Error "No Network Provider accepted the given the network path"

Hi all,

There is an error: "No Network Provider accepted the given the network path" when I deploy SEP client 11.0.7200 to Windows Server 2000 SP4.

I checked 11.0.7200 support Windows 2000.

And I readed below article.

•disabled Simple File Sharing in Windows 2000
But I don't know how to check and disable my firewall in Windows 2000...

And fail to telnet the client using command "telnet <IP> 139"...

How can I make TCP ports 139 and 445 and UDP ports 137 and 138 are listening on the target computer...??
