Central Admin Pages showing a 404 Error

Question

I have an issue where I am getting a 404 error for some of the central admin pages but others work fine. Here are the pages that give a 404 that I have identified so far:

http://admin.portal.acme.local/security.aspx
http://admin.portal.acme.local/configurationwizards.aspx
http://admin.portal.acme.local/upgradeandmigration.aspx
http://admin.portal.acme.local/backups.aspx
http://admin.portal.acme.local/searchadministration.aspx
http://admin.portal.acme.local/searchfarmdashboard.aspx

Any ideas how I might go about resolving this? I am really close to just re-installing SharePoint to ensure a clean slate but that feels like overkill.

Answer 1

I have seen it where some of the application pages will become ungosted for lack of a better term when custom masterpages are applied to the central admin site and then removed. try opening the admin site up in sharepoint designer and checking out and then checking in each page that does not work.
