Problem here is the InetAddress.isReachable().

Windows firewall blocks the kind of packets that this method uses on ICS. To 
fix this method needs to be removed and the client should rely on it's ability 
to connect to the server to determine host accessibility.

This will mean the error messages will be less specific (IE Unable to connect 
and/or server not running" but will mean the program is usable on Windows Vista 
and above without the person having to disable their firewall.

time or tools to test...

Workaround for this On Win7:  Open "Windows Firewall with Advanced Security", 
Click "Inbound Rules", Click "New Rule", Select "Port" type, "Next", TCP & 
Specific local ports: 7, Next, "Allow The Connection", "Next", Tick them all, 
"Next", Name it and click finish. 

The app should now work.

I'm also getting the following error:

'The host is unreachable: 2500 ms time out (-3)'

This is with version 1.0.3-r3 on a Galaxy S3. The server is running on Windows 
7 64-bit. I can ping my phone from the PC. I've added a new rule into Windows 
Firewall as described in the post by minuszer, but it doesn't help.

I am seeing this too. If I turn off the windows firewall, I don't have any 
issues. If I create a firewall rule to allow the ports I see being used in 
wireshark (41788 and 7), it still doesn't work. 
The line from heino* describes my situation too:
