UNC Paths

You need to step very carefully if you want an IIS application to be
able to access network resources.  Remember that MapServer is running in
the security context of the user configured for that application under
IIS.  By default, this is the IUSR_<machinename> account.  By default,
this account is a LOCAL machine account and has no access to any network
resources, under any name.  This is a security feature to restrict Web
visitors from access to your network.

As a start, you should read and fully understand the document "How to
access network files from IIS applications" from Microsoft:

Subject: [UMN_MAPSERVER-USERS] UNC Paths

Hello,

I've just installed Mapserver on Windows XP and would like to use UNC in
my OGR Connection (e.g. "//HP_SERVER/RDRIVE/STREETS/STREETS.TAB") to
reference the map data rather than use mapped drives (e.g.
"R:/STREETS/STREETS.TAB").
I'm getting the error:

msDrawMap(): Image handling error. Failed to draw layer named 'Water'.
msOGRFileOpen(): OGR error. Open failed for OGR connection
`//HP_SERVER/RDRIVE/STREETS/STREETS.TAB'. File not found or unsupported
format.

What am I doing wrong?
