Hi experts,
I apologize in advance for this being a little harder given I am trying to help a friend figure this problem out. I spent quite a bit of time remoting in with no success. I probably wasn't helpful, because I am not that familiar with WIN7.
Anyway, the network consists of three computers: One running Windows XP Home, one running WIN7 Pro and a laptop running Windows Vista Home. I know, not the best setup. They are connected with a Linksys router I was unable to access using the username and assword of "admin" and "admin" or a blank username and "admin" for password.
The program that needs to have its database shared is on the WIN7 computer. The XP computer can access WIN7 with no problem. The laptop can access the XP computer and vice versa, but it CANNOT access the WIN7 computer.
When I first started trying to help, none of the computers could ping each other. After uninstalling Norton360 from all computers, they could all ping each other. The inside IPs were basically 192.168.2.xxx and the default gateway for all was 192.168.2.1. All three computers obtain their IP, subnet mask and default gateway from the router.
No matter what we tried, every time the laptop computer tried to browse to the WIN7 "main" computer, it asked for a username and password. We tried every imaginable combination. We tried turning simple file sharing on and simple file sharing off. All of the computers could see the other computers in the network window and the two "good" computers could click on any of the other computer icons and see the shared folders, but the laptop could not. Even though the laptop could see the other two computers on the network, it could not see any computers if it tried to map a drive. Each computer was using MSHOME as the workgroup and the WIN7 was set to Work Network and Discover was turned on. I doubt it matters, but the WIN7 computer was 64-bit.
I hope this is enough information to start. Thanks for any help.
