Work network, main computer, running XP, all other work computers connect to a second (not boot) drive. All work info is contained on this drive. Wireless router, Win7 computers cannot connect wirelessly, but older Win7 computer can connect hard wired. We ran out of ports on the router, so I added a hub. Newer Win7 computer cannot connect to main computer hard wired, older Win7 laptop can. Newer computer cannot "see" main computer.

What am I missing?

I might be mistaken but I think some versions of Win7 are fairly limited in their networking capability. I suppose you could be running into that. What versions of Win7 can and can't connect?

 

[Quo Fan]

Older is Win7 Pro, newer is Win7 Home Premium.

I know that some network service was removed from Home premium, but I can't remember what it is.

There were no network services removed from Windows, just the ability to join a domain which has always been a differentiation from the home and professional versions, all the way back to Windows 2000.

The network topology could be affecting this. I assume you haven't really installed a hub and it's actually a switch? Is the wireless set up as a wireless access point, or is it as a wireless router? And have you made sure to set the network as a "home" or "office" network to ensure it isn't blocking anything?

Getting closer. It can now "see" the computer, but when I input the username and password I get the wrong username/password message.

I called it a hub, but it is a switch.

I remember something about local security policy, but can't remember quite what it is, and I think I have to edit the registry or something.

Sounds like authentication problems, not network problems. Is the machine joined to a domain?

 

[Quo Fan]

Problem solved. Edited the registry to include the LMCompatibilityLevel dword.

Boss is happy, my job is safe for the rest of the day.
