XADM: Limiting Logons to the Information Store
ID: Q146764
|
The information in this article applies to:
-
Microsoft Exchange Server, versions 4.0, 5.0, 5.5
SUMMARY
Microsoft Exchange administrators can limit the users who are allowed to
logon to the Information Store. This can be useful when you need to perform
maintenance or upgrades to the Microsoft Exchange Server and to keep users
from logging into Exchange.
MORE INFORMATION
To limit allowed users:
- Stop the Information Store Service on the Exchange Server.
- Run Registry Editor (REGEDT32.EXE).
- From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
- Select EDIT, and then ADD VALUE, type "Logon Only As" in the VALUE NAME
box (do not type the quotes but do type the spaces and capitalize as
indicated). Type REG_MULTI_SZ in the Data Type box.
- Choose the OK button. In the Data box, type the Distinguished Names of
those you want to allow to logon to the Information Store on separate
lines and then choose the OK button. For example:
/o=microsoft/ou=apps-wga/cn=recipients/cn=user1
/o=microsoft/ou=apps-wga/cn=recipients/cn=user2 - Choose the OK button.
- Close the registry editor.
- Restart the Information Store Service.
This allows only those entered in the registry parameter to logon to the
store. Users not specified in the registry parameter receive the following
error when they try to connect to the Information Store:
The set of folders could be opened.
The attempt to log on to the Microsoft Exchange Server has failed
NOTES:
- Leaving the registry parameter blank prevents all users from logging
onto the Information Store.
- To allow all users to again logon onto the Information Store the
registry key must be removed. The following steps can be used to remove
the registry key:
- Stop the Information Store Service on the Exchange Server.
- Run Registry Editor (REGEDT32.EXE).
- From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
- Select the "Logon Only As" value in the right pane.
- Select EDIT and then DELETE.
- Close the registry editor.
- Restart the Information Store Service.
