HOW TO: Modify the MaxQueryDuration Setting for Active Directory Services Interface (291438)

SUMMARY

This article describes how to modify the query policy setting for MaxQueryDuration (maximum query duration). After two minutes, the Active Directory Services Interface (ADSI) queries to Active Directory can stop responding. This behavior can be caused by the MaxQueryDuration setting, which has a default time of two minutes. This value, however, can be changed by using the Ntdsutil.exe utility.
