Windows 10: After reinstalling Windows 11 cannot connect to NAS from more than 1 account

This is very odd. A few days ago, I had to reinstall Windows 11 on my laptop. I downloaded the Media Creation Tool and performed a clean installation, a procedure I have execute hundreds of times. The installation required a Microsoft account, which I entered. After completing it and making my home network a private network, my NAS turned up in Explorer.However, for the first time in my life, after double clicking it, it said can't find it showing error code 0x8...... following later. It was accessible through a browser, but not in the network neighbourhood, not even entering \\NAS in a comm

File Transfer Speed from Windows 11 to Synology NAS is VERY SLOW vs. Windows 10

I have a new Windows 11 PC and I'm noticing that the file sharing to my Synology NAS is very slow vs when I transferred files from my older Windows 10 PC.

File Transfer Speeds:

• Windows 11 to NAS (DS1520+) = 11.5 MB/s
  
• Windows 11 to Windows 10 = 112 MB/s (much faster)
  
• File size = 30GB
  

Note:

• Windows PCs and NAS are all Ethernet connected on 1GB home network.
  
• Running: Windows 11 Pro 23H2
  
• Running: DSM 7.2.1-69057 Update 5
  

Any suggestions on how to speed this up would be greatly appreciated. Thanks.
