Cannot rename a file geodatabase on a network drive - How to know what locks it

[MarkMindlin]

Hi,

We try to rename a file geodatabase on a network drive in ArcCatalog

We aware of this article (it did not helped):

Problem: Unable to rename file geodatabases in ArcMap 

We have no *lock files inside, no antivirus installed, ArcGIS Server stopped.

When we try to move *.gdb folder, the error appears

Any help please - at least to know what locks the folder
