Summary

When attempting to log in to a Laserfiche 8 repository from a Windows 7 computer, you may receive the following error message:

Could not connect to the Laserfiche Server. [797]

Cause

Communication between your Windows 7 computer and the Laserfiche Server may be timing out due to an incompatibility with the Windows autotuning feature and older routers or older firewalls.

Workaround

To disable TCP/IP autotuning

1. Click Start, All Programs, Accessories, and click Command Prompt to load a command prompt.

   Note: In a UAC environment, load an elevated command prompt by right-clicking on Command Prompt and select the Run as administrator option.

2. Type the following:

   netsh interface tcp set global autotuninglevel=disabled

More Information

In certain situations, Windows can automatically overwrite the above user defined setting. To enforce the user-defined autotuning level, you can run the following netsh command from an elevated command prompt:

netsh interface tcp set heuristics disabled
