How to check SRV records by using ‘nslookup’

Even though the nslookup is very familiar to lot people its a so confusing tool to always Yesterday I had spent lot of time to see whether the srv record which i have created for Lync 2010 is correct or not.

Oops! I didn't mention why I wanted to verify from the client side, I did setup lync 2010 for my client but auto-login for the client was not working. When setup the client to use the server name manually it worked. You all know that, when client starts it always search for _sipinternaltls SRV records its configured to auto-login.

Lets come back to the point how we can check SRV records from nslookup, here is the steps.

1. Open cmd and type nslookup and press enter key
2. Inside nalookup type ‘set type=all’ and press enter.
   
3. Type ‘_sipinternal._tcp.domainname.com’ and press enter
   
4. You will be able to see the SRV record details of _sipinternaltls record. The same way can be followed for any other records like _ladp.
