I used domain mapping here for a couple of sites on this multisite installed on a subdomain install on http://www.corriedmarketing.co.uk.
The root site is corriedmarketing.co.uk/marketingusuite and the subsites in quesiton are scottishslimmers and idealwindows.
The main issue I have to address is that we set up offers.idealwindowsandconservatories.co.uk with an aname record pointing to the corriedmarketing.co.uk ip address, then mapped it into http://www.corriedmarketing.co.uk/marketingsuite/idealwindows, so that http://offers.idealwindowsandconservatories.co.uk/marketingsuite works from there..
The issue is that if you type in offers.idealwindowsandconservatories.com it resolves to the main http://www.corriedmarketing.co.uk site.. because of the aname mapping
Is there any way to get this to not do that... the customer is not happy...
We had to do this domain mapping on the /marketingsuite multisite as the main corriedmarketing.co.uk site is not a WordPress site and the customer site was not WordPress either...
I have given you access so you can have a look.
We are using these as landing pages for advertising campaigns and only the /marketingsuite version of the customer domain is used in banner ad links but they are still not happy that the offers.idealwindowsandconservatories.com maps back to the agency site...
