Hi all-
Let me say thanks in advance to any help you can give me.
I have a peer to peer LAN that is having trouble. I have 6 Vista machines, 4 XP Pro + 1 XP64 machines, 1 Win2000 (not upgradeable-special duty) machine and 2 Network Attached Storage machines (Dell Powervault 715n). They are connected by 1 D-Link DGS-1024D & 2 DSS-24 switches and connected to thte internet through a Linksys WRT310N router. I am working to get to a fully Gigabit Network as $$ permits. Older machines are attached to the 10/100 switches and newer machines capable of gigabit are attached to the gigabit switch. I've tried mixing this up with the same outcomes.

Here's the problem- VIsta machines are sometimes seeing the XP and NAS boxes and sometimes not. All boxes are set (currently) to Static IP- tho I have tried DHCP as well. I have placed all boxes in WORKGROUP- private network, with only Network DIscovery and FIle Sharing on. I fired up one Vista this morning and ran Photoshop- It saw the NAS box so I retreived the file I needed. 10 minutes into working on that file, I needed another one. This time the Vista box didn't recognize anything on the network except the other VIsta boxes- no XP boxes, no NAS. I understand the issue regarding LLTD and have d/l'ed the lltd update files for the XP boxes, but I have no idea why the vista box doesn't recognize the NAS.

This problem is further amplified by an annoying fact that from within Norton Internet Security's network map, ALL THE BOXES SHOW UP! I have set NortonIS to fully trust all items in it's network map. So I do not know how it could be a firewall issue. Can anyone tell me how in the world NIS sees my network, but Vista itself doesn't???

I have studied every MS Knowledge Base article I could find as well as as many forums as I could. I am at a loss and either am missing the most obvious things or have some little checkbox unchecked.... =\

Anyone up for a challenge??

Thanks-

PS-I can ping each NAS box from VIsta- Here is the details from IPCONFIG:
