Since I am asking two questions I am upping the number of points<br />
<br />
I am running Windows Server 2008 on my network. &nbsp;When I try to go to a \\servername\share I get blocked by the outbound firewall. &nbsp;Example<br />
<br />
SererA has the share I am tring to access from ServerB. &nbsp;From ServerB I click Start/Run and type \\serverA\share when I disable the Firewall on ServerB it works (yes, the firewall on ServerA is enabled).<br />
<br />
The questions<br />
1) &nbsp;What port do I need to enable or Firewall rule so this works in a secure fashoin on my internal network.<br />
2) &nbsp;How can tell what port a firewall is blocking in the future? &nbsp;Is there a utility or technique?<br />
<br />
If you have the answer to part of the question please respond and I will split the points accordingly.<br />
<br />
ps: Name resolution works just fine I have tested that several ways nslookup, ping -a, both firewalls down it works and with Firewall up on serverA name resolution works.

Windows Firewall

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls
