There are a number of small bugs with Microsoft Dynamics CRM 4.0 Update Rollup 2. Since they are quite hard to spot I’ve decided to spell some out here. If you know of anymore, please let me know.
- Corruption of web.config.
Solution: Delete web.config and rebuild app
- Corruption of certificates.
Solution: Re copy certificate
- System jobs not working.
Solution: See point 1 and 2. Fix is not very obvious. You can use advance find under system jobs and select the message column to find the exact error.
