EV Locator Task Path does not exist

Hello together,

a customer is facing a strange behaviour. In Locator Task settings he includes search paths. (H:\PST_Userfiles_MIGRATION)
After the processing the PSTLocTask report and dtrace are showing the following:

Search behavior for computer Computer01 is to search included folders only and skip excluded folders
Skipping Path \\Computer01\D$\PST-Userfiles_MIGRATION as it does not exist on Computer Computer01

In the sql table "PSTLocatorTask" you can only see the included search path H:\PST_Userfiles_MIGRATION.There are no shares on the ev server like D$\PST-Userfiles_MIGRATION. The folder only exists on share H:\

Where are the references to the D$ share?

Thanks in advance.
