you may not have the appropriate permissions to access the item?

I have access to DC through Remote Connection VIA Ipsec VPN

I set map Local drive F: to T:

I access by account call TEST a member of remote connection user

I already set permission of remote connection user to full control at T: Map drive

I can see all folder in T: Drive but when i execute file it say “you may not have the appropriate permissions to access the item”

So I Try to access locally to F: Drive and it can execute properly

Question is– I want to access from T: map drive because of some license

Access through map drive is only way to use this program correctly otherwise i won’t work

ps. Sorry for my English i’m not native
Thank you
