NNTP on ISA Server

 
Hi all,
 
How can i configure my ISA Server to allow NNTP.  I have done the
following config changes on the server. Even after doing the same, not
able to connect, its giving me the error code 800ccc0e
 
A. To enable clients to access news servers (Network News Transfer
Protocol--NNTP), POP3, and SMTP, you need to create custom filters with
the following details: 

                NNTP--Custom, Both, Local Fixed Port 119, Remote Fixed
Port 119 

                POP3--Custom, Both, Local Fixed Port 110, Remote Fixed
Port 110 

                SMTP--Custom, Both, Local Fixed Port 25, Remote Fixed
Port 25 

For example, to create an NNTP filter, perform the following steps: 

                Start the ISA Server administration tool (Start,
Programs, Microsoft ISA Server, ISA Administration Tool). 

                Expand Array, Server, Access Policy, IP Packet Filters. 

                Click Create Packet Filter. 

                Enter a packet filter name (e.g., NNTP Filter), and
click Next. 

                Select the server, and click Next. 

                Select "Allow packet transmission," and click Next. 

                Select a type of Custom, and click Next. 

                Select 

                                IP protocol--TCP 

                                Direction--Both 

                                Local fixed port--119 

                                Remote fixed port--119 

                Click Next. 

                Select the IP address to apply the filter to, and click
Next. 

                Select "All remote computers" for "IP packet filter to
apply to," and click Next. 

                Click Finish. 

The above method is manually creating an IP packet filter to cater for
the protocols however ISA can also dynamically create these if you
instead create a Protocol Rule:

                Start the Internet Security and Acceleration Server
administration tool (Start - Programs - Microsoft ISA Server - ISA
Administration Tool) 

                Expand the Array - Server - Access Policy - Protocol
Rules 

                Create a new protocol rule or open an existing one 

                Select the Protocol tab 

                Select the SMTP (client), NNTP and POP3 protocols 

                Click OK 

This would be the preferred method and is easier. If you're running one
of those services directly on your ISA server, then IP Packet Filters
may have to be defined.

 

Even after this, i'm not able to connect to the NNTP server. Can anyone
pls help me out in configuring the same and i have attached the error
which i get from the client computers when trying to connect to the nntp
server.
