Symantec Endpoint Firewall

Posted on 2009-05-15
Last Modified: 2013-12-09
Symantec Endpoint firewall is blocking client computers from using File and Print Sharing.  I am able to browse to client computers, but unable to access any shared files.  This is a managed version of Endpoint, and I have created rules for the firewall, but to no avail.  Does anyone have any suggestions?  Screen Shot attached.ad

You need to create two FW rules based on this KB article:

Get rid of that POS. Nothing more than malwarebytes and Windows firewall is required.

11.0.4014.26 is the version I am using.  I have created those two rules in the Mgt Console, but still not working.  Any other suggestions?

The rules look correct. Did you say that you can browse the clients but not able to open the shared file/folder? do you get an error message or what?

Yes, I can browse to the machine, but unable to access any thing that is shared on that machine.  The error I recieve is:

\\name\shared is not accessible.  You might not have permission to use this net2work resource.  Contact the administrator of this server to find out if you have access permissions.

Not enough server storage is available to process this command.

But if I uninstall SEP  I am able to browse and access files

I found the issue.  It wasn't firewall rules at all, but rather IRPStackSize needed to be changed.  You would think that Symantec would have fixed this issue.  Because I like to have access to all the computers on my network through administrative shares.  Guess I will just have to wait to see if this is the right one for me.  Thanks.
