Some Notes on the Machines

This tool, is how to make sure your firewall is set up correctly to allow StorageCraft cloud services:

There are QoS settings which can be made within Windows! They work with desktop and server OSes, to set priorities on either network traffic of specific binaries, or by port and type. If you see programs or services stopping unexpectedly, stuttering, et cetera, this is good to try. Here is a basic guide in PDF:

http://notes.ponderworthy.com/file_download/12/Basic_PC_QoS.pdf

The steps:

1. Load up MMC.EXE.
2. Open the File menu
3. Choose Add/Remove Snap-In.
4. Click Group Policy Object Editor on the left.
5. Click Add.
6. Click Finish.
7. Click OK.
8. Open up Local Computer Policy, Computer Configuration, Windows Settings, Policy-based QoS. You’ll see the following, with the policy list being blank if you haven’t done this yet.

9. Right-click on Policy-based QoS, and choose Create new policy. Set a name, and then set the DSCP value:

The DSCP value is the priority level for the policy. The range is zero through 63. Here is one common DSCP value set:

0 …………………..General Traffic, unprioritized
10 …………………Backups, file transfers, non-business applications
25 …………………Mission-critical data, including SQL, video streaming
34 …………………Video conferencing
46 …………………VoIP

Another set, not quite the same, standardized within the WMM wifi standard:

8-23 ………………Background (BK)
24-31, 0-7 ………Best effort (BE)
32-47 …………….Video (VI)
48-63 …………….Voice (VO)

The above are far from a coherent standard everywhere; one can even find lists which peak at 30. For my needs within PCs, I have been setting my critical apps at 31, important apps at 24, and not bothering with anything else. And it is needful to be conservative. If you QoS some things too high, Windows won’t be able to do background things which keep it running…like, say, the Windows desktop ☺

10. At this point you need to decide on the type of QoS policy you are creating. You create them to work by TCP/UDP port for all applications, for application binaries of specific names, and for HTTP/HTTPS URLs.

11. You may now choose IP address(es) to which the policy applies.

12. And then TCP and/or UDP ports to which the policy applies. Default is TCP only.

And now you’re done with that policy, and you can create as many more as desired.

If you get PsTools, and do this:

psexec -i -s CMD.exe

you’ll get another CMD box, where the username is SYSTEM, that is to say, the hostname of the machine with a dollar sign on the right end. If the machine is on a domain, it is DOMAIN\hostname$, have not tested it on a non-domain machine yet.

One software installer recently, required that the folder containing its installer package be TAKEOWNed and ICACLSed, as that system user, before it would run to completion, it must have some odd permissions bug in it.

There are likely to be quite a few circumstances in which this special CMD can be useful.

These steps change quite often, fair warning!

Steps below are as of 2021-01-04. Please note this has to be done in Internet Explorer or Edge.

First, set permissions.

1. Browse to protection.office.com/homepage , log in as tenant administrator
2. Click eDiscovery Manager.
3. Open eDiscovery Administrator, and add your current admin user.

It takes one hour (as of Microsoft support 2021-01-04) for the permissions to take effect. Used to be up to 24. Afterwards, perform the export.

4. Browse to protection.office.com/homepage , log in as tenant administrator
5. In left pane, click Search, then click Content Search
6. Click New Search
7. At bottom, item Specific locations, click Modify
8. At top left, Exchange email, click “Choose users, groups, or teams”
9. Click “Choose users, groups, or teams” in the new window
10. Enter mailbox email address, wait until the search results come
11. Check the mailbox, and click Choose, then Done
12. Click Save
13. Click Save & run
14. Name the query (and PST), click Save. The query will run. Don’t continue until it’s done. It will say “Status: completed” at the lower left.
15. Click on the word “More” at the top, just to the left of the word “Sort”.
16. Click on “Export results”. Choose options appropriately. Click Export.
17. Click on “Exports” above that area, to the right of “Searches”. If the export does not appear, click on Refresh.
18. Click on the export item.
19. Click on “Download results”. A download applet will start, requiring an export key which can be copied from the browser. Paste it in, choose your download destination, and go! It can take a very long time to start, there is a long preparation phase.

To see if there is cleanup to be done:

DISM /Online /Cleanup-Image /AnalyzeComponentStore

To remove obsolete and unused system files:

DISM /Online /Cleanup-Image /StartComponentCleanup

To remove obsolete and unused system files and also service pack uninstallation files:

dism /online /Cleanup-Image /SPSuperseded

To remove obsolete and unused system files and everything prior, making it impossible to reverse any patches:

dism /online /Cleanup-Image /StartComponentCleanup /ResetBase

This:

wmic product where "name like 'Java%%'" call uninstall /nointeractive

appears to work very well for products whose names start with “Java” which are installed in Windows standard fashion.

If MMC for any Windows administrative tool gets stuck, delete everything here:

C:\Users\USERNAME\AppData\Roaming\Microsoft\MMC

If (when) Outlook bogs down, especially when dealing with multiple accounts in a single profile, disable the existing Send/Receive Group and create a new one, make sure all accounts are included, then set that one to be checked every 30 minutes.
