In order to write down the password from the file share, for the user from which the 1C service starts, you need:
1) In group policies, allow the user usr1cv82 to log in to the system.
To do this, go to gpedit in Computer Configuration -> Security Settings -> Local Policies -> Assign User Rights -> Deny access to this computer from the network – remove our user
2) Add a user to the Administrators group (lusrmgr.msc)
3) Go under this user and run control userpasswords2, there additionally -> password management -> windows credentials. And here already add passwords to the shares to which the server needs access
4) We remove our user from the group of the administrators and return it to the group policies.
