CRM4 Installation error parsing config file

Installed Microsoft Dynamic CRM4 (64bit) on Windows Server 2008, IIS7, SQL 2005, SSRS2008, ISA2006 environment with IFD enabled using a config file last week and experienced a few errors:

1. Error parsing config file - The config file was very simple. I pretty much just copied and pasted the parameters from the implementation guide. Found out to be the actual copy and paste caused the problem. When copy and past from Microsoft Word document to notepad, it did not translate the " properly. Replaced all the funny " from the config.xml file, re-ran the installation, this error did not pop up again.

2. Error Active Directory groups and an organisational unit cannot be specified in the configuration file - found out to be I don't need to use the Active Directory group parameter if the security groups are pre-created. Removed the parameter referencing to the Active Directory groups resolved this problem.

3. Followed every word on KB950100 and avoided 7 potential errors listed on the article.

4. After the installation, had a blank crm web.config file. Backed up the web.config, copied from another web.config from the CRM4 Demo VPC and it worked.

5. IIS error 401.5 when browsing CRM using a host header. Still troubleshooting this issue. Confirmed it is not related to NTAuthenticationProviders, setspns. Performed a Network Monitor trace, found to be Response Too Big for UDP. Will let you know later when this is resolved.
