I have an A record called auto discover in my DNS now if I want to create a SRV record there is no option in the services dropdown box to choose autodiscover so I am unable to create it
Amit KumarCommented:
Please follow this guide and also mentioned stpes

Open the DNS Management MMC snap-in.
Expand Forward Lookup Zones.
Locate and right-click the external DNS zone, and then click Other New Records.
Click Service Location (SRV).
Enter the parameters by using the required values.
Click OK.

Thanks for that but if you read my earlier post that is what I am trying to do.

Whilst creating a SRV account there is no option on the dropdown box to choose autodiscover as a service. Therefore I am unable to create it
Amit KumarCommented:
there will not be you will have to type manually. please post your screen shot

on the other hand, you must have created a A record for pointing to your LB IP or CAS IP.

Because when you are going to create SRV record that will be pointing to a DNS A record whether you go for or it is your choice.

Hope you have full permission on DNS zones.
