SEP Firewall lead to access delay on the network share folder

Dear All,

We are using SEP 14 MP1 . When enable default firewall policy, everytime user access the nework share folder created at another cilent pc will take about 20~30 seconds to access.

This happen on all cilent PC network folders.

If we disable firewall policy in SEP, the issue is gone.

our cilent PC use Window 7 Professional SP1 .

Anyone face the same issue?

Thank you for your reply in advance.

Best Regards,

Boris
