當AutoCAD 2019 執行時發現等待很久
※請確認在斷網時無此問題，再使用下列方案
主要原因是程式啟動時，會連線到169.254.169.254(這是Amazons EC2服務器)
解決方案：
在本地防火牆添加限制連到169.254.169.254的規則，就可以解決了

1. 以系統管理員身分執行 CMD
2. 執行 netsh int ip sh int 然後按下"Enter"鍵
Identify your loopback Idx (first column).
Exec netsh int ip add addr /32 st=ac sk=tr and press "Enter". In my case, with IDX=1 I exec: netsh int ip add addr 1 169.254.169.254/32 st=ac sk=tr.
To delete the rule use the command: exec netsh int ip delete addr .
st=ac stands for store = active. This means the IP address you are adding to the loopback adapter will automatically disappear upon the next boot of the system. If you need to keep the changes, then change the argument to st=persistent.
sk=tr stands for skipassource = true. The man page reads: “skipassource: Do not use the address as source address for any outgoing packet unless explicitly specified. The default value is false.”
You can verify that it works by running a sniffer or from command line: tracert -d 169.254.169.254. You will see just one hop.
