DNS issue with SmartConnect

Hello,

We setup SmartConnect with a delegated DNS zone with the NAS as the Name Server, and use CNAME DNS records to reference the old Windows file servers that were replaced. Sometimes pinging the CNAME value does resolve to anything, and there are some time out issues with Windows profile redirection in the VDI environment. Any ideas what would cause this? Could it be a low TTL value for the DNS records? Thanks!

What does CNAME point to ?  Should point to NS record that points to A record that is you SSIP

Actually, it happens even with the delegation name, outside of the CNAME. I think it might be a DNS server issue where the DNS in the parent zone doesn't resolve the delegation correctly.

Re: DNS issue with SmartConnect

In case anyone is interested, it was actually caused by the root DNS servers in our forest not having the correct copy of the delegation. Once we remove the root DNS servers from the DNS server list on the clients, everything work as expected. Thanks everyone for assisting.
