C:\php\php-cgi.exe - The FastCGI process exceeded configured activity timeout

That's a Server error, not a Browser error.  Check the PHP execution time limit in 'php.ini' and/or any execution limits in IIS.

how to change in fastcgi iis7
because php.ini says
max_execution_time = 400
memory_limit = 1028M

With that much time and memory, you need to find out what is going on in your PHP code.  Maybe your text file is too big and you need to break it into pieces.  In any case, you need to have a good PHP programmer fix it for you.

php code was working on another server

I am sure that it is a fastcgi problem

It might be.  I suggest you click on "Request Attention" and get some others to look at your question.  Maybe they will have some suggestions.

it is changed to 600
I dont know how to provide output because I can not find the file

Can't find what file? - Hades666

i cant give you the file
%windir%\system32\inetsrv\appcmd list config -section:system.webServer/fastCgi
because I can not find it

I am editing something that looks like the file using iis7
but I am clicking with a mouse and see textboxes and not a file

I don't want the file. I want to see the executed output from commandline.
Appcmd is an exe that is used to configure IIS from command line.
What that comannd does is print out the php settings onp your server which are stored in the application.config

C:\Windows\System32\inetsrv>appcmd list config -section:system.webServer/fastCgi

<system.webServer>
  <fastCgi>
    <application fullPath="C:\php\php-cgi.exe" arguments="" monitorChangesTo=""
stderrMode="ReturnStdErrIn500" maxInstances="4" idleTimeout="300" activityTimeou
t="600" requestTimeout="90" instanceMaxRequests="10000" protocol="NamedPipe" que
ueLength="1000" flushNamedPipe="false" rapidFailsPerMinute="10">
      <environmentVariables>
      </environmentVariables>
    </application>
  </fastCgi>
</system.webServer>

is this the correct output


C:\Windows\System32\inetsrv>appcmd list config -section:system.webServer/fastCgi

<system.webServer>
  <fastCgi>
    <application fullPath="C:\php\php-cgi.exe" arguments="" monitorChangesTo=""
stderrMode="ReturnStdErrIn500" maxInstances="4" idleTimeout="300" activityTimeou
t="600" requestTimeout="90" instanceMaxRequests="10000" protocol="NamedPipe" que
ueLength="1000" flushNamedPipe="false" rapidFailsPerMinute="10">
      <environmentVariables>
      </environmentVariables>
    </application>
  </fastCgi>
</system.webServer>
