Windows shared folder issue

[Ernesto]

Hello.

I need to share a windows 7 computer across 2 LANs. This PC is connected to LAN interface.
I added a virtual IP to my OPT1 interface and a fw rule to allow all the traffic from LANs to the PC's LAN IP

When i try to access the shared folders from my other Windows XP machine my pc asks for password but then drops immediately with an "authentication error" message.

RDP (remote desktop) is working, WampServer too.

any advice?

Thanks

have you tried to add computername\username format or just username?
