"Device doesn't exist on the network" - Windows 95/98/NT4, NTLMv2

[Mantas Mikulėnas]

So I have two VMs in VirtualPC. (But I don't think the fact that they're
VMs matters.) On both of them - Windows 98 SE and Windows 95 - I
installed NTLMv2, and tried to connect to my host PC (Windows XP Pro SP3).

The problem: It only worked *once*.

The first time I clicked on my host PC (inside the virtual PC's "Network
Neighbourhood"), it opened - it showed all the shares, I could even
browse them.

Then I closed the window, and it stopped working. Now every time I try
to open my host PC from the virtual one, it says:

[X] \\THINK is not accessible.
This device does not exist on the network.

BUT the host PC says that the login was successful:

-----BEGIN SECURITY LOG ENTRY-----
Type: Success Audit
User: THINK\Mantas
Computer: THINK
Source: Security
Category: Logon/Logoff
Event ID: 540

Successful Network Logon:
User Name: Mantas
Domain: THINK
Logon ID: (0x0,0x69FD10)
Logon Type: 3
Logon Process: NtLmSsp
Authentication Package: NTLM
Workstation Name: \\WIN98SE
Logon GUID: -

-----END SECURITY LOG ENTRY-----

Right after:

-----BEGIN SECURITY LOG ENTRY-----
Type: Success Audit
User: THINK\Mantas
Computer: THINK
Source: Security
Category: Logon/Logoff
Event ID: 538

User Logoff:
User Name: Mantas
Domain: THINK
Logon ID: (0x0,0x69FD10)
Logon Type: 3

-----END SECURITY LOG ENTRY-----

THINK is my host PC, WIN98SE is the guest, Mantas is my [user]name.

The host WinXP is set to only use NTLMv2.

I have installed NTLMv2 on guest PCs as described in
<http://support.microsoft.com/kb/239869> - and it seems to work fine, as
you can see from the snippets above.

Any ideas?

(Pings travel just fine, and I can browse the guests from host PC.)
