I have five network connections:
Wireless Network Connection (Intel PRO/Wireless 2200BG)
- Client for Microsoft Networks
- Symantec Network Security Intermediate Filter Driver
- Deterministic Network Enhancer
- File and Printer Sharing for Microsoft Networks
- QoS Packet Scheduler
- AEGIS Protocol (IEE 802.1x) v3.7.5.0
- WLAN Transport
- Internet Protocol (TCP/IP)
Local Area Connection (Broadcom 440x 10/100)
- Client for Microsoft Networks
- Symantec Network Security Intermediate Filter Driver
- Deterministic Network Enhancer
- File and Printer Sharing for Microsoft Networks
- QoS Packet Scheduler
- Internet Protocol (TCP/IP)
Local Area Connection 2 (Cisco Systems VPN Adapter) <-- I don't use this unless the other VPN server is down
- Client for Microsoft Networks
- Symantec Network Security Intermediate Filter Driver
- Deterministic Network Enhancer
- File and Printer Sharing for Microsoft Networks
- QoS Packet Scheduler
- Internet Protocol (TCP/IP)
VPN (WAN Miniport (PPTP)) <-- This is the one I regularly use
- Internet Protocol (TCP/IP)
- QoS Packet Scheduler
- File and Printer Sharing for Microsoft Networks
- Deterministic Network Enhancer

The last thing I tried was unchecking "Symentec NSIFD" on the Wireless Network Connection only. Doing so caused that app to lock, and when I stopped it with task manager, it took Explorer with it. I rebooted, checked the setting and it was unchecked. At this point, my networking (wired and wireless) is working at work. I haven't been able to see if everything still seems to work at home.
I typically use wired at work and wireless at home, although, sometimes I need to use wireless at work and sometimes wired at home. At both places, I am logging into the laptop. There is a domain at work, but my laptop is not part of it. At home, I typically have a VPN connection open to work (which was working fine last night after installing NIS). The wireless at work is a Cisco AP which does authentication via the domain controller, I think.

I installed the NIS 2009 trial at home on a laptop with XP SP3. Both the wireless and ethernet networking work fine. But, when I shut down the laptop and bring it to work, neither the wireless nor the ethernet work. In fact, neither adapter even shows in ipconfig, and the wireless monitoring application says there are no wireless adapters in the laptop. If I uninstall NIS, the networking comes back.
I've tried disabling all the features of NIS to no avail. I disabled the Symantec Network Security Intermediate Filter Driver on the Wireless Connection Network Properties (and had to reboot when the app locked) and now have all my networking back. But, I assume I am lacking some protection. Is there a way to get this all working the way it should?
Chris
I'm assuming that you've tried running the Norton Removal Tool and reinstalling. Since this happens only when you make modifications to the wireless adapter, have you tried updating the driver to your adapter? When you describe the problem that you see, can you take screen shots of what you're describing? Also, try reseting the stack:
- Start, then run
- netsh int ip reset c:\resetlog.txt
- click OK
- Then try renewing your IP
To clarify, when you login at work you choose "this laptop" to login? Also, are you booting fresh or are you resuming when you start up at work?
Chris,
There's an interoperability problem between the Symantec Network Intermediate Filter Driver and the Deterministic Network Enhancer which is part of the Cisco VPN. This Symantec driver is not involved with any traffic filtering so you do not lose protection by disabling it (at least for the 2009 release). It participates with the home networking feature and performs local node detection so that feature won't work with the driver disabled.
The problem seems to be sensitive to the installation order so you might try installing NIS first and then adding the VPN on top of that.
We use the Cisco VPN internally and generally don't have any issues. It seems to be some rare configuration problem.

Okay. So, I unistalled NIS and ran the NRT (which I had not done before since 2009 was the first version I had installed). I updated the wireless driver and then couldn't even connect to my AP, so I went back to the previous version.
I uninstalled the Cisco VPN and installed NIS. Now, connections at home and work are fine. As I mentioned, I don't usually need that one, so I am just going to leave it unistalled for now.
Thanks for your help.
Chris
Could you list all of the items that you see there? Also, instead of uninstalling, what happens if you only uncheck "Symantec Network Security Intermediate Filter Driver" (I'd restart as well) does that correct things? When you plug in at work are you wireless or wired? Log in through VPN or how do you log into your network at work? What type of Network is it?
