I can't opt for "same as publisher folder path" for the server path in the server manager. When I do, it says "directory path not valid. Cannot access this storage location (free translation!)" upon saving.
ESRI says: "Use this scenario (same folder), if you want to avoid having a copy of the data placed on one of the ArcGIS Server machines..." https://enterprise.arcgis.com/en/server/latest/manage-data/windows/overview-register-data-with-arcgis-server.htm#ESRI_SECTION2_781E94B0D808448EBC8CB920E2A6C133
and "If the data does not reside on the ArcGIS Server machine and you use a local Windows account as the ArcGIS Server account, you must create an identical local account (having the same username and password) on the machine that hosts the data. Next, you must grant that local account access to the folders containing the source file. As long as the local accounts on the machine with data and the ArcGIS Server machine are identical, the ArcGIS Server machine can access the data." https://bkggis-tl1.bkg/hosting/help/en/server/11.1/manage-data/windows/making-your-data-accessible-to-arcgis-server.htm#ESRI_SECTION2_5AA7B6E854A341C986B1C2344D7CE9B3
Our IT-Administrator finds this very strange, is it really necessary to create this identical account?

\\lsv649\d:\fileshare-- that's like a mash up of a local and UNC path in one. – KHibma Jun 01 '23 at 13:52d:\myData), then you put that path into your publisher part on the data store. And assuming the Server references the data from UNC (\\lsv649\myData), then match that path to the 2nd part in your data store entry. OR -- during analyze, let the analyzer help you make the data store entry; it should create the appropriate one. – KHibma Jun 05 '23 at 14:14
