MDM Display Limit of 500 Items Under the MMC (235132)

SYMPTOMS

The Site Server Membership Directory Manager (MDM) plugin for the MMC is hardcode-limited to only display 500 users. This limitation makes it difficult to administer a large Membership directory without writing custom ASP code for administering user accounts. Filtering may prove to be difficult as well, particularly in the anonymous users container if many objects are present. A lot of work would be involved in trying to come up with useful filters to get all the users.

CAUSE

There is a display limit of 500 by default. This can be modified as noted in the "Workaround" section. However, the modification will not be recognized by the MDM since the new limit configured in the registry was not being loaded and utilized.

RESOLUTION

To resolve this problem, obtain the latest service pack for Site Server 3.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

NOTE: In order to utilize this option, the hotfix must be installed. As documented in the Site Server HTML Help, the following registry RegDword value can be added in order to display a larger number of objects (ie: 999).

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Site Server\3.0\P**M\MDM\DisplayLimit
NOTE: ** should be an ampersand but Kbtools rejects the symbol

1000 (DEC)/3e8 (HEX),

Set the properties on the corresponding LDAP instance where "Max results set:" = 999, one LESS than the "DisplayLimit" in HKEY_LOCAL_MACHINE you should see 999 objects.

MORE INFORMATION

It is possible to increase the number beyond 1000. However, this will result in an increase in the MMC.exe working set size and results in large amounts of data delivered to the client. This may cause delays and potential timeouts in slow network configurations. All objects are sent to the client for display. Exhaustive testing has not been performed with large configurations.
