SYMPTOMS

After you run the Dcpromo.exe tool to install the first Microsoft Windows Server 2003 computer in a domain, and then you restart the computer, you may receive Lightweight Directory Access Protocol (LDAP) bind errors.

When you run the Dcdiag utility on the computer, you may receive the following error message:

LDAP search failed with error 55.
The specified network resource or device is no longer available.

When you run the Netdiag.exe diagnostic utility on the computer, you may receive the following error message:

Cannot do un-authenticated ldap_search to 'ServerName.DomainName.com': Unavailable.
[WARNING] Failed to query SPN registration on DC 'ServerName.DomainName.com'.

Additionally, the following events may be logged in the system event log:

Event Type: Error

The Intersite Messaging service could not read the intersite transport objects from Active Directory. As a result, the Intersite Messaging service has stopped. The Knowledge Consistency Checker (KCC) will be unable to calculate intersite topology without this service. User Action Verify that LDAP queries function properly on this machine. Restart the Intersite Messaging service to continue intersite communication. Additional Data Error value: 58 The specified server cannot perform the requested operation.

Event Type: Error
Event Source: NTDS LDAP

Event ID: 2046
Date: 12/8/2003
Time: 3:34:15 PM
User: N/A
Computer: Server Name
All of Active Directory's LDAP send queues are full. This can be caused by clients that continue to send requests faster than they are processing the results. In order to prevent the server from becoming unresponsive as a result of this condition Active Directory has closed number connections that are not bound as Administrators. Active Directory will continue to close connections until enough send queue space has been recovered to operate normally.

Event Type: Error
Event Source: NTDS KCC
Event Category: LDAP Interface
Event ID: 1312
Date: 12/8/2003
Time: 3:34:15 PM
User: N/A
Computer: Server Name
A call to the Intersite Messaging service that specifies the following transport failed. Transport: CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=Domain Name,DC=com As a result, the Knowledge Consistency Checker (KCC) cannot configure a correct intersite replication topology. User Action Verify that the Intersite Messaging service is running.

If you increase the LDAP Interface NTDS diagnostics to 5, the following event may be logged in the Directory Services event log:

Event Type: Warning

CAUSE

This problem may occur if the value of the MaxReceiveBuffer attribute in the LDAP policy is greater than 10737418. To determine the value of the MaxReceiveBuffer attribute in the LDAP policy, follow these steps:

Click Start, click Run, type ntdsutil, and then click OK.
At the Ntdsutil prompt, type ldap policies, and then press ENTER.
At the LDAP policy prompt, type connections, and then press ENTER.
At the server connections prompt, type connect to server ServerName, and then press ENTER.
At the server connections prompt, type quit, and then press ENTER.
At the LDAP policy prompt, type show values, and then press ENTER.
Make sure that the MaxReceiveBuffer attribute is set to the default value of 10485760. If the value is greater than 10737418, follow the steps that are in the Workaround section to change the MaxReceiveBuffer attribute to the default value of 10485760.
At the LDAP policy prompt, type quit, and then press ENTER.
