CAUSE
These issues may occur if a domain controller in the Microsoft Windows domain has been removed. When a domain controller is removed from a Windows domain, all the symptoms that are described in the &quot;Symptoms&quot; section occur if the following conditions are true:
 * Microsoft Exchange had been using the domain controller that has been removed as its global catalog referral server. There is still a reference to the domain controller in Domain Name System (DNS). Specifically, there is a host record that still points to the domain controller that was removed.
 * The domain controller that has been removed was configured as an alternative DNS server in the properties of TCP/IP on all the domain controllers.
 * DSProxy detects a problem while obtaining the list of global catalog servers from DSAccess. DSProxy triggers a failure, and the clients cannot connect to the Exchange server.



RESOLUTION
To resolve these issues, use one or more of the follow methods.

Method 1: Update the DNS information
You must update the DNS information on your Exchange server by removing the host record that is pointing to the domain controller that was removed. To do this, follow these steps:  Click Start, click Run, type cmd in the Open box, and then click OK.</li> At the command prompt, type the following commands, and then press ENTER after each command:

ipconfig /flushdns

ipconfig /registerdns

</li></ol>

This procedure updates the DNS information. Exchange will then link with a domain controller that is online.

Method 2: Verify that the DNS server contains the record to the global catalog server
You must verify that the DNS server contains the record to the global catalog server. To do this, first follow these steps on the DNS server computer:
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click DNS.
 * 2) Expand Forward Lookup Zones, expand , and then expand the global catalog.
 * 3) In the right pane, locate the Host or the A record for the global catalog, and then note the IP address.

Next, follow these steps on the computer that is running Exchange Server: <ol> Click Start, click Run, type cmd in the Open box, and then click OK.</li> At the command prompt, type the following command, and then press ENTER:

ipconfig /all

</li> Note the IP address that is listed for the DNS servers. Make sure that the IP address of the DNS server matches the IP address of the Host or the A record for the global catalog that you noted in the Forward Lookup Zones on the DNS server.</li> If an external DNS server is listed, follow these steps to remove the external DNS server: <ol style="list-style-type: lower-alpha;"> Right-click My Network Places, and then click Properties.</li> Right-click Local Area Connection, and then click Properties.</li> Click Internet Protocol (TCP/IP), and then click Properties.</li> In the Use the following DNS server addresses area, remove the IP address of the external DNS server.</li> Click OK two times, and then close Network and Dial-up Connections.</li></ol> </li> At the command prompt, type the following commands, and then press ENTER after each command:

ipconfig /flushdns

ipconfig /registerdns

</li></ol>

Method 3: Configure the DNS server to locate its domain global catalog servers
Either a Standard Primary DNS zone or an Active Directory DNS zone must contain the _msdcs, the _sites, the _tcp, and the _udp domain records. To verify the DNS settings, follow these steps: <ol> On the DNS server, click Start, point to Programs, point to Administrative Tools, and then click DNS.</li> Expand  , expand Forward Lookup Zones, and then expand  . The following four folders must appear under  :  _msdcs</li> _sites</li> <li>_tcp</li> <li>_udp</li></ul> </li> <li>If the folders are not listed, correct the DNS settings. To do this, follow these steps: <ol style="list-style-type: lower-alpha;"> <li>Right-click the  , and then click Properties.</li> <li>Click the General tab, and then click Yes in the Allow Dynamics Updates list.</li> <li>On the DNS server, click Start, point to Programs, right-click My Network Places, and then click Properties.</li> <li>Right-click Local Area Connection, click Properties, click Internet Protocol (TCP/IP), and then click Properties.</li> <li>In the Internet Protocol (TCP/IP) Properties window, verify that the Use the following DNS Server addresses check box is selected and that a valid DNS IP address appears in the Preferred IP Address box.

Note The IP Address must correspond to the DNS server IP address in the domain. You must use an IP address that does not change for the server. Do not use the IP address of your Internet service provider (ISP).</li> <li>Click Advanced, and then click the DNS tab.</li> <li>Verify that your domain name appears in the DNS suffix for this connection box, and make sure that the Register this connection’s addresses in DNS and the Use this connection’s DNS suffix in DNS registration check boxes are selected for this DNS.</li> <li>Click OK three times, and then close Network and Dial-up Connections.</li></ol> </li></ol>
