I am having problems connecting from Motorola Razr HD phone to my Windows 7 PC's shared folders via ES File Manager. Until recently everything worked fine, I could see/copy files just fine. Not sure what changed, but now I cannot. I am getting either "server not found" or "SMB Service is off" etc.

enter image description here

Other Windows PCs on the same LAN can access shares on this Windows 7 PC just fine. Also the phone can see and access shares on WD WorldBook NAS device.

Any idea why the phone can no longer access Windows PC?

Any help is really appreciated.

Firewall? Is one active? –  Canadian Luke Jun 9 '13 at 2:16
It is active, but it doesn't prevent other PCs from accessing the shares (I guess rules are in effect). Also turning it off has no effect on phone access. Funny thing when I do a LAN search in ES File Explorer - the IP of the Windows 7 PC is found, but I can do nothing with it. –  Yuriy Galanter Jun 9 '13 at 2:18
are you putting in a username and password? –  Frank Thomas Jun 9 '13 at 2:21
Yes I am, but still doesn't help. When I do the same for a share on NAS - it works fine. –  Yuriy Galanter Jun 9 '13 at 2:23
It seems when I reboot the phone - it would work for a while, but then stop again. –  Yuriy Galanter Jun 10 '13 at 13:28

I had an issue connecting with ESFE to a Win7 PC. This did the trick for me: Go to Network adapter configuration -> Tcp IP 4 settins -> WINS -> Enable NetBios over TCP/IP.

ESFE is looking for NetBios over tcp/ip because android probably doesn't natively run NetBios protocol.

Did you add or reinstall some network adapter?... That could cause the NetBios over TCP/IP to stop working because by default it is set to an ambiguous "Automatic" state.

To anyone out there, I was having the same issue with my HTC One M8 smartphone. Any wireless transfer app I downloaded would not work. I altered the TCP IP 4 settings as described above and now all my Android file transfer apps work GREAT!

Keep in mind that Windows7 DOES NOT allow you to view all files that you enable for sharing. Win7 ONLY allows you to view the "Public" files on a network. So, if you want to move files from your Win7 PC to your phone or visa versa, you have to copy the files on your Win7 PC and paste (duplicate them) into the desired public files.

I hope this helps, as I am sure many others are having this same problem attempting to use wireless transfer apps on their android smart phones.

Apparently you need to tell Windows that you want to use the machine as a file server and that it should allocate resources accordingly. Set the following registry key to ’1′:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

and set the following registry key to ’3′:


After making these changes and restarting, I haven’t seen this issue arise again. Fixed

It might massively help to have a gist of the contents of that link in your answer - link only answers would be useless should they link you have linked to go down –  Journeyman Geek May 19 at 3:30
@JourneymanGeek I am aware. Posted from the phone to share as soon as I knew it worked. Will copypaste when I get to my laptop. –  Yuriy Galanter May 19 at 4:10

I have had the issue described above. The LAN (smb://) connection from ESFE worked the first time I tried it and then (the next day) problems... I could see the server (under LAN) and after waiting a long time it would show the shares, but would not access any files.

(Many hours and ill-advised actions later) I realized that that when I had had a successful connection the first time I also had a VPN running on the android device (torguard, if you're interested). I started torguard and... voila!

I don't know if this will help anyone else, but running a VPN works for me.
