Error Code Gotchas due to Policy Settings

I run into a few problems on almost every SharePoint install.
David Szabo has put together a great post on some of the common ones:

I've also run into issues with search not being able to search itself. This is due to a registry setting to prevent the server from DOS'ing itself. Make sure you add all the possibly URL's that your site is running to the registry setting.

One more thing that always seems to come up a few months after the SharePoint portal has been up and running causes IIS to lock up. You'll get lots of errors in the event log for 6398, 7076, and 6482. You also won't be able to administer IIS. This has to do with two processes trying to access IIS admin service at the same time.

Install IIS Hotfix KB946517 and restart. This should fix the issue.


Problems with the timer service can also be caused by the scheduled task service being disabled. You'll re-enable it and it will turn off again. This is due to a group policy setting shutting it down. Have whoever manages the policy settings disable that setting on your sharepoint machines.

Errors with DCOM settings:
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID - Error 10016

I'm sure there will be more to come as I remember them.
