I have installed IIS server and our domain name is vhdom.mycomany.com and DNS forward zone is vhdom.mycomany.com. Now I have created a site called https://sharepoint.mydomain.com. I can access the https://sharepoint.mydomain.com from the webserver but not from any other computer from LAN. I was told I need to create host name and point it to sharepoint.mycomany.com with the IP address. However I can not create DNS Host name since our domain is vhdom.mycompany.com
Any thing i can do to fix this issue?
