'm not sure what could cause it. Is it possible that you have options from a removed vendor class assigned to one or more subnets?

Thanks for your reply. Yes its:
netsh.exe -c dhcp server x.x.x.x show scope ============================================================================== Bereichsadresse - Subnetzmaske - Status - Bereichsname - Kommentar ============================================================================== x.x.x.x - x.x.x.x -Aktiv -DHCP xxxx -xxx x.x.x.x - .x.x.x.x -xxx -xxx Gesamtanzahl der Bereiche = 2 Der Befehl wurde erfolgreich ausgeführt.
Sorry the server is in german language.
It said, the command is succed and the adresse details are right.
What do you meen with 'options from a removed vendor class assigned to one or more subnets' ? Is this something i can check or asking the DHCP-Team? Iam not the DHCP Administrator and my knowledge is limited here.
Thanks for your support

I didn't realise the shell was in German too. The version of ms dhcp provider you are using relies on parsing of netsh output to determine command status (among other things). Localised netsh messages result in errors, as the parser looks for english phrases.
You can switch the locale to one of the english ones and the error will go away. Alternatively, you can try using changes in https://github.com/theforeman/smart-proxy/pull/445, but they haven't been extensively tested yet.

Thanks for your reply. Its not so easy to change the current system language, so i have to create a new machine with the english .iso. That needs a little bit time, i will reply here when iam done.
