Hello Kurt,
If you have open the ports as you have described on your SAS Management Console, there should not be a problem. Are you sure you are having problems on network ports?
First, I would check the EG logging, probably it will provide some additional information.
Secondly, if it is not giving you relevant information (it could be), you can confirm or discard the ports options by running a network tool on the EG pc. Your network guys sure will have something available and it should be easy for them.
Besides this, I can also imagine that, if there is a problem on network communications, it might happen on the server side, on the firewall, or even on the client side. If it is a local pc, on that one, and if you are on a virtualised client, such as Citrix, on the citrix server or firewall where SAS clients are installed.
