Win7 (on hyper-v) will not connect to win10 file share

This is driving me nuts!

All of my win10 boxes connect to the file share just fine, even with some higher security settings. Win7 does not. Also, the Hyperv box has the same problem.

Assume:
SERVER = win10 home with the shared folder
CLIENT1 = win7 home running on hyper-v on win server 2019
HYPER = server 2019

All systems have the following services started:
DNS Client
Function Discovery Resource Publication
SSDP Discovery
UPnP Device Host

All systems are on the same network/subnet/workgroup (default WORKGROUP)
All systems can ping each other via IP or hostname (connectivity and DNS are working)
All systems adapters are set to private network/home or work profiles
Turn on network discovery are selected “on” and so is everything else to minimum security on all systems
Windows firewall is completly OFF on all systems

This might be a clue but I dunno:
I CAN RDP from the win10 to the win7 but not vice versa. Shrug.
When I setup a share on the win7 it shows up internally as "\\VM1\share" vs CLIENT1 (but I doubt a DNS issuse because same case with \\IP_address)

What could I be missing???

Thanks for any help.

was it working? a new problem?

It's well-known, XP cannot connect to Win10/11 since Microsoft has blocked it.
My Win7 is sharing networking with Win10/11. no problem.

When the guest OS's network adapter is connected to the Default Switch it can only see shares on the Host machine. This is a W7 Pro guest on a W11 Pro host machine.



To see and connect to shares on any other PCs on the network you need to create an External Switch and use that.



Also, I couldn't get a Hyper-V Windows 7 Home guest to connect to anything until I gave it a Legacy Network Adapter.

I have a number of computers with Windows XP, 7, 10 & 11. With my Windows XP computers I can directly access the shares on my two computers with Windows 11 Pro. However, I don't do it the usual way. I use a network shortcut to each computer to access them. For some reason I can't access my Windows 10 computers that way from Windows XP.

Thanks I fiddled with the virtual switches a bit and got it working. Was a PITA tho because this hyperv box is standalone (just has power and nic connected) and I lost connectivity and had to plug in a monitor, keybord and mouse to mess with it.

Glad to hear that....

Mine's on a W11 Pro laptop, much easier to work on

you are running XP?

was thinking my XP was last one alive in this world.

to improve my XP sharing, it's x86 device that cannot run any x64 (crashing forever). I added Windows 10 x86 (slimdown), dual-boot. the device is still strong. XP runs fast (I think even Windows 7 cannot beat XP speed). when transferring files, it will boot onto Windows 10 which is good sharing networking to Windows 7/10/11.

my XP can run python (v2.8) and excel macros (Office97/2007). new PC, with modern hardware, for somehow, run slower than XP. It's a shame. but XP is dead old. no GPT, no SSD, no USB3. also no browsers. A sorry for XP. XP time seems gone.

I have 5 desktops still working. The two with Windows XP are about 20 years old and have AMD Athlon XP CPUs which don't support SSE2. That means that they aren't suitable for much beyond Windows XP. I think one has Office 97 on it and the other has Office 2003.Also, I just upgraded their HDDs from IDE to SATA ones last year. The SATA controllers only support SATA 1.0 but that is still faster then IDE.

I also built computers back in the 1990's which had DOS, Windows 95, and Windows 98. I discarded them long ago. They're is something about these old Windows XP computers that make me reluctant to discard them at least for now.

my XP came with a package, 4GB DDR2, 2TB SATA storage. 2 DELL XP PRO CD (SP2/SP3 each one, many DELL XP cd-key which never being used) and a suit of Ghost (discontinued).
I never got a chance to install XP on new PC, no XP drivers and no CD/DVD-ROM. no idea to make XP USB stick.
while, for this old XP, ghost is my only tool to image/backup it. It's surprised this XP runs so well. its Win10 x86 was my last achievement on this XP. Its python scripts, macros are too old. they still run well, not broken. If move to new PC, even Windows 7, they will request much re-work. better keep them intact. Anyway, it wouldn't run x64 of Windows 7 or Windows 10/11.
