Thank you for reaching out, and I completely understand your frustration. You are not alone with this problem — quite a few people with Asustor NAS systems have run into the same thing after Windows or ADM updates. The good news is that it’s usually down to how Windows is storing credentials or a mismatch in SMB settings, not a fault with your NAS hardware.
Here are the main things to try, step by step:
1. Clear old credentials in Windows
Go into Windows Control Panel → Credential Manager → Windows Credentials. Remove anything that relates to your NAS (entries showing the NAS name or IP). When you reconnect, Windows will ask for fresh login details.
2. Check SMB settings on the NAS
In ADM, under Services, make sure SMB is enabled. Set the lowest SMB version to 2 and the highest to 3. That avoids Windows trying to use the wrong version.
3. Verify your user account
In ADM, check the account you are using is not expired and has access rights to the shared folder. Sometimes the “account expired” message really does mean the user profile on the NAS needs re-enabling.
4. Map the drive by IP
In Windows File Explorer, instead of browsing the network, try mapping directly: \\[NAS-IP]\[sharename]. This avoids name resolution errors.
5. Restart both ends
After making changes, restart your Windows PC and the NAS. That clears out any cached sessions.
6. Optional reset
If none of the above work, you can reset the SMB service on the NAS and set up the shared folders fresh. Your data remains safe, but the SMB settings go back to default.
One extra point: many users create a dedicated user account and a shared folder just for their Windows PC connection. That way, even if the account gets confused by Windows updates, your main admin account stays untouched.
