Office 365. All Windows 10. all PC's recently had the big win 10 feature update.
I have a FE & BE on PC 1 all wired LAN
I have FE on PC 2. wired LAN again.
With PC 1 FE running
When changing data on PC 2, after anything from few to 10 or so edits within the space of usually under a minute the data becomes corrupted.
Unrecognised format. A Repair recovers with all data OK.
It once did this very strange behaviour a year ago when I already had MalwareBytes installed & it upgraded to V.3. as soon as uninstalled it was fine.
Only does it if FE running on PC 1 & when PC2 FE running.
If FE not running PC2 works fine all day. So assume (99%) that network connection to the BE is probably fine.
PC1 will run fine all day
I have tried with various other PC's with the FE & BE in huge variety of different locations.
Decompiled FE
Fresh import of tables in the BE. Used backups before this started happening.
Driving me nuts!
Making harder to diagnose is the big Windows 10 updates, I do rather suspect some extra security is going on. I did switch Defender frewall & everything OFF briefly on PC2 but not the other yet.
Also had a power cut around the time of these problems but actually was not using during these few days so could be either.
Powered on/of any routers/modems switches etc.
LAN Speed test seem smooth 200Mbps+ which is normal for me.
Trouble is also a few days before I was testing malware AV sfotware again & installed Malwarebytes, all actually seemed OK then but I scanned & then removed, even used the remover tool. I also tried Kaspersky and again removed & used there tool. Decided to simply keep Windows defender.
I have test on PC's that have never had these installed FE & BE combinations so sure can't be these.
Running out of ideas & things to try.
This may be really dumb but in many,many years never needed and always worked without fail, The BE on PC1 is not in my trusted locations on PC2. Should it be? I can access/read & change a few things even now so seems odd. Going to test now but means allow trusted location on my network, not reccommed. I have always had full access to my network without this so confused.
