ipsec service fails to start and no network

apparently a known issue.  had no network after some windows updates on a windows 2003 VM

in the eventvwr:

The IPSec driver has entered Block mode. IPSec will discard all inbound and outbound TCP/IP network traffic that is not permitted by boot-time IPSec Policy exemptions.

The IPSEC Services service terminated with the following error:
The system cannot find the file specified.

  • check if there are any entries in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local
  • if so, delete that subkey
  • then run regsvr32 polstore.dll
  • restart the ipsec service

Old habits die hard.  Used to be able to launch dsa.msc from any (terminal) server you’re currently logged on to ?

You’ll need to install the W2K8 feature AD Snap ins and command line tools.

with powershell :

PS C:\Windows\system32> Import-Module ServerManager
PS C:\Windows\system32> Add-WindowsFeature RSAT-ADDS-Tools

Required IIS role services in Windows 2008 for APP-V

make sure you install the following role services before installing APP-V 4.5 on Windows 2008

  • IIS6 Management compatibility
  • IIS management scripts and tools
  • IIS 7 Windows authentication

For the first 2 you might end up with an error installing app-V and rolling back : “The Installation program was unable to create the required IIS virtual directory”  (error 25120) If you don’t add Windows authentication, it’s possible that you can’t login to App-V (Error 0000C801)
