Shared / Exclusive IP, 2 Domains

[dbgrebey]

I have 2 domains sharing the same IP(s).

www.domain1.com & www.domain2.com

When I type www.domain2.com it shows domain2 in the address bar, but actually displays domain1 information.

What is the cause of this? Suggestions?

Thanks,
DBG

More information...

Site Preview on Domain2 shows domain2 information, not Domain1.

--

I've doubled checked my registrar setttings: ns1.domain2.com, ns2.domain2.com

--

Also, when I created domain2 originally, I had my server IP set as exclusive for domain1. I have since changed this to shared with no result.

Additionally,
under server preferences, my server is named: servername.domain1.com--would this have anything to do with it?
