This is the resource I use to install the jenkins agent service:
exec { 'install-service':
command => "sc.exe create ${jenkins::servicename} start= demand
binpath= ${jenkins::serviceexe} displayname= ${jenkins::servicename}",
path => "${path}",
logoutput => true,
unless=> "sc.exe query ${jenkins::servicename}",
}
Note that `sc.exe query ` will return zero if the service
exists, preventing the service from being reinstalled.

It's not necessary to wrap the sc.exe command in cmd.exe. That sort of
thing is only necessary when trying to execute built-ins like echo, mkdir,
etc. So for example, to echo, you have to do: cmd.exe /c echo 'foo'

Notice in my exec resource above, I set path => ${path} and then executed
'sc.exe'. This tells the exec resource to use the `path` fact, so that I
don't have to specify where `sc.exe` lives. For example, if SYSTEMDRIVE is
'D:'

So error 123 is "The filename, directory name, ... is incorrect". That's
because cmd.exe is trying to execute "C:\Windows\System32\sc.exe query
nsc-devops", instead of executing C:\Windows\System32\sc.exe with the
arguments 'query' and 'nsc-devops'

I think you need to use something other than 'create' to modify the
description for a service that already exists.

Just do `c:\windows\system32\sc.exe query nsc-devops`, or just `sc.exe
query nsc-devops` with the path trick above. If the service exists, it will
return exit code 0, otherwise non-zero.
