I am having similar problems. I have a home network with two computers attached (plus the 1600n), a generic-brand desktop and a Dell laptop. I installed the 1600n software on the desktop first. That computer works fine. I then installed the software on the laptop. The laptop prints beautifully, but can't see the scanner on the "Network Scan Manager" software. Let me know if anyone figures out this behavior...

I am having the same problem except I haven't been able to have any client find the printer via Network Scan. Support sent me a new printer, same problem. Can ping, can access the maintenance web page; Network Scan says device not found when browsing or connecting directly (typed IP address).

Figured it out. If you have a virtual network device like the kind used for VMWare Virtual Machines or SonicWALL VPN software it looks like the Scan Manager defaults to try to go off of those. Thanks to Ethereal I saw it try to go off of a non valid IP address as a source. So in addition to making sure all your FireWall programs are setup you might also have to disable your VPN and Virtual adapters in order to get it to work properly. Hope this helps some of you.

That did the trick. I have two VPN adapters installed for various testing that I need to do.

I disabled both, and the Network Scan utility connected right up.

THANKS!!!!!

So, does that mean you cannot use Network Scan while your VPN adapter is enabled?

If so, that may be a fix, but not a practical one!  I need to have my VPN enabled, and still be able to use Network Scan!

That is what I experienced. If you have your SonicWall Virtual Adapter enabled that is the device Network Scan will try to use (regardless of if it is active or not; active as in an establishment of a VPN connection, inactive being having an IP address of 223.1.1.x).

Using Network Scan over a VPN connection might work.
Now I haven't tried it but this might be a beneficial feature if you want to use Network Scan over a VPN connection (i.e. you are working at home and you want a co-worker to scan something in for you. Since the Virtual Adapter will have a valid IP address when the VPN connection is active it could communicate with the work network.

Using Network Scan on a Scanner on your SOHO LAN while having a VPN connection established at work probably won't work
With that said the more likely scenario doesn't work; where a tele-worker who has a small home network has a 1600n installed and needs to stay connected to their work VPN to get e-mail and work on ERP/MRP business applications but would like to use Network Scan on their small home network.

I'd suggest contacting support and let them know what problem you're experiencing; maybe they've come up with a solution since the last time I called in. If you do find a solution (instead of just work around) please let me know.

Okay, I got this fixed now too. I didn't have an active VPN, but there were two additional network connection calleds the "Microsoft Loopback Adapter" and "1394 Net Adapter." As neither of these appeared to be particularly useful, I disabled both of them (in software), and the Network Scan software was able to detect the scanner once I pointed it to the right IP address. Thanks for everyone's help...
