The semaphore timeout period has expired

I have a step which copies files from a network location to another network location (size approx 100 Mb)
The copy step fails after approx 1 hour and 30 mins with this message:

2/18/2011 2:50:54 PM: Building project step 1119 - Copy install kits to Sydney Latest folder...
\\hqt\Public\NGKits\10.1.1315.0\ -> \\syd-01\Public\NGKits\NGLatestKits\
Copying: Setup.exe
Error copying file '\\syd-01\Public\NGKits\NGLatestKits\Setup.exe': The semaphore timeout period has expired.
0 file(s) copied
2/18/2011 4:11:11 PM: Step '1119 - Copy install kits to Sydney Latest folder' failed

First thing I do not understand is what is causing this problem.
Second thing –why if the step failed –I still have in the target folder (\\syd-01\Public\NGKits\NGLatestKits) a corrupted version of Setup.exe
Maybe someone could explain ...
Thanks

The Copy Files action calls the Windows CopyFileEx API to copy files, and that is what is returning the error message. It sounds like some sort of network connectivity or DHCP issue.
