## Error message
```text
Account restrictions are preventing this user from signing in.
```

## TL;DR
Something on the account object itself is blocking the logon, not the password. Open the user in Active Directory Users and Computers, check the Account tab for expired passwords, logon-hour limits, and the disabled flag, then fix whichever restriction is set. The user signs in on the next attempt.

## Steps
1. In Active Directory Users and Computers, open the user's properties and look at the Account tab.
   Expected: You see the account expiry, logon hours, and disabled status.
2. Check whether the password expired, logon hours exclude the current time, or the account expired date has passed.
   Expected: One of these restrictions is visibly set, or the account shows disabled.
3. Clear the offending restriction: reset the password, widen logon hours, extend the account expiry, or re-enable the account per your change process.
   Expected: The restriction is removed and the account state shows normal.
4. Ask the user to sign in again.
   Expected: Sign-in succeeds.

## When to use
- The exact message appears instead of a bad-password message
- Contractors or temporary staff suddenly cannot sign in on a specific date
- A user reports they can sign in at some hours but not others

## When not to use
- The message says the trust relationship failed (different error entirely)
- The workstation has no network path to a domain controller (check connectivity first)
- The password is genuinely expired and the user only needs a reset link

## Why this happens
Windows evaluates account restrictions before it ever validates the password. Expired accounts, logon-hour windows, and the disabled flag all surface this same generic message, which is why checking the Account tab first saves a password-reset wild-goose chase.

## Edge cases
- Password-expired users may need the password change forced at next logon rather than a silent reset.
- Service accounts with expired passwords show this message in application logs, not on a sign-in screen.
