Check if this directory d:/pacsone/data/ does exist, and if so, whether the user account PacsOne is running as (by default it's the Windows SYSTEM account) has sufficient permission to create files under that directory.

I can do C-STORE no problem and C-GET also. The only problem that if two workstations access the server for C-GET at the same time and trying to get the same file. The second workstation always gets this error. I checked the rights and even tryed to switch service user to administrator. It almost seems that server opens the file in exclusive mode and that file can't be open for reading unless its done sending for the first connection. Correct me if I'm wrong. Also I don't understand why the error reported with C-STORE and not C_GET.

If you need more info please let me know. Thank you for helping me.

If both C-STORE and C-GET commands are accessing the same file, then one of them WILL get an error, because one command is reading while the other command is writing the same file, and the read/write opearations are mutually exclusive of each other, i.e., you cannot perform both read and write operations on the same file at the same time.

I'm only doing C-GETs and I'm getting this error from C-GET. I just don't understand that in my log the error comes from C-STORE although I didn't perform any C-STORE.

Yes, the Basic Edition of PacsOne Server opens Dicom image files in exclusive mode, so if you have 2 C-GETs pending at the same time, the 2nd one would get an error when PacsOne tries to open the same image file (locked by the previous C-GET operation) and send it via the C-STORE-RQ to the remote peer.

The Premium Edition of PacsOne Server opens the Dicom image files in the non-exclusive Read mode, so the 2 simultaneous C-GET operations on the same file would work fine if you are running the Premium Edition of PacsOne Server.
