Hello,
I am having hard time doing this and i’m not good when it comes to scripting, I have seen/copied some tips on this forum but I am getting error in bigfix action script saying unknown command. does anyone have a working script for changing dns that I can test or use? Thanks appreciate any help.
Can you post what you’ve got so far and we can help you from there?
I have tried SystemAdmin’s post, but I get unknown command in the actionscript on the registry part of the task in bigfix.

Looks kinda like the line feeds got butchered

runhidden dns2.batThanks Sir. I will try your script.
If it is possible to do on the command line or with a script, then it is generally possible to do it with BigFix.
Can you provide the original link to where you found this script?
It is definitely missing some end of line characters which would cause issues. It seems like it didn’t copy correctly.
Hello Sir ( @jgstew ), Sorry for the late reply, Happy holidays I got the script from this link Legacy Communities - IBM TechXchange Community
Sir ( @strawgate ), I followed the script that you gave to me, I didn’t got an unknown command prompt but I got an error status when I deployed it. Is there something missing with the way I deployed it?
Thanks
Here is the script in the new forum: How to deploy OpenDNS or How to change DNS settings on workstations
Also, I wouldn’t recommend blindly using that script without validating what it does and how it does it on the command line before trying to deploy it through BigFix. It makes some assumptions about the names of the networks instead of querying them dynamically and it tries to set them on a bunch of differently named networks even if they don’t exist. In general it might not do what you need depending on your situation.
What is the goal you are trying to achieve?
my goal is to deploy/change dns ip addresses to workstations, actually the one that I screenshot was from my lab test account. I have read that there is a possibility that bigfix can do it, instead of changing it manually per workstations.
It definitely can do it, it is just a matter of figuring out what the correct commands are to make the changes needed.
The script you referenced seemed to be for setting DNS to OpenDNS specifically.
Which OSes are you trying to do this for? Windows 7 or later?
I haven’t really ever done this before, so I’d look for microsoft documentation on how to do this for the targeted OS. I’d also use relevance to dynamically target only the connections that actually exist on the target computer instead of the blunt force approach in the existing script.
For OS Windows 7 or later, but I’m currently testing it first for Windows 7. I think the relevance is quiet correct but something in the command line seems not working, I’ll just try to figure it out for the moment. Thanks for sharing your ideas on this matter Sir jgstew. Happy New Year!
It may be important to make a distinction between computers configured statically normally, those configured statically that are a special case, and those using DHCP.
This should be the name of the network that needs changed: ( Examples are from Win10 )
Q: names of connections of networks
A: Ethernet
T: 52.708 ms
.
Q: addresses of dns servers of networks
A: 192.168.1.1
T: 19.102 ms
Thanks, to answer your question:
replace another DNS
yes to some workstation and no to others
yes
Your answers are a bit contradictory, but it sounds like you want to put a new set of DNS servers at the top of the list of currently configured DNS servers for endpoints, but retain the current set of DNS servers at the bottom of the list, instead of just entirely replacing the DNS servers configured.
This is definitely more complicated than the example script will do, though possible.
