Right now my active directory is failing a dcdiag test. I can find no info online about this error.
When I run dcdiag /test:crossrefvalidation, I get the output:

This cross-ref has a non-standard dNSRoot attribute.
Cross-ref DN:
CN=a3a24d3a-4782-460b-9148-86ac2d86b9ae,CN=Partitions,CN=Configuration,
DC=mydomain,DC=com
nCName attribute (Partition name): DC=t
Bad dNSRoot attribute: dc01.mydomain.com
Check with your network administrator to make sure this dNSRoot
attribute is correct, and if not please change the attribute to the
value below.
dNSRoot should be: t
It appears this partition (DC=t) failed to get completely created.
This cross-ref
(CN=a3a24d3a-4782-460b-9148-86ac2d86b9ae,CN=Partitions,CN=Configurat
ion,DC=mydomain,DC=com)
is dead and should be removed from the Active Directory.

I used LDP from the windows support tools. I searched for the dnsRoot attribute in "cn=partitions,cn=configuration,dc=mydomain,dc=com", with the filter "(&(objectcategory=crossref)(systemFlags:1.2.840.113556.1.4.803:=5))"
I got the result:
***Searching...

It looks like the bad partition has the name of my first domain controller 'ad01.mydomain.com'.
I have googled for a while and have not been able to find any help or documentation about application partitions in Active Directory.
Does anyone have any advice on how to cleanup this partition (or what the partition is for)?
Does anyone know the repercussions for deleting this partition?
