Comcast tech replaced the router with another Cisco 3939B. Woody checked out the connected devices. Everything looks good.
Helen, this server, went down again this morning. I bounced power to the server but that was not enough. Woody went to the POP and swapped ports with the Power Distribution Unit on the Cisco Gateway router and Helen came back. Bounced the Cisco router and after about 10 minutes everything came up. Waiting for a response from Comcast on the reliability issue.
