@PDQ i love your employers, drinking at work are you even allowed to smoke? Do you have jobs to offer?.. just joking

If you “watched” the video, they are looking for a sys admin. So yes they do.

Troye Johnson

@PDQ & @george1421 Hi guys I have a question how did you guys pass the PDQ background user credentials from fog. Did you change the fog service user to match that user?

george1421

@Troye-Johnson I think that part needs to be answered by the PDQ guys. I can tell you by default the FOG client runs as the SYSTEM account.

I could see its possible that if the fog service account was changed to run as a domain user account and that domain user account had local admin rights (on the target computer) as well as rights to reach out to the PDQ Deploy server, and listed as a console user in PDQ Deploy that would work and still keep everything secure and functional.

Troye Johnson

@george1421 I did try this and it worked, but also in the webcast I heard them say “did you remove your password from the script” my boss thinks they have a way to run the script as any user from from the fog console. @PDQ can you explain how that process works?

Joe Schmitt

@george1421 the FOG client should never be set to run a domain user. The client’s security model relies on the assumption of running as SYSTEM/root. In addition if the client runs a domain user then it will not be able to rename, join, or leave a domain. Since when the client needs to temporary leave remove a machine from the domain, the client would loose all privileges.

Ultimately the client may or may not work as non-SYSTEM users, but its not something we recommend or will officially support.

Sounds great how do you guys want to manage fog images in a better way as it is? Little details please?
FYI i am a paying PDQ Deploy Customer Lovely tool.

@george1421 Actually reminded me to renew the domain name on that one before I lost it! God I need to post more updates.

We’re still using FOG and PDQ to image out our 1:1 fleet of computers, as well as having it tied into our server deployments automated via Ansible onto our Proxmox KVM boxes. It’s working fantastically.

The next thing I’m working on (shoot for the moon, right?) is to use FOG to host Snapins and make them accessible outside of the LAN, that’ll then pull down some powershell to grab files via HTTPS from our web cluster to do remote installations if needed. I’ve got a proof of concept working, but I’m a 1 man shop and haven’t had time to do much more on it. But if it works, I’ll effectively be able to push installs both on and offsite, without having to use DirectAccess as the tie back. The powershell has some if’s in there to see if they’re on the LAN, which will then tell it to grab PDQ’s packages, but if they’re off, it’ll grab them from the HTTPS repository and fire off msiexec on them manually.

It’s poor mans SCCM!

bmorris

@Troye-Johnson Did you ever get an answer to your question? I am running into the exact same problem. Since the service runs as SYSTEM, it doesn’t have permissions to even remote powershell to our PDQ server.

Troye Johnson

@bmorris Yes I we created a domain user added that users under the “pdq deploy> Preferences>Credentials” to allow it access to deploy apps and then added those credentials into the PDQdeploy script by powershell. Here is my script I encrypted the password for best practices.


<#

Im not sure if it works with server mode of PDQ deploy that was just released yet though I have not tested it. If you get a chance to please let me know.

bmorris

@Troye-Johnson Thank you very much for this. I will report back if this works for server mode of PDQ Deploy.

Troye Johnson

@bmorris Please remember to add this registry setting based on PDQ recommendations

Additionally, you’ll need to add an entry into the registry on the PDQ Deploy machine in order to tell the background service to use TCP/IP:

Location: HKLM\Software\Admin Arsenal\PDQ Deploy\
Type: DWORD Name: ServicePort Value: <port number>

The value needs to be a port number that is allowed within your network.

or find it here https://www.adminarsenal.com/webcast-bonus-content/

bmorris

@Troye-Johnson I forgot to ask, which I am sure I will find out anyway through testing, but is your FOG Service running as the default SYSTEM account on the client using this script? Since you are specifying creds in the script, this doesn’t matter now, I assume.

bmorris

@Troye-Johnson Thanks for this. PDQ actually provided me with an update that fixes this issue on v13. No need for the registry setting change. The update put us on v13.2.0.0.

An update on this. I got it working, and it worked fantastically. Presents a webpage, user pics what apps they want, and it makes an exe that fires off to tell PDQ to install it.

HOWEVER

In discussions with PDQ, I was told that it’s a violation of the EULA, as each user who is ‘interacting’ with pdq, in this case telling it to fire off, would need to be licensed. It doesn’t apply as much in this instance, so you’re the one firing it off each time in the image, but something to consider if you have multiple techs who do the imaging, etc.

bmorris

@Bob-Henderson Interesting. Probably a good thing each of our techs are licensed for PDQ Deploy then! Good work though.

Troye Johnson

@bmorris Yes no need to change the fog user on the service.

bmorris

@Troye-Johnson Excellent. I will let you know what I find out! Thanks again.

Troye Johnson

For the licensing aspect you can create different power-shell scripts for each of your techs so that you can keep an audit of who ran what when applications are being deployed. This way not only will you stay in compliance with the eula but you also have an audit if something happens.
