Now that we are starting to see our first hotfixes being released for Dynamics CRM 4.0, I wanted to let you know where you can review these as they are released.
Microsoft have published a Knowledge Base article here which will be updated with any new updates or hotfixes, as they become available.
Currently there are some updates to the Setup files for CRM 4.0 and also updated Help Files.
For me, the key issue that has been addressed is the "Microsoft.Crm.CrmArgumentException: Invalid domain name. Domain name is either invalid or unreachable" error that many of you reported running into during installations or upgrades.
