This one is tricky to test. I honestly initially thought this was due
to the new MapServer security settings, but I'm not so sure now.
I can definitely specify the network name for the machine, such as:
LAYER
...
CONNECTIONTYPE OGR
CONNECTION "\\\\name\folder\demo.db"
DATA "places"
...
END
- works fine at the commandline:
map2img -m network.map -o ttt.png -all_debug 3
- I assume the same will apply to GDAL/rasters
- the 4 backslashes are required
Truthfully, I don't use IP addresses for calling my shared folders, here
on MS4W/Windows, so I would need more time to examine this.
I'm sure others here will be able to give feedback, who regularly use
local IPs for their network shares.

In the map file, turning the |DEBUG ON| for LAYER and |DEBUG 5| for MAP,
the ms_error.txt reports the following:

However, placing the tif image in the shape data dir, OpenLayers show
correctly in the browser.
Also, |gdalinfo.exe
//192.168.210.150/some/shared_dir/a_float_type_image.tif
<http://192.168.210.150/some/shared_dir/a_float_type_image.tif>| reports
no error, as well as
|gdal.Open('//192.168.210.150/some/shared_dir/a_float_type_image.tif
<http://192.168.210.150/some/shared_dir/a_float_type_image.tif>')| in
python.
My guess is, somehow, in mapraster.c line: 650, |GDALOpenEx| returned
NULL for paths like
|//192.168.210.150/some/shared_dir/a_float_type_image.tif
<http://192.168.210.150/some/shared_dir/a_float_type_image.tif>|.
