服務器上安裝了SQL Server 2012，但Windows防火牆屏蔽了遠程訪問。在不關閉防火牆的情況下，需要手工打開所有SQL Server所使用的端口。微軟網站上發現個批處理，可以幫我們完成這個很蛋疼的重復勞動。
要打開的端口有1433、1434、4022、135、2383、2382、80、443、1434
@echo ========= SQL Server Ports ===================
@echo Enabling SQLServer default instance port 1433
netsh firewall set portopening TCP 1433 "SQLServer"
@echo Enabling Dedicated Admin Connection port 1434
netsh firewall set portopening TCP 1434 "SQL Admin Connection"
@echo Enabling conventional SQL Server Service Broker port 4022
netsh firewall set portopening TCP 4022 "SQL Service Broker"
@echo Enabling Transact-SQL Debugger/RPC port 135
netsh firewall set portopening TCP 135 "SQL Debugger/RPC"
@echo ========= Analysis Services Ports ==============
@echo Enabling SSAS Default Instance port 2383
netsh firewall set portopening TCP 2383 "Analysis Services"
@echo Enabling SQL Server Browser Service port 2382
netsh firewall set portopening TCP 2382 "SQL Browser"
@echo ========= Misc Applications ==============
@echo Enabling HTTP port 80
netsh firewall set portopening TCP 80 "HTTP"
@echo Enabling SSL port 443
netsh firewall set portopening TCP 443 "SSL"
@echo Enabling port for SQL Server Browser Service's 'Browse' Button
netsh firewall set portopening UDP 1434 "SQL Browser"
@echo Allowing multicast broadcast response on UDP (Browser Service Enumerations OK)
netsh firewall set multicastbroadcastresponse ENABLE
經測試，SQL Server 2012有效。（同樣適用於2008）
