Can't connect to Win7 shares from Android, OK from other PCs

[itm]

I have several shares defined on my Windows 7 x64 desktop which are accessible from all other Windows 7 machines on my network. Until recently those shares were all accessible from my Android devices using ES File Explorer (Nexus 10, Nexus 7, Galaxy S4). Today I get this error when I try to connect to any of these shares from ANY of my Android devices:

"Login fails. This may be caused by:
- WLAN is off
- SMB Server is out of network scope
- The IP is invalid
- Blocked by the firewall
- SMB service is off"

I connect to the server from ES File Explorer using my usual Windows id/password (which is an Admin account, and has full access to the shares). All of the shares are listed correctly in ES File Explorer, but I get the error above when I tap on any of them to view the sub-folders.

Up to now I have been connecting to these same shares without any problems, using the IP address and my login credentials. I even tried creating a brand new share, will full access permissions granted for my user id. This share is listed fine in ES File Explorer, but once again I get the error above if I try to connect to it.

I also have Windows 2008 Server and Windows 7 x32 desktop machines on my network, both with shared folders. The Android devices have no problems accessing the shares on either of those two machines. It's just this one Windows 7 x64 machine that is the problem (but only for Android devices - other desktops on the LAN can access the shares no problem).

My Windows 7 (32-bit) laptop is also connected to the LAN via the same wireless access point, and it has no problems accessing the shares on the Win7 x64 machine.

I have disabled the Windows firewall, and also disabled the AVG antivirus protection, but it didn't help. I'm not running any other AV software. I also have Oracle Virtualbox and VMWare workstation installed, but don't know how/if that would interfere with anything. I've tried disabling all of the virtual network adapters associated with these applications, but it didn't help.

Any ideas??

I've seen the virtual box and VMware cause connection problems in the past but not file access problems.

AVG on the other hand,...to be sure here you would need to uninstall AVG using the special uninstall tool made for the job.
