545	Mapserv startup crash on Win Server 2016	TC Haddad	Jeff McKenna	"Mapserv.exe in MS4W 5.2 unfortunately seems to crash on startup on Windows Server 2016 (which admittedly is close to EOL in 2027). 

The final MS4W 5.2 install startup page will show ""Internal Server Error"" in place of the main OpenLayers map, and any click to view the demo WMS, WFS, etc. will also result in a 500 server error. 

Apache Log and Error Log show the following:

""GET /cgi-bin/mapserv.exe?map=/ms4w/apps/local-demo/local.map&MODE=browse&TEMPLATE=openlayers&LAYERS=all HTTP/1.1"" 500 570

and

[client 127.0.0.1:49757] End of script output before headers: mapserv.exe


Other relevant findings to date from command line testing:

Test with map2img SUCCEEDS:
map2img -m ""D:\www\tests\test.map"" -o test.png

Test with mapserv FAILS:
mapserv.exe ""QUERY_STRING=map=D:\www\tests\test.map&mode=map""

Error message produced from this failed test is:
""The application was unable to start correctly (0x000a200)""

Going back in the release history shows that the Windows Server 2016 will successfully run the MS4W 5.2 Beta 1, and that the incompatibility with this OS arose in the betas and release candidates that followed.
