[Mapserver-users] OGR unable to access datasource

[Paul Spencer]

I wonder if this could be an IIS issue?  IIS runs as a different user 
normally, and has considerably reduced privileges in order to block up 
potential security issues.  Can you possibly set up Apache and try with 
Apache?  If it works with Apache then we can be sure it is an IIS 
configuration issue and focus on figuring out why it won't work.

The other possibility is that your mapserver does not support VRT, did 
we rule that out yet?
