I get allot of these type of errors in my Event Viewer - event id = 5774 and so I installed the DNS server. One of the errors that I recieve along with about 7 other similar errors (one after the next) is below:
Registration of the DNS record '_ldap._tcp.domain.com. 600 IN SRV 0 100 389 exchange.domain.com.' failed with the following error:
DNS server unable to interpret format.
