Problems with IIS

Hello all:

Recently I moved an application developed with metastorage from a LAMP
to a Windows + IIS + PHP + MySQL, and all seems to be work all right
except the compilation of the model.

I got the next error:

Error: could not create the XML cache file directory
"C:\Inetpub\wwwroot\chcrui\Interfaz\front_end\trabajo\Actual\metal\metastorage/work/cache/C/Inetpub/wwwroot/chcrui/Interfaz/front_end/trabajo/Actual/metal/metal/include"

File:
C:\Inetpub\wwwroot\chcrui\Interfaz\front_end\trabajo\Actual\metal\metastorage/work/cache/C/Inetpub/wwwroot/chcrui/Interfaz/front_end/trabajo/Actual/metal/metal/include/php.bindings.cache

Line: 0 
Column: 0 
Byte: 0 

I configured PHP with more than 8mb, I reviewed that directories of
metal, metastorage and projects has enough privilegs and I tried to
compile cms example project, but i got the same error once and again.

I search the whole mails of the list for something similar and read
the FAQS but I did not found something similar.

The problem is that I have never been working with IIS, so any Ideas?

Thanks in advance.
