Exited with code -1073741819

I was having trouble building my VS2008 solution today due to the following error:

Error 1 The command "copy "C:\SVN\..." "C:\SVN\..." /Y
xcopy "C:\SVN\..." /S "C:\SVN\..." /Y" exited with code -1073741819.

This was occuring in my post build events on one of my project files.

My Solution:

IISRESET

Seems to do the trick :S
