We changed mail servers so I need the ip address of our ptr record changed. thanks

At one time, we had our entire office connecting to a Comcast-hosted sharepoint calendar and contact list using Outlook 2007. Now, we can only get one machine to connect using Outlook 2010 - because the 'connect to Outlook' button is simply not listed. The machine that is successful in displaying th

I'm just curious why I can't manage my own PTR records like I can A, CNAME, etc? John can I request a change through you? Thanks! Todd

Hello, I'm hoping this will be the way in which someone finally helps with an ongoing issue. For the last month, we've been experincing phases of extreme latency, resulting in slow internet and even in some cases, interent dropping. I've checked everything on our network end, nothing indicates as a

My business will be moving in 2 weeks; I am having incredibly frustrating problems trying to transfer our phone and internet service to our new location. If I detailed what happened and when, it would come out sounding like a rant, which won't go far towards solving my problems, so...no rant. I've s

Greetings- We are hosting our own email server and are in need of a PTR Record. Any assistance would be greatly appreciated. Thanks!

Hi we need a change to the PTR record for our IP address. We recently changed our domain name and began having issues receiving email from a number of customers. We'd like to return to the original setting until we can correct the problem with our customers. I sent a private message to Comcast_John

Daily Internet Outages for my business is not acceptable. We own a children's learning center. From 3pm on each day, parents entrust their children to us for tutoring - for a month, we have had nothing but trouble with our internet connection. Our phones are tied to the internet, so parents cannot c

I have simple questions about IPv6 subnetting. We have EDI and are given /48 IPv6 addresses but need only one subnet. Currently we assign /48 addresses to all of our devices but I thought I might need to subnet it and assign /64 addresses instead because IPv6's host subnet is /64. My questions are:

I am attempting to add a new user to my Comcast business account, which is current and has mailboxes available (we are not over our email box limit). I have attempted to add the user with his email address (no special characters; just his name), I have followed the password guidelines and received n

Hello, I recently switched to a block of 5 static IPs. I have one major issue: Anywhere from 15 minutes to one hour, the statics assigned to individual servers become inaccessible from outside the gateway. Behind the gateway, everything is fine. The servers are still able to access Internet resource

Hey guys, We're experiencing problems contacting our email server (dreamhost.com). We contacted the webhost, and they asked us to do a trace route. Turns out something is happening at twtelecom.net, and asked us to contact our ISP. We're currently running Comcast Business 50. Can anyone help? Thanks

I was just told by Comcast Support that although I have a static /56 IPv6 assignment on this website (at https://business.comcast.com/myaccount/Secure/ManageServices/Internet/ViewStaticIPSettings/) that goes along with my /29 IPv4 assignment, they can't assign it to my modem: Amara: I did take a loo

All my employees can no longer access the exchange server through comcast from their personal computers. All of us can access the internet, and the internet version of Outlook through the comcast portal. All of us can retrieve e-mail through home computers and hand-helds through the comcast portal.

I have tried several times over the past couple of weeks to get this to work; however, on one of the domains I am attempting to transfer it just gets stuck at step 2. Change the CNAME alias. My other domain tranfer worked just fine. I have tried redoing this several times and then waiting a couple o
