Norton blocking a network drive?

I have a network with 2 Win XP machines and two 1 tb networked hard drives on a wired switch. The switch is connected to a router that has wireless. I have a Windows 7 laptop that connects to the wireless router. There is also a wired printer in the mix. The wireless router connects everything to the internet. Of possible consequence is that everything is running Norton Internet Security.

All three computers can get on the internet and print to the printer. The two XP computers can use the drives (which have been mapped) as though they are local. The Win 7 laptop does see the drives - I can get to the web page and the list of devices shows both drives as media drives, and when you go to the "devices" screen. They also show up in the network list. But, I can't access them. No matter how I approach it, whenever I try to access the drives by their name, the system tells me that it can't find the path. I CAN see the shared drives / directories on at least one of the other computers.

 

The only thing I have changed on this computer is that I recently upgraded NIS to the current version. About shows Version 19.1.13 The License agreement shows version 12 (This is the full retail.)

 

Any ideas?

 

You can try temporarily disabling Norton to ensure that this is in fact the problem. It does seem likely though, if it was working before and now it isn't...

Are there in logs in the history under firewall or Intrusion Prevention that have any correlation to the times where you try to connect to the drives?

I tried disabling the firewall, but it didn't make a difference.

 

I turned the computer on and tried to connect to the drive, and got the expected message. I checked the log and saw the normal stuff. I did click on the "connected to a protected network" and tell it to trust incoming connections from the network.

 

I waited about 15 minutes, leaving the computer alone, then tried again to connect to that drive. It didn't work. But there are no entries in the log.
