I have made an account for user 'backup' on each computer to allow backup of remote files from a central PC..

Don't use multiple LANs. Please Lucifer, Enlighten me how to test the behavior of rogue equipment (like 'calling home') without such a setup? And don't start about port mirroring on switches, I don't like to pass data before it has been analyzed. Arie |

The trick is in the manual route command, I used that before becoming lazy, using GUIs, and completely forgot it can also set a metric: route ADD 157.0.0.0 MASK 255.0.0.0 157.55.80.1 METRIC 3 IF 2 ^^^^^^^^ I'll start testing that hoping SMB really checks for that metric!

My solution was to download+install v1903.
Paul replied:
M$'s updates are a nightmare. I find most of the time, using a Catalog.Update.Microsoft.COM version of a KBxxxxxxx update (a .MSU file), most always clears a logjam. The situation is "manageable", but hardly a reason for an Oscar trophy. Now the people who leave their failed updates in a big pile, and you find two years worth of failures... I like to update my Windows 10 PC every 6 months or so. For 6 months, I couldn't update it ( v1803 ). My solution was to download+install v1903 ( C:\Windows10Upgrade\Windows10UpgraderApp.EXE ); after which, I had to rename the "Documents" folder back to "Sys", as that's what I always call it. Also, I had to re-take ownership of "DefaultMediaCost" -Manually-, [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\DefaultMediaCost] Re-Merge-In my settings ( Jeff-Relf.Me/Win10.REG.TXT ), check for updates, ReBoot, and -Manually- change .JPG and .PNG file associations using "Open With". Also, I had to re-format all of my File-Explorer folders, so they look the way I want. Likely, I'm doing something(s) wrong. |
