FsRtlIsNameInExpression and periods
I ran into a situation where it looked like FsRtlIsNameInExpression was
returning a failure to match when fed these strings:

"*\DOCUME*\*\APPLIC*\*\INSTANCE.DAT"

and

"c:\documents and settings\all users\application
data\{ac7c8e98-ee82-41f7-a85a-2416429a74d3}\instance.dat"

(sans the quotes, of course). The comparison was performed case insensitive
and no upper case pointer was supplied. When the period in the INSTANCE.DAT
was replaced with a question mark then the comparison returned TRUE.

So, my question is this – are period litterals verbotten in the pattern
string?
