CRM Registry Settings
Today we have a relatively serious topic: Registry Settings. Unfortunately this can be an extremely boring topic – so I have opted for a more casual and sarcastic style.
Microsoft Dynamics CRM 3.0 has a boatload of additional settings which many of you might be unaware of. These additional settings are stored in the registry of web server machines. If you don’t know how to edit the registry – then you probably shouldn’t be (as patrician as that sounds – trust me – it’s for your own good). Wikipedia has a nice overview of the Windows Registry or there is the rather dry MSDN version.
Let’s start with supported vs unsupported. If you modify a registry setting which is not documented in our SDK then it is an unsupported modification. The undocumented ones are used for the internal operation of the system: changing them only makes you look smart – it doesn’t actually make you smart. Those technical readers out there will be aware of the type of person I’m referring to: the one who unnecessarily modifies their registry to impress others.
Here is the list of items from the SDK which you can modify:

One of the most common settings to be modified is the maxfileuploadsize setting. It’s been blogged a couple times by some others but recently I’ve been getting a few questions about this. CRM restricts the size of files for import (for email attachments, regular attachments, sales literature documents and customization import files) via this registry key. The CRM client also has the same setting which it uses for uploading files. You can find the client key here: HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient.
If you are using the CRM integration products you can also adjust the database which the product uses.
Remember that any time you modify the registry of your CRM implementation you will need to make these changes on all the web services in the load balanced cluster.
