Endpoint Protection Small Business Edition

Purchased computer that had SEP installed. I set up printer sharing on new computer. SEP is blocking this share, for the old computer. The only way I can get the share to work, is to disable Network Threat Protection. I have tried adding a rule that allows traffic for the IP range of my home network and putting the new rule and #1.

Any ideas on what else I can try? 

Is this happening on all windows plat form ?

If this is happening on one single machine please let me know the version of Sep installed ,

Is this a network printer which is using its own IP controlled by print server ?

Under lan properties check if IPV6 is enabled if yes disable it reboot the machine and then try using printer keeping NTP enabled

Please update if need any further assitance

If this  is NOT, kindly install RU6 MP2

You can configure a blank firewall rull to allow your printing application, or by the IP address if this is a network printer.

Since this is the SEP 12 forum, your actual instructions may be slightly different, but here is the document I found:
