TCP445 is Windoze LSASS-File Sharing

TCP135 is Windoze NetBIOS

TCP139 is Windoze File Sharing

UDP137 is Windoze NetBIOS NS

TCP1025 is Windoze Messenger RPC

UDP1026 and UDP1027 are Windoze Messenger spam ports

TCP5000 is Windoze Universal PnP (majorly hackable)

hi daveford123, what do you want to do? block or enable file sharing through firewall? btw, enabling file sharing throught firewall is NOT a good idea, and not only related to the ports listed here. regards, bbao

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

Few days ago, our file server crashed, no one was able to access their shared group drives from file server. After a restart, it is back to normal and hasn't crashed again yet.

But I want to monitor the windows file sharing service and file sharing ports, so at least it can trigger alerts when those ports are down or the file upload/download/delete fails.

We are using "nagios xi" to monitor all servers, and it monitors FTP server on port 21, which is wrong for windows fileserver!


Thanks,
