I'll think of a clever title one day. Today's not that day. Tomorrow's not looking good either.

I love when I find a helpful tool on download.microsoft.com....

There are few tools I would say that I use *every* day. This is one of them.
ERR.exe is a tool I use all the time to look up error codes. When someone
gives me an error code, the first thing I do is toss it in err so I know
what I'm looking at. For example:

C:\tools>err 8402
# for decimal 8402 / hex 0x20d2 :
  SQL_8402_severity_16                                          sql_err
# The data type of the '%s' must be '%s'. '%s' is not
# allowed.
  ERROR_DS_CANT_CACHE_CLASS                                     winerror.h
# The class could not be cached.
# 2 matches found for "8402"

Note that it doesn't just look in a single .h....it looks in  many at once! And not just Windows either. Very handy.

Happy ERRing!
