I really have no idea, but I thought I would toss this out there:

[~]$ nslookup brynmawr.edu

Server: 172.19.254.4

Address: 172.19.254.4#53

Non-authoritative answer:

Name: brynmawr.edu

Address: 165.106.1.8

[~]$ nslookup forums.brynmawr.edu

Server: 172.19.254.4

Address: 172.19.254.4#53

Non-authoritative answer:

forums.brynmawr.edu canonical name = blog-serv.brynmawr.edu.

Name: blog-serv.brynmawr.edu

Address: 165.106.1.51

Then I remembered this post:

https://bbpress.org/forums/topic/installation-to-sub-domain-error-400#post-65

If you search these forums for subdomain and wpmu, you might find something useful. I don’t use WPMU or subdomains, so I am just guessing here.
