TS-Agent Signature Issue

[sgoethals]

Hi,

I am setting up a  new Windows 2016 server that will host RDS.  I have installed TS-Agent (8.0.12).  No issues installing, however, the service won't start.

I am receiving  receiving the following:

The PAN TS Service failed to start for the following reason:

Windows cannot verify the Digital Signature for the file. A recent hardware or softrware change might have installed a file that is installed incorrectly or damaged or might be malicious software from an unknown source.

Has anyone else seen this or no of a work-around other than disabling signature checking on files.

Thanks for the help.

Hi @sgoethals 

You need to update the ts agent software to version 8.1.

Thank you so much. for the reply   Does it matter that I am runing PAN OS 8.0.10 at the moment?  What is the rule for different versions of TS Agent and the compatibility with the PAN OS?  I thought if I was on the 8.0 branch, I had to stay on the same for TS Agent.

I am planning to upgrade to a new version of PAN OS, but I wasn't planning on doing this until after I have my new RDS Server installed.

Actually right now I don't have the official recommendation in my mind ... but I use it the same way: TS Agent on 8.1 and firewalls on 8.0 ... works perfectly fine.

Thanks for the help.  Installing the latest agent as you indiciated fixes the issue.
