Finally I resolved my own issue, here it is for thosse of you who are having problems with this error
Clear the Config Cache
SharePoint maintains a disk cache based configuration on every server that contains the topology information and timer job definitions in “C:\Documents and Settings\All Users\Application Data\Microsoft\SharePoint\Config\<guid>\”.
Because old .xml files can get stuck here we may need to kick start the timer by clearing it.
The procedure is straight forward and needs to be carried out for every server:
- Stop the Administration and Timer service
- Delete all XML files in the directory (not the folder itself)
- Open “Cache.ini” and write the number 1 instead of the existing number (you might want to make a note of it)
- Start the services again
- Wait for a minute or two and see if the folder starts to fill up with xml files. It is likely that it will contain less than before clearing it.
- Check the cache.ini file. If it’s accessible and the number is considerably greater than 1 your cache has been properly initialized and chances are that your problems are now fixed. It didn’t fix my problem, so you may need to read on… (if you didn’t have the “888k” log entry mentioned above you probably have it now)
Note: Do not delete the Config Cache Folder!
