The format of the specified computer name is invalid

I have a user that is getting the following error when trying to connect to our file server: Microsoft Windows Network: The format of the specified computer name is invalid.

This user works from a remote office and is conttected via a hardware to hardware VPN. I can ping the file server by both the IP address and the file share server name from the users computer. But when I try and go to Run and type \\ServerName\Share or \\IPAddress\Share I get the same error.

I'm not sure what is going on. Any suggestions would be great.

Thank you in advance.

What is the servername you are trying to reach?

Assuming the servername is less than 15 characters, and doesn't have any forbidden characters.

Are any ports filtered by the VPN?  Any router ACLs filtering RPC or Samba ports?

You include DNS as a potential trouble area.  I don't see anything in the problem description to indicate that?  (When you ping the file share server, does it indicate that it has resolved the correct IP?)

Thats where I was heading regarding the servername. Could be a DNS/ WINS issue but would need more information

Yes the files server (really a NAS) name resolves when I use it to ping, as well as the IP address.

I am not filtering any port on the VPN since it is a dedicated hardware to hardware VPN.

This just started happening...I was told by the user that they were able to access the file share as of yesterday and nothing has changed as far as I can tell.

I think I'm going to try and reboot the file server and see if that changes anything.

I rebooted the file server (NAS) and that has seemed to resolve the issue.

Thanks.
