Error creating IIS Virtual Direction on Remote PC

[CMoore]

Hi,

I'm getting an error when creating a virtual directory in IIS on a remote PC. It works ok to create an IIS application on a server on our LAN, but if I try to create the application on a server through the internet, I get the error:

Error in Action (JScript) script code at Line 21, Column 2 (The remote server machine does not exist or is unavailable)

I can ping the machine and I have opened the firewall to this server to allow the following protocols...is there something I am missing? Do I need to set some permissions somewhere?

RPC endpoint mapper
135/tcp, 135/udp
Network basic input/output system (NetBIOS) name service
137/tcp, 137/udp
NetBIOS datagram service
138/udp
