AIMS 2017 - new error message

After updating from AIMS 2013 to AIMS 2017 no raster images were shown. Any preview in Studio triggered the following error message in the log file:

This message was new to me and hadn't occurred with AIMS 2013.

Also, "Testing connection" always returned "OK" for our raster file data source. The raster file data source uses an ALIAS which points to a shared network drive.

Problem was, that AIMS 2017 was running under local user account. In order to access the network drive AIMS service needs to run under different user account. 

AIMS 2017, SP1

MapGuide Alias - UNC

I just tried to set up an alias for MapGuide / Infrastructure Mapserver 2013. I tried a few different UNC path options (for instance with concluding backslash) but no - it just didn't work. Finally I found my mistake - just the UNC path for the share is not sufficient. I had to add a folder to get it to work.

Does not work:

\\bla.net\fachappli$\MG_DATEN  (>> just the share)

Does work:

\\bla.net\fachappli$\MG_DATEN\Raster (share and subfolder)
