Windows 7 Problem joining W7 to old W7 and XP network

[JJJ]

Hi!
Need help joining a new 7-computer to old workgroup (static ip's, IPV4 etc..) which consists of old xp and 7 -machines...
The problem is, that it is impossible to get a new 7 machine to recognice the old xp-machines in network -if there is even a one "old" 7-machine connected when first time connecting the new one to the workgroup. When the new 7-machine is the only 7-one in the network -no problem xp's found and it will recognice later all computers 7's and xp's.
So, is there any way to get the "wrongly addicted" new 7-machine to recognice also the xp's? The only way I,ve found is to reinstall 7 and be sure that it is the only 7-one when first time joining to the workgroup..

To address the issue you're experiencing with adding a new Windows 7 computer to a workgroup that includes both old Windows XP and Windows 7 machines, and ensuring proper network recognition between the systems, you can try the following steps:
### Solution Steps:
1. Check Network Discovery Settings:
- Ensure that Network Discovery is turned on for all computers. This setting allows Windows to see other computers and devices on the network.
- To check this setting, go to Control Panel > Network and Sharing Center > Change advanced sharing settings.
2. Set Proper Workgroup Name:
- Make sure that all computers are members of the same workgroup. You can check and change the workgroup name in Control Panel > System.
3. Adjust Advanced Sharing Settings:
- Check the advanced sharing settings to ensure that File and Printer Sharing, Public folder sharing, and others are appropriately configured.
4. Use IP Addresses for Sharing:
- If you are using static IP addresses, verify that each computer has a unique IP address within the same subnet.
5. Verify Firewall Settings:
- Temporarily disable the firewall on Windows 7 to see if it is blocking communication with the Windows XP machines. If disabling the firewall helps, you may need to create exceptions for file and printer sharing.
6. Enable NetBIOS over TCP/IP:
- Ensure that NetBIOS over TCP/IP is enabled on both Windows 7 and Windows XP machines. This setting can be found in the IPv4 properties under the TCP/IP settings.
7. Check Computer Name and Workgroup:
- Confirm that each computer has a unique name and that they all belong to the same workgroup.
8. Restart Computers and Services:
- Reboot all computers after making any changes to ensure the settings take effect. You can also try restarting the "Computer Browser" service on all machines.
9. Update Network Adapter Drivers:
- Make sure that the network adapter drivers on all computers are up-to-date.
### Additional Tips:

• Ensure that all computers are on the same subnet.
• Try accessing the XP computers via IP address instead of computer name.
• Consider using a HomeGroup if all computers are running Windows 7 or later.

By following these steps and ensuring proper network and sharing settings are configured on all computers, you should be able to successfully integrate the new Windows 7 computer into the existing workgroup with both Windows XP and Windows 7 machines.
