ERROR_CTX_ACCOUNT_RESTRICTION
ERROR_CTX_ACCOUNT_RESTRICTION means the logon was rejected because of an account or security restriction. Possible causes include user-right assignments, explicit deny policies, NLA-related access requirements, Credential Guard, or account-specific restrictions.
What to check
- Determine whether the issue affects only one account or all users; a single-user failure usually points to permissions or account policy.
- Verify membership in the effective Remote Desktop Users group and the relevant allow/deny user rights.
- Review Security and TerminalServices events for the underlying logon status rather than changing firewall or port settings first.
