I had SolidCP 1.2.1 working on my local machine for a while. Then suddenly yesterday I started getting a “HTTP Error 503. The service is unavailable.” error. I tried to no avail a whole number of ways to fix it. Finally, I decided to uninstall and delete everything and reinstall with the latest version (v1.4.1) on my Windows 7 Machine. Installation was successful after a few failed attempts. I go to access the site, same error. I am at a complete loss…
The Event Viewer has three items:

  1. WARNING (5021): The identity of application pool SolidCP Server Pool is invalid. The user name or password that is specified for the identity may be incorrect, or the user may not have batch logon rights. If the identity is not corrected, the application pool will be disabled when the application pool receives its first request. If batch logon rights are causing the problem, the identity in the IIS configuration store must be changed after rights have been granted before Windows Process Activation Service (WAS) can retry the logon. If the identity remains invalid after the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.
  2. WARNING (5057): Application pool SolidCP Server Pool has been disabled. Windows Process Activation Service (WAS) did not create a worker process to serve the application pool because the application pool identity is invalid.
  3. ERROR (5059): Application pool SolidCP Server Pool has been disabled. Windows Process Activation Service (WAS) encountered a failure when it started a worker process to serve the application pool.

I checked the SolidCP accounts (Portal, Server, and Enterprise) and they appear to be defined correctly. I also check Local Policies and made sure that IIS_IUSRS was listed in “Log on as batch job”. I don’t know what else to try, and I have no clue why it worked last week and yesterday just decided to stop working.
Does anyone have any clues?
