Failed to post. Error code 10054. Unknown Status. Unable to establish session.

Cause

While synchronising data, the Maximum Transmission Units are less than the recommended number.

Solution

It is recommended that the Maximum Transmission Units should be set to more than 1500 for tallynet.tallyenterprise.com.

To set the maximum transmission units you need to download the TCP Optimizer from http://www.speedguide.net/downloads.php.

  1. To download, click the link Download.com and follow the steps as directed to save the SG TCP Optimizer file.
  2. Double-click the TCPOptimiser.exe
  3. Click Largest MTU.
  4. Enter tallynet.tallyenterprise.com in the URL field.
  5. Click Start.

The TCP optimizer pings tallynet.tallyenterprise.com to display the largest non-fragmented packet of data sent, and suggests the Maximum Transmission Units (MTU) you can set for your system.

To set the maximum transmission units

  1. Click General Settings.
  2. Check Custom Settings.
  3. In the MTU field enter 1500.
  4. Set MTU Discovery to No.
  5. Click Apply Changes.
  6. Click OK in the Apply Changes window.

The SG TCP Optimizer window displays a message Would you like to reboot for changes to take effect? Click Yes to complete the settings. The changes will take effect after rebooting.
