CSS is Microsoft Paid support.

if I remember right sms_fsp is the Fallback status point and if you are getting lots of hit on it then you like have an issue with your environment. Maybe a cert issue. Look FSP reports, check your certs. Re-reading this thread, IMO you have a certificate / PKI issue. PKI is a huge pain in the a.. ; hence why I never recommend it. It might be time to contact CSS directly for support.

You need to open one of the IIS logs and look at what is going on. From there you can tell if MP traffic or Inventory traffic or what is making your logs grow.

This query will only find x86 version of the software. You will need to update the collection to gather x64 version too. https://www.enhansoft.com/blog/combining-two-wql-queries-in-one-collection

it sounds like your site is not healthy. Test you MP is it working correctly? https://www.enhansoft.com/blog/how-to-test-your-mp-to-confirm-if-it-is-healthy if not remove it and add it back again.

What does your collection query look like?

Is it set for a fixed time or a simple time for the Hardware inventory? BTW, I recommend this be set up for daily. https://www.enhansoft.com/blog/configuration-manager-inventory-cycle-recommendations

What is your hardware inventory schedule? Why do you care who was the last user login to the computer?

if you review the status messages it will give you suggestions for each error have you done these suggestions?

Now that I'm back in the office and can look at this. Both queries will return the same results. Both queries will use the last login user when your Hardware inventory last occurred. If no one was login when HW inventory occurred, it would be null.

This query will only show you computers who last logon user was X.

What does your query look like ?

Without your query, there isn't a lot anyone can do to help you.

There is no where near enough details to give you any useful insight. You have not answered any of my questions either. Again there is no product call SCCM 2016. You must be looking at CMCB.

Why do you need a separate management console for servers and desktops? Why can't you have one console and use Role Based administration? Why is wrong with you exist environment? Honestly no one can answer this without knowing a lot more details. As such it might be worth hiring a consultant to help out. Note that there is no product called SCCM 2016. Therefor you must have CMCB

There is no such things an a MP proxy. Your only solution is to allow clients at your secondary site to access the MP at the primary site. All of this is covered within the documentation for CMCB.

Remember just because a SU was applied doesn't mean it is installed or still installed or will install again. There isn't a report that will show you just there are report that will show what is installed and not installed for a computer.

QFE, does not listed all SU so understand that it will/can be missing some. Since CM applied the SU it shouldn't be behind on what was installed more than 15 minutes (default setting). I'm not following you as to how this will all be used together.

Have you looked at the built-in reports?

So what does you query look like now?

Advanced Installer is great and is it even cheaper than PACE!

You should look at Advanced installer, it is prices right.

You can't merge them. At best you can migrate their app and package to the new CMCB site. No you don't need to extend the schema again. There are no attribute chagnes in CMCB.

if all you do is update the content, then it will NOT affect these already installed.
