We are setting up a build engine on Windows 2003 (also tried 2008) and are seeing an bad_record_mac HTTP exception that stops the build, but it happens at different points of the process. Most of the time it happens during the initial push of files to the build engine, but each time it is a different file that fails. Rarely (~1 in 7) it actually downloads and start ANT.

Googling showed not much other than tweaking a Broadcom ethernet setting that did not help. Any clues to what a bad_record_mac is and how to get around it much appreciated!

Here is a typical dump:
