My network consists of 2 desktop Lenovos, with A being quite a bit older than B. Both are running Win10Pro, with A (formerly a Win7 machine) running 1903 and B runninng 1909. Until today, both were regularly accessing a mapped MyBookLive (MBL) NAS for file storage. I also have a newer MyCloud NAS that A has been using to back up the MBL. All of this is on a wired network and was working fine.
Today I tried to get B to recognize the MyCloud NAS, but B couldn’t find it. I tried without success to determine what was different between A and B. I then went Googling for possible solutions. On a Microsoft webpage I found the suggestion that Win10 had disablied SMBv1, and older NASes likely couldn’t live without it. Odd, since it was my newer WD NAS that wasn’t working with it, but I tried what was suggested:
Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol
That didn’t help, so I disabled it with:
Disable-WindowsOptionalFeature -Online -FeatureName smb1protocol
I then discovered that A and B were both now unable to find the MBL. I broke something, and I don’t know what. I re-enabled SMBv1 on both machines, and A can now reach the MBL, but with long delays, while B times out more often than not when trying to reach the MBL.
Do you have any suggestion for what I might have broken? I’m overdue to back up the MBL to the MyCloud, but I suspect backups will fail with these timeouts.
Thanks for any help!
