Can ping NAS by ip and hostname in Windows 10 console, but not find by ip or hostname in Windows explorer

I have set up a new PC with Windows 10. Now I want to access two local NAS drives but can’t connect to them. With my old PC and all coworkers pcs everything is fine. There is no special access restriction. I also can’t see them in the network overview. I am in the same network group and use the same credentials as on my old pc. Weird is that I can connect to our servers harddrive which is no NAS and its within the same network as the NAS.

I can ping it in the console via hostname and ip address but when i try to access it in windows via the explorer it can’t be found. I added the ip to the local hosts file, but it didn’t solved the problem:

192.168.1.5 NASDAILY

What i found out so far:

ping NASDAILY -n 1 // Is working
ping -6 NASDAILY -n 1 // Not working

On the command “ipconfig /displaydns” i get this:

nasdaily

I turned off the pc several times, reset the network connection, turned off firewall, turned of ipv6, nothing helped so far.
