Mac cannot access SMB share after password change

Scenario

A Mac user changes their directory password and then cannot access the office SMB share.

Recommended Resolution Path

1. Delete stale Keychain items for the file server.
2. Reconnect using the updated username format expected by the NAS or AD integration.
3. Check SMB dialect compatibility and signing requirements if only Macs are affected.
4. Verify the share permissions and lockout state from the server side.

Technician Notes

Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
