Dan,

Are you supposed to use backslashes in those network redirectors?

Like "\\HP_SERVER\RDRIVE\STREETS\STREETS.BAT"?

I don't normally use that mechanism myself, so I did a little test.  I
compiled the following program:

#include <stdio.h>

int main()

{
    const char *pszFilename = "\\\\gdal\\warmerda\\.cshrc";
    FILE *fp = fopen( pszFilename, "t" );

    if( fp == NULL )
        perror( pszFilename );
    else
        printf( "Success!\n" );
}

When I run it, I get a NULL "fp" from fopen, but there does not seem
to be any error reported by perror().  I'm not sure exactly what to make
of there being no errno value set, but as I get fp back, it does seem that
fopen() does not support this style of network redirector.

I would add that "type \\gdal\warmerda\.cshrc" worked fine for me at the
CMD.EXE prompt.

So, if fopen() does not support these redirectors, then neither will OGR
or most other MapServer components.

Of course, I'm not particularly savvy about win32 type stuff, so I might
be missing something.

Best regards,
