Solucionar problemas de conectividade do SQL com o Microsoft Entra Connect
Este artigo explica como solucionar problemas de conectividade entre o Microsoft Entra Connect e o SQL Server.
A captura de tela a seguir mostra um erro típico, se o SQL Server não puder ser encontrado.
Etapas para solucionar problemas
Abra uma janela do PowerShell e importe o módulo ADSyncTools do PowerShell
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
Import-module -Name "C:\Program Files\Microsoft Azure Active Directory Connect\Tools\AdSyncTools"
Observação
O Módulo de Instalação requer a atualização para PowerShell 5.0 (WMF 5.0) ou posterior;
Ou instale a Versão prévia do módulo PackageManagement do PowerShell – de março de 2016 para o PowerShell 3.0/4.0
- Mostrar todos os comandos:
Get-Command -Module AdSyncTools - Execute a função do PowerShell:
Connect-ADSyncDatabasecom os seguintes parâmetros- Servidor. O nome do SQL Server.
- Instância. (Opcional) O nome da Instância do SQL Server e, opcionalmente, número de Porta que você deseja usar. Não especifique esse parâmetro para usar a instância padrão.
- UserName. (Opcional) A conta de usuário para se conectar. Se deixado em branco, o usuário conectado no momento será usado. Se você estiver se conectando a um SQL Server remoto, essa deverá ser a conta de serviço personalizada que você criou para a Conectividade SQL do Microsoft Entra Connect. O Microsoft Entra Connect usa a conta de serviço do Microsoft Entra Connect Sync para autenticar em um SQL Server remoto.
- Senha. (Opcional) Senha para o UserName fornecido.
Essa função do PowerShell tentará se associar ao SQL Server e à Instância especificados usando as credenciais passadas OU usar as credenciais do usuário atual. Se o SQL Server não puder ser encontrado, o script tentará se conectar ao serviço SQL Browser para determinar as portas e os protocolos habilitados.
Exemplo ao usar apenas um nome de Servidor:
PS C:\Program Files\Microsoft Azure Active Directory Connect\Tools> import-module .\AdSyncTools.psm1
PS C:\Program Files\Microsoft Azure Active Directory Connect\Tools> Connect-AdSyncDatabase -Server SQL1

WHAT TO TRY NEXT:
Each SQL instance must be bound to an explicit static TCP port and paired with an inbound firewall rule on SQL1 to allow connection. Enable the SQL Se
rver Browser service temporarily on the SQL server and run this cmdLet again to further troubleshoot the issue. Alternatively use the SQL Server Configur
ation Manager on SQL1 to verify the instance name and TCP/IP port assignment manually.
You must specify both the instance name and the port to connect when the SQL Server Browser service is not running. An inbound firewall rule on SQL1 is required for the associated port.
Example: 'MySQLInstance,1234' where 1234 has a matching firewall rule.

WHAT TO TRY NEXT:
Each SQL instance must be bound to an explicit static TCP port and paired with an
inbound firewall rule on SQL1 to allow connection. Review the TcpStatus field
for each instance and take corrective action.
