Windows Server 2003 - Maximum Number of ACEs per ACL
-
Friday, June 13, 2008 11:49 AMI am a server admin (running Windows Server 2003) and am wondering what the maximum number of Access Control Entries I can have in a single Access Control List might be. Or, if this number is implementation specific, how I might find out what the maximum number is and possibly change that number if need be.
Help in any way is very much appreciated. Thanks in advance,
Mike

Hello,
According to the following KB article, the size of an ACL varies with the number and size of its access control entries (ACEs).
The maximum size of an ACL is 64K, or approximately 1,820 ACEs. However, for performance reasons, the maximum size is not practical.
