Hi, I have this weird problem, I know that you can use shared folder from VirtualBox but I'm trying to setup a network and I've been testing using My PC with 2 Virtualbox machines

In the two VirtualBox machines there are two network adapters:

1) With NAT connection for internet
2) Host-Only With these statics IPs
2.1) PC1: 192.168.56.101
2.2) PC2: 192.168.56.102

The Host-Only adapter is to be able to see each other PCs in the network with the Host/Guest Virtualbox machines

1: PC0 Host PC (Two accounts, my main account and the second one is PUSER with password)
2: PC1 (VirtualBox) (Two accounts, main account and the second one is USER1 with password)
3: PC2 (VirtualBox) (Two accounts, main account and the second one is USER2 with password)

I can connect PC0 to PC1 and PC2 without any problem, with or without password, zero problems here, everythings is cool!

The problem is when connecting PC1 and PC2 to PC0, either using password enabled or without it but with the PUSER added to the shared folders permissions
If I set permissions in PC0 to folders to EVERYONE, PC1 and PC2 can connect to PC0 without problem

If I connect for example PC1 to PC0 using this command line:

net use <driveletter>: \\<PC0_OR_192.168.56.1>\<sharename> /USER:<PC0_OR_192.168.56.1>\PUSER <password> /PERSISTENT:YES

It shows this error:
System error 86 has occurred. The specified network password is not correct

Searching on internet I found this: windows - Windows7 - ?The specified network password is not correct.? when the password is in fact correct - Server Fault and the value was already that one
I also reset the Group Policy with this guide: Local Group Policy - Reset to Default, still problem persist
