The Information Store service remains in a starting state in Exchange 2000 Server

When you try to start the Microsoft Exchange Information Store service, you receive the following message:However, the progress indicator does not move to the right side of the Service Control dialog box, and the service never starts.

Additionally, if you run the domain controller diagnostics tool (Dcdiag), and you direct it to the global catalog server by using the dcdiag /s:"fully-qualified domain name of the global catalog server" command, you receive the following output:

This issue may occur if there is no global catalog server available in your domain or in the root domain of your Microsoft Active Directory directory service forest. In this scenario, Microsoft Exchange 2000 Server may discover a global catalog server in another domain and try to use that global catalog server. If Exchange 2000 Server cannot resolve the host name of that global catalog server to an IP address, the Information Store service remains in the starting state and continues to try to contact the global catalog server.

This issue occurs because of a name resolution problem that causes Exchange 2000 Server to try to resolve the host name of the global catalog server by using its short (host) name instead of by using its fully-qualified domain name (FQDN).

To resolve this issue, configure the Domain Name System (DNS) suffix search list on your Exchange computer to include the domain names of all the domains where Exchange 2000 Server requires access to domain controllers. To do this, follow these steps:

1.	On the Exchange computer, right-click My Network Places, and then click Properties.
2.	Right-click the local area connection, and then click Properties.
3.	Double-click Internet Protocol (TCP/IP), and then click Advanced.
4.	Click the DNS tab, and then click Append these DNS suffixes (in order).
5.	Click Add, type the domain suffix of a domain where Exchange 2000 Server requires access to a domain controller, and then click Add. For example, type corp.contoso.com.
6.	When you are finished adding DNS suffixes, click OK, click OK, and then click OK.

To work around this issue, configure WINS servers in your domain, or configure your network to permit broadcast message traffic to reach your domain controllers.
