Hey,

I have a home network consiting of 4 PCs and 2 Wireless Routers

D-Link Router
(xxx.xxx.1.1)
NetGear Router
(xxx.xxx.1.2)
-----------------------------
Media Centre Upstairs w/ Windows XP MCE sp3 & Windows 7
(xxx.xxx.1.3
Netbook w/ Windows XP sp3
(xxx.xxx.1.4)
Meida Centre Downstairs w/ Windows XP MCE sp3
(xxx.xxx.1.5)
Laptop w/ Windows Vista sp2
(xxx.xxx.1.6)

-----------------------------

The 2 Media Centres are each connected to a router, and the routers are connected to each other via ethernet port 1

D-Link router is primary, and has internet connection.
it has DHCP turned on allocating IP address from xxx.xxx.1.3

The Netgear router has DHCP turned OFF

Using this configuration i am able to have 2 Access points and expand the wifi area allowing the portable computers access from upstairs Or downstairs on seperate access points.

This has been working fine for me so far, however...
I am not sure where the problem lies, but for some reason the Media Centre downstairs (xxx.xxx..1.5) can not access the files from the one upstairs (xxx.xxx.1.3), but the the upstairs machine can access files shared by the one downstairs...

all other PCs can access all files, on all PCs
when the network was first created i had to enter the username and passwords for the PCs each PC trys to access as is normal, however on xxx.xxx.1.3 there are 2 operatng systems, and the 2nd was added AFTER the network was first created. and to avoid confusing the other PC's i changed the username and passowrd from the first OS (XP MCE) to the same as tthat of the new Windows 7 OS

but since the downstairs Machine (xxx.xxx.1.5) has allready accepted username/password details for the Duel OS Machine (xxx.xxx.1.3) (and those details are now WRONG) i cant get it to accept new ones.

This is where i believe the problem lies, however i dont know why the other computers are not being affected by this issue, as i said earlier, the netbook and laptop can still access files from either OS on the duel OS machine (xxx.xxx.1.3)

I would be most gratefull if somebody could provide a solution...
thanx in advance

Quick, ordered troubleshooting for the one‑way share reported by . and pointed at credential caching and network layout — the steps below apply to an XP/Vista/Win7 era home LAN and are written to be safe and reversible.

Clear any saved credentials and persistent mappings first (the most common cause of “stale” authentication). On Windows XP open the Stored User Names and Passwords dialog and remove entries for the remote host, then remove any mapped connections with net use. On Vista/7 use Credential Manager or cmdkey to delete stored credentials; reconnect with explicit credentials or map the share supplying /user: so the right account is used. 

rundll32.exe keymgr.dll,KRShowKeyMgr     (XP Stored User Names and Passwords)
net use \\192.168.1.3\ShareName /delete
net use * /delete
cmdkey /list
cmdkey /delete:192.168.1.3
net use Z: \\192.168.1.3\ShareName /user:UpstairsUser password

(support.microsoft.com)

Confirm basic connectivity and correct router wiring/role next. From the failing client check reachability and NetBIOS name resolution, and verify the second router is acting as an access point/switch (LAN‑to‑LAN, DHCP off or reserved IP) rather than creating a separate NAT/subnet — wrong port/wiring or AP isolation can produce asymmetric access. 

ping 192.168.1.3
nbtstat -A 192.168.1.3
ipconfig /all

(lifewire.com)

Finally, check SMB and firewall blocking. Older XP clients require SMBv1; many modern Windows installs disable SMBv1 for security, so enabling it is a last resort and must follow Microsoft guidance. File and Printer Sharing (TCP 445 and NetBIOS ports) must be allowed through the local firewall or the share will fail even when IP connectivity exists. (learn.microsoft.com)

Typical effective order: clear stored creds → remove persistent mappings → verify LAN→LAN/AP wiring → test ping/nbtstat → check firewall/SMB. If deeper diagnostics are needed, useful outputs are net use, ipconfig /all, arp -a, and nbtstat -A <IP> for the failing client.

Windows 7 does not "Officialy" support file sharing with anything below Vista Home Premium. XP has support for Windows 7 Ultimate only. It does sometimes work fine although Windows updates will change settings etc. so one day it will be working and the next it won't.

As for the authentication, I belive that once it has authorised with a username and password even with a user/pass change it will still allow authentication UNLESS you are running an Active Directory server.

i HAVE FOUR COMPUTERS oops sorry on a network using a adsl box and a ethernet router. I add and take away two portables to this system;
OK so it works but one of trhe reasons that it works is that I was advised a ,long time ago by a microsoft engineer! to use static IP addressing rather than DCHP! I have toadmit he was right. each computer has its own different 192.168.xxx.xxx static IP address and all other units on the systemhave theior ,own (eg a network HD etc) address,; DCHP works where one computer is totally in control but ,in my expereince does not work where more than one computer competes for control.

Try setting all the IP's as static rather than dynamlic.
