Is MBSchExt.xml a legitimate schema file ?

iis security:

I am writing security policies for IIS 6.0 (Windows 2003 Server) and
noticed that IIS tried to write MBSchExt.xml file. Unfortunately, I
could not look in the file since the IPS software prevented from
writing this file.

I cannot find any information on MBSchExt.xml, is this a legitimate IIS
schema file or just another virus ?

Any thoughts ?

have not seen this before? if you open it via notepad... any hints in the
file?
it could be a temp file or etc. if it's created by IIS services than it
should be legal and clean.

how do you find out about the file?

My IPS blocks IIS to write any non standard file types. Hence IIS was
never allowed to write this MBSchExt.XML file so I dont know what this
file would contain.

I am wondering if I should let IIS write this file, sounds like a
legitimate filename, but again best viruses use legit filenames :(
