SiSoftware Sandra - The Diagnostic Tool, Q & A - Network/LAN Bandwidth Benchmark

This document provides some frequently asked questions about Sandra. Please read the Help File as well!

Q: I get Packet too large for Network/Host error
A: Sandra uses 64Kb blocks to test the transfer rate. Some interfaces do not support packets this large, but only smaller packets. You can try the following:

• Try the latest network drivers from the network card manufacturer. In most cases the built-in Windows drivers are scaled-down versions.
• Check the driver settings - there may be a setting to allow large packet fragmentation or change max. packet size.
• If you've used a modem speed booster make sure you've changed only the dial-up settings and not the LAN settings too. Go back to the defaults and/or clear all the settings from the registry.
• Use a decent network adapter, e.g. Intel/3Com/HP/Compaq/etc with an internal buffer.
• As a last resort, try a clean install of Windows.

Q: I get Cannot get IP address of host error
A: Go to a console and try to ping the host by name. If you cannot, make sure DNS/WINS is correctly set up, otherwise enter the host names and their IP addresses in the HOSTS file.

Q: Why are there no workgroups/domains visible?
A: Check that you've set your computer to be part of a workgroup or the correct domain and that you're running the Microsoft Networks Client.

Q: Why are there no computers on the domain/workgroup?
A: Check that the network settings are correct. Try to connect to some of the computers you know should be on the network or ping them.

Q: Why is my computer not listed in the domain/workgroup?
A: There would be no point benchmarking the local interface, thus your computer is not shown if the workgroup/domain it is in is selected.
