Local DNS issues while connected to OpenVPN

I'm using OpenVPN to connect multiple clients to a file server on a remote network. I'm currently able to successfully connect to the network and server. However the issue is the file server's DNS/hostname is not resolving (this is true for all connected devices on this network) even though I'm able to access the file server via IP.

This is my current network:

Server LAN:

Address space: 192.168.0.0/24

Router address: 192.168.0.1 (this is a DNS server)

File server address: 192.168.0.20

File server host name: FS1

Client LAN:

Address space: 192.168.150.0/24

Router address: 192.168.150.1 (this is a DNS server)

VPN:

Address space: 10.10.10.0/24

OpenVPN server address: 10.10.10.1

This is the OpenVPN options set on the server.

--port 1194
--tls-server
--comp-lzo yes
--persist-key
--persist-tun
--keepalive 10 120
--user nobody
--group nogroup

This is my config file for clients.

 client
 dev tun
 proto udp
 dev-node NETGEAR-VPN
 remote 192.168.0.1 1194
 resolv-retry infinite
 nobind
 persist-key
 persist-tun
 ca cacert.pem
 cert client.pem
 key clientd.key
 user nobody
 group nogroup
 cipher AES-256-CBC
 auth SHA256
 comp-lzo yes
 verb 3

"Windows cannot access \fs1" is the error I'm getting when I try to connect to the file server from a file explorer via the client network. the error code is 0x80004005 which is a unspecified error. I'm able to ping the DNS server's ip address but not the host name.

My router on the server network is an Ubiquiti edge router, the file server is running win 2012, and my clients are running win 10. all external DNS related traffic seems to be working. Also I have verified that the server's network is successfully resolving host names locally

If I'm missing any other details please inform me thanks and have a great day!
