Theresa, I think the problem is that you are restricting the local computer to being the ISA server's external IP address. Does it work if you remove that restriction? Regards, Nick P.S.

Since starting up our ISA server our users can no longer connect. According to IHS we should only have to enable a TCP filter both directions for port 4000 and list only their server's IP address for the remote host access. I have setup a new IP packet filter for TCP fixed port 4000 for both internal and remote computers enabling both directions and listing the ISA server's external address for the local computer and the IHS server for the remote host. I then stopped and restarted the services. But we are getting a connection timeout error. IHS says this error is due to the connection being refused as the firewall is not passing the packets. Has anyone out there worked with Haystack client software? If so, how did you resolve this problem? Thanks for any and all suggestions.
