This is ridiculous

I had the same problem yesterday after getting exchange mail set up for our domain, a call to customer service reset the password and I was able to log in. I also find the URL matters, I have to use http://businessclass.comcast.net for one of our email names, http://comcast.com/myaccount for another. Yet both are associated with the same business account.

I haven't been able to log in to any comcast services with that account. I was able to manually reset the password today with this account for the first time. For a month now, it has failed with a non-descriptive error every time I have attempted to do it. Magically, as soon as I posted this complaint, I was able to go back and reset it and it worked. 

I have had a number of communications with CS about this, as well as being unable to use the SiteBuilder tool. 

Hi rw_hardin.  I apologize for the continued problems you've encontered while attempting to resolve this issue.  I have re-engaged the Business Service Center in order resolve this issue.

Thank You

I experienced the same thing. Apparently the first-tier support folks use different tools to access our accounts, and do not have actual internet access with an actual browser, so they don't know what we're talking about. It's a bit frustrating for both the poor support person and customer.

Well, luckily, the login issues are fixed. However, I still do not have access to Site Builder, which was the original issue I was seeking support for. Apparently, "fixing" that issue led to the login issues. Or something. I don't know.
