Security Manager 6.x
Security Manager Web Console

IIS 6.0


Whenever you try to open the Security Manager web console, the ?Service Unavailable? error occurs and the web site does not appear.

The following two events occur on the central computer where the web console is installed.

Event ID 2268

Event ID 2274


There are 2 possible fixes, depending on your current configuration.


Fix 1:  

If ASP.NET 2.0, 64 bit version is the only .NET version installed, use the following process:

  1. Download and apply 2.0 SP2 (NetFX20SP2_x64.exe) on the Central computer. 
  2. Restart IIS
  3. Attempt to open the Security Manager web site

Fix 2:
Download and install 2.0, 32-bit version using the following steps:

 ASP.NET 2.0, 32-bit version

To run the 32-bit version of ASP.NET 2.0, follow these steps:

  1. Click Start, click Run, type cmd, and then click OK.
  2. Type the following command to enable the 32-bit mode:
    cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
  3. Type the following command to install the version of ASP.NET 2.0 (32-bit) and to install the script maps at the IIS root and under:
    %SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
  4. Make sure that the status of ASP.NET version 2.0.50727 (32-bit) is set to Allowed in the Web service extension list in Internet Information Services Manager.
  5. Verify your Security Manager Web Console now functions normally.



When you install both the 32 bit and 64 bit versions of ASP.NET, you may receive error messages if you do not perform steps to enable each ASP.NET environment to run in Microsoft Internet Information Services (IIS) 6.0.
