DNS question - adding a host without a FQDN
I have to add our web filtering device's IP address to all of our workstations. I added a host so I can contact "webfilter.domain.company.com" but there are times when it tries to just access the device with just using the name "webfilter" without the FQDN. I can get it working on by adding it to the hosts file on each workstation with no problem, but we have about 3,000 workstations across multiple forests. It would be much easier if I can just add it to the DNS server at each location.Basically I want the name "webfilter" to resolve to the correct IP without having to use the FQDN. Basically I want the name "webfilter" to resolve to the correct IP without having to use the FQDN. Is this possible? Your advice would be greatly appreciated.

Hello, That depends of the used DNS suffixes: http://technet.microsoft.com/en-us/library/cc754152.aspx You can add a webfilter A record with the wanted IP address in your domain.company.com domain. If this is an AD-Integrated zone then it will be replicated to other DC / DNS servers. If this is not an AD-integrated zone and you have a secondary zone for it then it will be transferred at the next DNS zones transfer.

Hiya, Create a CNAME record in your company.com DNS zone as follows: Alias Name: webfilter FQDN: webfilter.domain.company.com And in your domain.company.com zone you create a new ANAME record. Name: webfilter IP: <IP of your webfilter server> Not sure if its best practise, but it should get the job done with minimum effort.

Hi KG Tech, If you are using Windows Server 2008 R2 you could use a GlobalNames Zone within DNS. This addresses your issue. http://technet.microsoft.com/en-us/library/cc731744.aspx
