New IE7 security feature.

In the new IE7, it will include a new feature called ‘Delete Browsing History’ which will let the users to control the data stored by the browser easily. By using this feature, we can tighten the security of IE easily.


For example,  we can use a single setting page to control all of the internet data saved in IE.

Such as the history, cookies, web caches, internet password can be cleaned easily.


We don’t need to browse to difference setting page to clean those data.


Here is a sample of the setting page:

Delete Browsing History dialog


After all, in the old day when we clear the Temporary Internet files, IE will be freeze until the cache was clear….but now, we can switch back for browsing web site and keep the cleaning process running in the background. Really nice feature!

How to fix corrupted IPSec policy on W2K3 DC

On Windows Server 2003 DC, if the IPSEC policy was corrupted, the server machine couldn’t determine what traffic was allowed and what traffic wasn’t, so it took the safe route and discarded all traffic that wasn’t permitted by the highly restrictive boot-time policy exemptions.

In order to fix it, we need to fix some registry keys from the command line:

  REG DELETE HKLM\SOFTWARE\Policies\Microsoft\Windows\IPSec\
   Policy\Local /F

  REG ADD HKLM\System\CurrentControlSet\Services\IPSEC /V
   Start /T REG_DWORD /F /D 1

  regsvr32 -s polstore.dll

When the policy file corrupted and couldn’t be read, IPSec will be defaulted to “Block” mode, it will blocks most traffic except DHCP, which the computer would need to start up. By deleting the local policy, reconfiguring the IPSec service and re-registering the policy store (it will recreates the default local policy), we can solve the problem.
