When you use any one of the Active Directory discovery methods on a Microsoft Systems Management Server (SMS) 2003 site, you may experience any or all the following conditions:

•	The SMS Executive service stops responding The subcomponents of the SMS Executive service stop updating their respective log files. Task Manager shows that the SMSExec.exe process is using large amounts of physical and virtual memory. The following entry appears in the log of SMS components, such as Discovery Data Manager or Collection Evaluator, that connect to the SQL server: *** [0][Microsoft][ODBC SQL Server Driver]Memory allocation failure *** [0][Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_DBC failed *** Failed to connect to the SQL Server. Performance may be slow for other programs and for other processes that run on the SMS site server computer. Note SMS log files indicate that Active Directory discovery methods stop responding for long periods of time when large Active Directory containers are scanned. If other SMS components continue to log activity or to process data regularly, you are not experiencing the problem that is described in this article.
•	An access violation error occurs in the SMS Executive component The crash.log file references one of the following discovery components: • SMS_AD_SYSTEM_DISCOVERY_AGENT • SMS_AD_SYSTEM_GROUP_DISCOVERY_AGENT • SMS_AD_USER_DISCOVERY_AGENT However, the computer frequently does not have the system resources to generate a complete log.
•	The HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Inbox Source\Inbox Definitions\0 registry subkey no longer references Site Control Manager. Instead, the Inbox Name and Relative Path entries reference either Discovery Data Manager or Collection Evaluator. These components log the following entry in the respective log files: Createded inbox def 0 Note In this error message, the word "Createded" is a misspelling for the word "Created."

This problem occurs because of memory leaks that are caused by the ADSource.dll file. All three Active Directory discovery methods share this file. The leaks occur most frequently in networks with many computers, and when you use multiple Active Directory discovery methods at the same time.
