Windows 10: build 9860 Win 7 and XP machine access (solved)

Hi there

Old network problem has re-appeared again in build 9860 W7 and XP machines cannot access W10 machine. W10 machine CAN access W7 and XP.

The XP and W7 machines CAN access W10 when accessed by IP address but it doesn't work by HOSTNAME (or computer name). I am using DHCP so no fixed Hosts files with IP address and Hostname fixed in a config file.

Note problem is connections FROM XP / W7 TO W10 not the other way around. (W8.1 machines work fine)

Now with a bit of Googling and testing you can make it all work.

If you BLOCK port 139 in the windows 10 firewall it all works fine again -- seems the older computer systems use both ports 445 and 139 while Windows 10 only wants to listen to port 445 - so if you block port 139 the older OS'es switch to port 445 which works properly.

If you switch OFF the firewall you'll get a problem again because the older OS'es will send out via Port 139 which W10 isn't listening for - but won't get a notification that the request is not accepted so they won't fall back to port 445.

First time I've found that testing is EASIER with the Firewall ON !!!!!!.

You do NOT need to lower the encryption security from the default 128 bit (even for XP machines) in the file sharing setup in Network connections (control panel). Just block port 139 (on the W10 machine).

COMPATIBILITY CHECK FOR WINDOWS 10

That's ok from PC's with Windows 7 and 8, what about equipment with xp installed? Granted this will not be a free upgrade to Win 10, but I would like to know if the machine is capable of running the new OS before I go out and buy it. Basically, is there
a downloadable tool that I can access and run on my xp machine to test for compatility with win 10?

 

Win7 AND XP Mode recover from Win 10 upgrade

I recently upgraded to Win 10 from Win 7 professional W/XP mode virtual machine. Too late, I discovered that Win 10 does not support the XP mode. I know I can "recover" Win 7 (it has been less than 30 days), but will I get my XP virtual machine back along
with the applications that were on the virtual machine?

 

Something tells me that Microsoft will not find it in their best interest to make NetBIOS backward compatible with XP, Vista, Windows 7, and Samba3 platforms. They have moved on to implementing SMB2/SMB3 and so has Samba with the release of Samba4.

I found it easier, in my three PC home network environment, to simply disable NetBIOS and use the each PC's hosts file with static IPs for name resolution. With Windows (since Windows 7) using "network discovery", my PC are automatically seen in "Network". I guess they would be seen even if they were in different workgroups, though I've never tested this.

So I have officially kicked my XP, Vista, Fedora, CentOS 6.x systems to the curb. I'll keep Win7 around a little while longer. I now have to spend 2 weeks of my life doing a CentOS 7.x install since it comes with Samba4. And when Win10 is officially released all PCs will be migrated to the new platform. Thereby assuring full compatibility. These mixed Windows network environments are just to painful to deal with.

 

For a fellow CentOS user: Did you know that CentOS runs extremely well on Hyper-V virtual machine on Windows 10: Hyper-V VM - Install CentOS Linux in Windows 10, no networking issues with Windows 10 host.

The best part is that CentOS version 7 has the required integration components included in install image, it is one of the Hyper-V's officially supported Linux guest operating systems.

Just trying the new release of OPENSUSE (13.2) released yesterday. I'll have a go with CentOS later.

Thank you very much for the detailed explanation and the solution I've been seeking for several weeks and countless hours.

(Now, if only I can get as satisfactory a resolution to my 16-bit program problem...)
