LAN messenger File Transfer stay on "CALCULATING TIME" error

Anissa Erdman:

Hi anyone!

  Could you help me, please? When I'm sending files to other computer from our network  it's always stuck on "CALCULATING TIME"  and didn't progress anymore. But when someone users sending files to my lan messenger don't have any problem when sending files.

Cornelius Hackett

I installed Softros LAN messenger https://messenger.softros.com

It works. I send  files successfully.

It appears you are experiencing issues when attempting to transfer files using the free LAN messenger application from SourceForge. The problem manifests as the file transfer getting stuck in a "calculating time" status instead of completing the file transfer.

This type of problem is often indicative of connectivity or network configuration issues between the systems attempting the file transfer. Some troubleshooting steps I would recommend are:

• Verify both systems have the latest version of the LAN messenger software and that firewalls or security software are not blocking the application.

• Check that file and printer sharing is enabled on both systems and configured properly in the application.

• Confirm both systems are on the same LAN subnet and network discovery is enabled.

• Try adjusting MTU settings on the NICs to rule out MTU mismatch issues.

• Check switch port configurations are not limiting bandwidth via QoS or speed/duplex settings.

• Attempt file transfers with a different piece of software like FTP to determine if the problem is isolated to the LAN messenger tool.

Let me know if the transfers succeed after trying these steps. Optimizing connectivity and network configuration between systems is crucial for reliable file transfer performance.

Hi!
I have the same problem between two pc's with different windows versions.
From 7 to 8.1 the file transfer works flawlessly, but from 8.1 to 7 it stays on "calculating time" forever.
The pc's are connected through ethernet and are on the same network.
I tried with the firewalls disable on both of them and got the same result as before.
Any ideas on what to try next to fix it?
Thx.

Hi,

Most of my file transfer issues got resolved when I reinstalled it. May be it's worth trying.

Thanks

Kendrick Fahey:

Are there any solutions?

I tried to reinstall but still getting can't send file.

It shows "stay on calculating time"

Brian from Windows support forum:

"This is an older thread, but for anyone else experiencing similar issues with file transfers failing or having very slow transfer speeds, the cause may be a duplex mismatch between the source and destination network ports. It's recommended to verify that both ports are configured for full duplex mode rather than half duplex to resolve this type of problem and achieve maximum file transfer performance. The duplex settings should be checked on the network interfaces of the systems on each end of the file transfer connection. Configuring the relevant ports for full duplex operation can resolve transfer failures and sluggish speeds that are sometimes encountered due to duplex mismatches."

LAN messenger: a port address 50000 conflict on start up

Pete:

How do I fix this error?
When first butting the computer an error message occurs. I have changed the port to 60000 and the same error message happens. What's up?

Error Message: "A port address conflict has been detected. LAN Messenger will close now. LAN Messenger cannot start because another application is using the port configured for use with LAN Messenger."

Hi

This software should now be thought of as 'Abandonware' no one can help you here.
I have tried to get a login for this forum & that does not even work.

I've migrated our office to alternative LAN messenger https://messenger.softros.com

But you will have to download the source code & work out the problem for yourself, sorry for such bad news!!!

Hola, tengo este mismo problema, será que alguien ya lo ha resuelto?
Ayuda... por favor!

Vinod:

Still the issue persist..I'm also facing the same issue. I'm using version 1.2.35. Any solution for this issue..

Maria333:

Our office migrated to Softros lan messenger, recommend to try this app and see if this error happen again.

Randi:

At the command prompt, I ran netstat -noa. Then, tasklist. Netstat -noa would tell you if the port 50000 is used or not, if it is, then it will tell you which PID is using the port. Then, tasklist command would tell you the program file name with the PID. For my case, nothing was using the port 50000, so it didn't help at all. 

Since this issue was only happening to Dell laptop computers we have, not desktop or HP computers, I assumed it was something to do with Dell pro-loaded software. After uninstalling those things like Dell backup and recovery, Dell whatever else not required for the computer to function well, we no longer had this issue.

JoeK:

Just go to the task manager, stop the process for lan messenger, then relaunch app. works for me

k_d:

just go to the task manager, stop the
process for lan messenger, then
relaunch app.
now it will show in notification icons.

Master:

i have two alternate to solve this:

A.

Change the communication port in all machines for LMC
change tcp/udp port from Tool>Preference>network.

in case application is not at all opening then, add below line in the .ini file placed at "%appData%\Roaming\LAN Messenger\LAN Messenger.ini" and open application.

Code:[Connection]

UDPPort=50001
TCPPort=50001

where 50001 is the new port.

B.

Identify & kill the process,which uses 50000 port with following detailed process:
1.From Task manger, open resource monitor
2.Go to network tab and check under tcp connections,PID of the application,which is using "local port" as 50000
3.Note down PID (process ID) of the application and do 'end process' from network tab.
ex. in my case it was 'svchost.exe' with particular PID
4.Now open LMC,it must work.

Hope this info helps everyone like me...

Kasie: 

I tried to open my messaging app, but I got an error message saying there was a conflict with the port it uses. Ports are like mailbox numbers that apps use to send and receive data. It looks like another app is already using the port my messaging app wants to use. How can I change the port my messaging app uses so it doesn't conflict with the other app?

Yolanda:

I'm having the same problem with my messaging app on my Mac computer. On my PC, I found out the ports my messaging app is trying to use are TCP ports 51049, 51062, 51260 and UDP ports 50422, 58980.

The ports apps use can change each time the app opens up. I'm not sure where to find the setting file for my messaging app (on both Mac and PC) that lets me specify which ports I want it to use.

Does anyone know where I can change the port settings for my LAN Messenger app? That way I can make sure it uses ports that don't conflict with other apps. Let me know if you need any help understanding the port numbers or finding the setting files.

Terrence:

I'm having the same problem too on my Windows 10 Pro computer since yesterday. When I used the netstat -abn command to check, I saw that only the lmc.exe app was using port 50000. But when I tried to start my messaging app, it still said there was a port conflict with 50000. Then today, it just started working again without any error. Very strange!
