Frustrated with odd sharing behavior after a move, Windows 7 and Vista, and network name differences connecting to the same network

Thanks in advance for any guidance.

I have a client who has just moved, and for whom I reconnected everything charged with making it all work.  There are three PC's, 2 are Windows 7 Pro and one is Vista Pro.  One of the two Windows 7 PC's hold the company shared data, and the others have network shares to the shared data, located in the public folders of the PC.

After the move, the other PC's can no longer connect to the shared data. Network mapping to the shared/public data was impossible. All PC's are connecting wired to the same router/network. On each PC,  All sharing settings are Work and set properly to share.  The sharing PC can 'See" and connect to shares on the other two, but Neither can 'See" or connect to the sharing PC.  They are all on the same Workgroup. Also, the shariing PC and the Windows 7 PC that can't establish a map are on the same HOME Group.

 This is what is truly confusing... :   When looking to the network adapter settings, the the two PC's trying to connect are connected to LAWNET-2.4, which is  the name of the wireless network, though the connection is confirmed as only wired. The network to which the sharing PC is connected is something else which I can't remember, but I will update as soon as I look again in the AM (business is closed).  I strongly suspect that this might be the crux of the issue.

I've spent three hours trying to figure this out, to no avail.

Any hints would be welcome to solve this frustratingly strange issue.  I am prepared to be embarrassed, so any ideas welcome.

Did you connect up the Wireless router to the main router correctly?  LAN port on Wi-Fi to LAN port on network, give the Wi-Fi a static IP on the network and turn DHCP OFF on the W-Fi router.

are they using a HOME group or are they using a work group.. Network set as WORK or HOMEGROUP?
Mark LitinOwnerAuthor Commented:
The router is a business class CIsco DCP3939B. The access port is built in, but no one is using it.
 The clients are all going through office wiring, and both Windows 7 machines are also being served through netgear gigabit switched.

Home Group is set in the windows pc's, but all PC's are on the same Workgroup called LAWNET.  The network TYPE is WORK in the Network and Sharing Center.

We'll definitely try static ip's on the wired devices.

Will the Home group and workgroup interfere with each other?

Thanks for your quick response!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

From what I gather and surmise a homegroup is just a specialized type of workgroup.  You create a homegroup on one machine, this creates a Homegroup User and you select which areas to share with the homegroup.  The O/S now sets up the shares appropriately You are presented with a key (Password) that the other machines use to join the HomeGroup (they create a homegroup user with this password) and sets up this users shares.. The windows firewall also sets up various allow rules in its network settings (Home/Work/Public)

Homegroup is for Windows 7 and up and is best turned off ( that is, use password protected sharing).

However, you said ALL worked before moving, so it would appear that networking is an issue.

I suggest you use DHCP for connections as that is more reliable over the long haul.

Thanks for the guidance.  As it turns out, the PC that was presenting the data was simply disturbed in other ways not foreseen, and needed to be revamped anyway.  So the data was moved to another PC and presented there.  No problems sharing using standard windows Public folders.

Thanks for the clarification.
