使用sqlserver.management.smo并与运行vpn programm发生冲突

下面你看到我的程序的一部分，以获取我的网络中的sql服务器。

below you see part of my program to get the sql servers in my network.

正常它工作正常，我得到了服务器。但是当我运行vpn programm

normaly it works correct and i get the servers. but when i am running the vpn programm

同时检查点scu remote时，我没有得到服务器列表。

check point scu remote at the same time, i get no list of servers.

需要帮助才能看到冲突。
