Change the canonical name alias
Sign in to your other hosting provider's DNS management page. Enter the following canonical name alias:

Target value: manitowoctransport.comcastbiz.net
The record appears to be in place as per DNSGOODIES.COM:
DNS Records: yytll.manitowoctransport.com
And here are the results for the main domain of manitowoctransport.com:
DNS Records: manitowoctransport.com
