Internal Error 2878. Existing_WEB_Site

Problem Desciprtion:

I am attempting to install ArcGIS Server Enterprise 10 (.NET) on an Win7 x64 computer and I'm running into the above error.  It is annoying, but at least it is consistent.

"Internal Error 2878, Existing_Web_Site, ListBox, Default Web Site,80,1"

Solution 1:

For anyone who encounters this issue, I found an alternative fix.
The error seems to be a conflict regarding Port 80.
Therefore I went into IIS and renamed by Default Web Site to be Port 12345.
I then ran the DotNet  installation again, and it worked fine without the error blocking me out.
After installation I renamed the port back to 80 and restarted IIS.
All working fine now!

 

Solution 2:

You can start Windows PowerShell from the Start menu, from the taskbar, from the Search or Run box, from a Command Prompt window, or even from another Windows PowerShell session.

1) execute : poweshell
2) A command powershelle apear
3) paste this line to reset the default iis setpath: Set-Location 'c:\inetpub\wwwroot'
4) Go to the gisserver instalation and right click on the setup.msi and execute the msi file not the setup
