domaindnszones issue?

I do not understand the function of the following DNS structures:
1) DomainDnsZones, _sites, Default-First-Name-Site, _tcp then entries _ldap SRV entries
2) DomainDnsZones, _tcp then entries _ldap SRV entries
3) ForestDnsZones, _sites, Default-First-Name-Site, _tcp then entries _ldap SRV entries
2) ForestDnsZones, _tcp then entries _ldap SRV entries

Are these entries supposed to indicate that these machines are LDAP servers?  Would that mean that they are DCs?

I only have one DC in my enviroment name SQL1, but I see entries for SQL1, Exchange.  There used to be a DC named Exchange but it was demoted with DCPromo.

I know I cannot connect to Exchange on port 389.

Should I delete the entries for Exchange, or is it possible that there are other problems in Ad causing this?

Thanks...

1. Allows a DC to find other servers hosting the DomainDNSZones application partition within the specified site
2. Same, but within the current domain.
3. For finding servers hosting ForestDNSZones within the specified site
4. Once again, same but this time within the domain / forest

Those two areas, DomainDNSZones and ForestDNSZones, are the replication options "All DNS Services in the AD Domain" and "All DNS Servers in the AD Forest" when you look at the properties for a zone in the DNS Management Console.

> Should I delete the entries for Exchange

Yes, if it isn't a DC. Although it's perhaps worth noting that if it was an Exchange Server when it was demoted the action isn't supported and any problems caused by it are unlikely to get much attention.

Normally that kind of housekeeping would be taken care of by the Scavenging process. I guess that isn't enabled?

Anyway, those entries are unlikely to cause a problem because the bits of the PC that use service records are able to deal with a server that doesn't respond.
