Unable to access the Symantec Management Platform (SMP) Console.
HTTP Error 503 while opening the SMP console.
Noticed below error while opening IIS manager:
Cause
applicationHost.config ( C:\Windows\System32\inetsrv\config\ ) is corrupted and shows file size 0 KB.
Resolution
Navigate to "C:\inetpub\history" directory. You will find the history of all the applicationHost.config files in this directory.
Use one of the latest applicationHost.config file from this directory that you know is not corrupted.
You need to copy this applicationHost.config file and paste it into the "C:\Windows\system32\inetsrv\config" directory to replace the corrupted file.
Restart the IIS service.
Note: Sometimes, IIS service doesn't start if the applicationHost.config files gets corrupted and it gives the above error while accessing smp websites and application pool.
