Invalid Landing Page Domain

[Anonymous]

I'm trying to complete my marketo setup, and IT has informed me they've created by CNAME records for my landing page and email.  Now when I go into admin, it says "Invalid Landing Page Domain" and I also get an error for my email CNAME.  My web developer sent me a screenshot of the records, which matches what I was given in my IT configuration protocols.  What's my next step to troubleshooting this?

Thanks Josh - it's been about 2 weeks.  I've got them checking to make sure it was put on the external server and not internal.  Wonder if there are any other reasons for the error?

You may have to wait 2 to 48 hours for the DNS record to propagate across the world. Until that happens, marketo won't recognize the domain.
