I am trying to diagnose the cause. The ActiveX ActiveX control has a much slower loading time on some computers than others, and I found (using ProcMon) that on machines that load the control slowly, the browser seems to be spending a lot of time doing something with this file.
In the slow process, I see event groups (4-8) in the above format, which take about 200 ms to complete:
6:02:17.333 CreateFile C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\index3a0.dat NAME NOT FOUND
6:02:17.364 CreateFile C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\index3a0.dat NAME NOT FOUND
6:02:17.396 CreateFile C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\index3a0.dat NAME NOT FOUND
6:02:17.427 CreateFile C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\index3a0.dat NAME NOT FOUND
However, in a similar route obtained on a machine where control is quickly controlled, I see only one line with the result SUCCESS.
What is this file?
