CAUSE

This problem may occur if your Domain Name System (DNS) configuration does not have service location records (SRV records) configured. The problem may occur if all the following conditions exist:

Your DNS configuration does not permit dynamic updates.
You install a global catalog server in the domain, and select the No, I will install and configure DNS myself option during the Dcpromo procedure.
You do not manually configure the service location records (SRV records) in DNS.
You install Exchange Server 2003.

Exchange Server 2003 Setup does not warn you that the DNS configuration is not valid before it continues with the Exchange installation.

WORKAROUND

To resolve this problem, configure DNS to permit automatic updates, and then re-register the server or servers in DNS. To do so:

Start the DNS utility on the Windows 2000-based server.
Expand Forward Lookup Zones, right-click the appropriate forward lookup zone, and then click Properties.
In the Allow dynamic updates? list, click Yes or Only secure updates.

Note The Only secure updates option is only available if the zone type is set to Active Directory-integrated.
Click Apply, and then click OK.
On a domain controller, do one of the following:
- Restart the Net Logon service to force the domain controller to re-register SRV records. To do this, enter the following commands from a command prompt and press ENTER after each command:
  net stop netlogon
  net start netlogon
- Run the netdiag /fix command to verify SRV records. To do this, enter the following command from a command prompt, and then press ENTER:
  netdiag /fix
Re-register other servers in DNS. To do so, enter the following commands from a command prompt on the server that you want to re-register, and then press ENTER after each command.
ipconfig /flushdns ipconfig /registerdns
