We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 7.0 running on Microsoft Windows Server 2008. IIS 7.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:
Internet Information Server (IIS) has a default delay of 15 minutes beforeusers tokens are updated. For example, if you change the password on a useraccount, you will be able to connect to the server with both the oldpassword and the new password.
For performance reasons, user tokens are cached by IIS and updated at 15minute intervals.
The token cache can be refreshed manually by stopping and restarting ALL ofthe IIS services (Gopher, FTP, and WWW). For performance reasons, this isthe preferred method if updates are infrequent.
The default interval for the token cache can also be changed in theMicrosoft Windows registry.
WARNING: Using Registry Editor incorrectly can cause serious, systemwide problems that may require you to reinstall Windows to correct them.Microsoft cannot guarantee that any problems resulting from the use ofRegistry Editor can be solved. Use this tool at your own risk.
Run Registry Editor (Regedt32.exe or Regedit.exe).
From the HKEY_LOCAL_MACHINE subtree, go to the following key:
Click Add Value on the Edit menu, and add the following:
Value Name: UserTokenTTL Data Type: REG_DWORD Data: (Number of Seconds for token to be cached - 30 sec. Min)
Note For IIS version 4.0, the minimum value is 30 seconds. For IIS 5.0, the minimum value is 1 second. If you set the value to 0, the minimum value will be used instead.
For IIS 6.0, the minimum value is 0. If this value is set to 0, TTL-based flushing of tokens is disabled. When TTL-based flushing is disabled, user tokens remain cached until either IIS is restarted or the worker process is recycled.
