Hi,

I have an issue.

From one Widows server only I cannot map a drive to a share on a remote Windows server in the same subnet using the computer name. Although It was working yesterday.  But I can map it using the IP address. Also pinging is working using the DNS name or IP address.

Also I can map to other windows servers shared folders from the above server in the same subnet.

From other Windows servers in the same  I can do it with no problems.

Are using the full DNS name (server.domain.local) for mapping?

Try with the (NetBIOS) name only, like \\server. There might be an issue with the "old style" server name entry.

Since most servers have networking statically assigned verify you network settings especially that the DNS server is the domain's DNS server and not public.  If correct run as admin a command prompt and clear the systems DNS cache using IPCONFIG /FLUSHDNS.  Does a tracert by server name work? does a pathping to the server work?  Are you getting a path error or access denied error?   Are you mapping from windows file explorer or Command prompt? in services make sure the DNS client is running something may have crashed it.

I did All that already.

Basically I can ping the a remote server name but I cannot map a drive to it. Other remote servers from this server I can ping as well as map.

From other computers I can map to the same server with no issues. with no issue.

So the issue is I can ping but cannot map using the same computer name.

We have only one subnet.

Tracert by server name works OK.

I tried using Net USE or from windows explorer, but I cannot map. BUT If I use IP address it works OK.  PINGING by name is fine.

I can also RDP into that server using server name but cannot map a drive.

Check the following outputs for the server name after having tried net use:
  nbtstat -c
  nbtstat -s
  nbtstat -r
  ipconfig /displaydns

It might be an issue with NetBIOS.
Does the remote server has only one NIC (Network Interface Card) ?
And does it only have 1 IP-address configured ?
If the remote server has more NICs than only one 1 NIC NetBIOS should be enabled.

It can also be related to Strict Name Checking or Loopback check.
Does the DNS name corresponds with the "Full computer name" of the remote computer (Control Panel |System) ?

Thanks for the info. Hopefully the problem won't come back after the server is running for some time.
