Guest can't access hosts's SMB shares

[iAdjunct]

I'm new to unRAID. Right now, I have two servers using various hardware I have. Let call them:

 

- Server A - my file server

 

- Server B - my VM server, which is running, among other things, a Win10 VM with my 1080 Ti passthru and bridged networking

 

I have many "computers," both real and otherwise, but for now I'll reference two:

 

- Computer X - the aforementioned Win10 (Enterprise) VM

 

- Computer Y - a real Dell laptop, also running Win10 (Home)

 

So here's the deal.

 

Computer X and Computer Y can access the SMB shares on Server A, but only Computer Y can access the SMB shares on Server B.

 

Computer X, despite being a VM on the very hardware, cannot access the server.

 

Some notes:

 

- There's no appreciable difference in server configuration (both have running arrays, both have file shares, both have user accounts, etc)

 

- The subnets all work out (I'm 10.10/16, my Dell and Win10 are in the DHCP pool at 10.10.10/22, at the unRAID servers are 10.10.81.x)

 

- There appears to be no difference in Windows security settings

 

- Computer X can ping Server B and access the web administration interface, so there is connectivity / routing

 

So...

 

Why can't Computer X talk to Server B?

Can you access the shares via ip address?  Or is the that you can see them but not access them?

When I type in `\\10.10.81.2` Windows tells me it cannot connect. When I ping that IP or go to it in the browser, they both work.
