Network Access slow on Norton Internet Security 2010


I have been running Norton Internet Security 2010 on a small workgroup of Windows XP computers.
The computers are running Medical Software, where it needs to connect to the server using a UNC path:


The software company will not support mapped drives, so I can not test if that fixes the issue.

The issue is that when I open the software that is installed on the local machine, it goes to the UNC path for data and to load some extra modules, but the software is taking 2 mins + to open.

I suspected firewall, but when I disabled it, the issue continued to happen. When I disabled AutoProtect on the antivirus, the issue went away.

I have tried added the locally installed program to the AutoProtect Exclusions, but am unable to also add the UNC path (Norton restrict this)

Please someone help.

Is the network currently set as trusted? And you added the app's exe files as exclusions?

This is why I don't like Norton, and software based firewalls in general. I would consider another alternative to Nis, perhaps MS security Essentials, avast or Nodre for testing..

Did you try a directory exclude (not just the .exe but the entire contents and subfolder)?

Unfortunetely Synmantec's AutoProtect feature only supports exclusion of mapped network drives. The only other solution to prevent the real-time scanner from repeatedly scanning the modules is by temporarily disabling AutoProtect which is a no-go.

I'm not completely sure what you mean by the software company doesn't support mapped drives. Do you mean once the software is opened it cannot point to a UNC path?

You can't map a network drive to \\SERVER\data on the local machine, then add the mapped drive as an exclusion in AutoProtect?

I think this may be an issue with how Autoprotect interacts with networked applications regardless of whether they're being accessed from a mapped drive or via UNC path.  I currently have a client experiencing nearly identical symptions -- extremely long load times for a network app, but disable autoprotect on the server and everything runs lightning fast.  I believe one of my colleagues finally got the issue escalated to tier two after fighting this for days...
