LAN Problem

[sitonthis]

We have a network of 3 pcs, all running Windows XP Pro.
Each pc has 2 NICs (1 for network connection, 1 for Internet Connection) and I have uploaded a diagram to try and show how it's set up

The router connected to the internet for pcs 2 & 3 is an Asus RX3041
However the router connected to the network I will have to find out and let you know as I don't have access to the room it's in.

Anyway the problem is PCs 1 & 3 can transfer files no problem
PC 2 can transfer files from PCs 1 & 3, but PCs 1 & 3 cannot transfer files from PC 2. They can access PC 2 and see the files but when they try to copy files over the time remaining drops to something like 130 hours and an error message pops up saying copy failed because the network address is no longer available. All 3 PCs will ping each other, and I just can't figure out what is causing the problem. PC 1 Network address is 192.168.0.3, PC 2 Network Address is 192.168.0.5 and PC 3 Network address is 192.168.0.1. The subnet mask is 255.255.255.248 and because the internet is seperate there is no gateway. On the internet connection, PC 3 address is 10.10.10.2 and PC 2 address is 10.10.10.3, the Asus router has 10.10.10.1 (which obviously is the internet gateway for PC 2 & 3, PC 1 has own internet connection) but as i've already said that is seperate. Any help is appreciated

Forgot to mention it's a wired network, and the two modems are from Virgin Media

Ignore the previous diagram it may be overly complicated try this one:

192.168.0.1 on PC3 indicates DHCP is enabled on PC3
and is probably conficting with 1 or both routers.
On PC3 go to start/control panel and run the network setup wizard.
Select connects through a LAN or residential gateway when prompted and complete.

Check the router setup on both routers and make sure DHCP is enabled on 1
and disabled on the other.
Restart your computers to obtain new IP's.

All network ip addresses are static, only the internet for pcs 2 & 3 has dhcp enabled, and the internet addresses for these are 10.10.10.2 & 10.10.10.3. Also is it just me or does the second link point to a picture of evan rachael wood? That's not the pic I uploaded

yes the 2nd pic is rachael wood...

yes the 1st pic is complicate, but so is your network. I'm not sure why you'd want to set things up like that, but it seems to be working for the most part. It sounds like your problem is really in the file sharing space and to tackle that we need to know OSs you are running and what firewall software you have running.

[sitonthis]

All three running XP Pro, Sygate Personal Firewall (which we disabled but it didn't help). We can connect no problems for lan games, and I can do remote desktop it is only when they try to copy files from pc 2 - a message pops up saying network address no longer present

Are they all in the same workgroup?
How many of them have the computer browser service running? (run with 2 max, you want to even use one if there is 1 PC that is always up.

Thanks for the help, but it's sorted. After everything we just switched the connections round on pc 2, so the network is now on the onboard lan rather than the nic card and the internet is now on the nic card and everythings working fine.

thx for the update.
