SOLUS 3 Agent Install - WMI Error

[Shuriken1]

Hi Everyone,

 

At a bit of a loss with this one.

 

One of our teachers' machines started throwing an "Invalid class" error when trying to run SIMS. I tried to reinstall SIMS via Solus 3 and got an error:

 

"Error occured obtaining data from the remote machine Check that WMI is enabled on the remote machine and any firewalls are configured to enable WMI traffic"

 

So, immediate course of action was to check Windows Firewall. We disable it for domain so I checked that it was disabled - it was. I then checked Network settings to make Windows considered the network to be a domain network so that it was applying the correct firewall policy - it was. I went into the advanced firewall properties and enabled all of the WMI related rules, in and out - no change. I also tried with the firewall service stopped - didn't connect at all, perhaps unsurprisingly.

 

I then tried to install SIMS via the S: drive, renamed the old folder etc - no change.

 

I then read about wmimgmt and fired that up, found similar invalid class errors on the General tab of the WMI Control properties. I followed a Technet article and seemed to get that fixed, it now reports the computer specs as it should. Hoorah!

 

Tried to reinstall the Solus 3 agent - didn't work. Tried running SIMS - it did work!

 

So I left it at that at the end of the day yesterday, come in this morning to find that the user can't log in, error "Incompatible Database". I go to check and sure enough, it's on a old version. Solus 3 still doesn't want to install but as far as I can tell WMI is ok. I've seen talk around the place of resetting the WMI repository but I've also read on Microsoft articles not to do that, so not keen on that idea.

 

Has any one got any ideas??

 

Thanks!

First question: is the agent showing as "online" in the solus3 infrastructure? if not, investigate firewalls, IP addresses, and check that DNS agrees that the IP is the correct one...

"Incompatible Database" usually means client and server are out of step, server on one version and client on a different one.

My first step might be to rename the sims.net folder on the client to "sims.netold" or similar and then redeploy to the affected workstation.

See if you end up with a new sims.net folder on the client. Copy a connect.ini in from the "old" folder and try again

When "solus3 still doesn't want to install" do you get a partially successful or failed status and what might the log file indicate?

Have you looked at permissions on the RSA Machine keys folder on the client PC?

Hi Neil,

 

The client is currently showing as Install Failed, I can't remember what it said before all of this started. I've checked the firewall, IPs and DNS, they all concur. I don't think the issue is here because it is getting an active failure message (i.e. WMI problem) rather than no response or not connecting. I've seen that problem with DNS and Solus, it's not doing the same thing as that.

 

Yes, they are on different versions. However, I can't update it because of the WMI problems when trying to deploy the Solus agent.

 

I have renamed the Sims folder and tried redploying, the agent won't install because of the WMI problems. I've tried installing SIMS straight from S:\ but that doesn't work either.

 

When Solus won't install I get the error message I stated in my original post, regarding WMI.

 

How would I go about checking the RSA Machine Keys permissions?

 

Thanks.

The folder you need to check is

C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys - everyone full control seems to work (!!)

Inside this folder is a file beginning 1d - We give that full control too

Remove the agent from Solus3 infrastructure and try to re add it
