Does Wingate do a port 137 scanning on the network?

[teowx82]

Hello,

I had installed Wingate 6.6.4 on my server as a proxy using WWW proxy. I also disabled all the other services. After I configured the proxy to redirect the client request to my Web server, everything was working fine. Recently, I configured the Symantec EndPoint Protection antivirus to point to a centralize update server to get definition update, and Wingate trigger a port scan of the port 137 to all the servers on the network.

Anyone know what had caused the trigger of the Wingate to conduct a port scanning??
