i have read this one. and the solution is not hard, just do it manually.
Below is the steps:
1) First, the easiest: Edit the web.config file, found on the CRM webserver, probably at C:\Program Files\Microsoft Dynamics CRM\CRMWeb. Within the file, find the line "authentication strategy=..." and change it to "authentication strategy="ServiceProviderLicenseAgreement".
(IFD had done this for you rite?)
2) On the CRM webserver, use the IIS Manager and open up the properties of the CRM website. Enable Anonymous Access to the website. Leave Integrated Authentication enabled as well.
3) Within the registry of the CRM server, run regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM. Add a new string value, named IfdInternalNetworkAddress. The value of this key should be a local IP address, then a dash, then the subnet mask.
Make sure there are NO SPACES before, after, or in the middle of the value. Example:
192.168.1.200-255.255.255.0 .
4) To add the necessary values to the SQL database, start up SQL Management Studio and connect to the SQL Server running your CRM databases.
a) In SQL Mgmt Studio, expand 'Databases'.
b) Find the MSCRM_CONFIG database and expand it.
c) Expand 'Tables'.
d) Find the table called 'dbo.DeploymentProperties'.
e) Right-click the DeploymentProperties table and select 'Open Table'. (NOTE: Changes made in the table are immediate. BE CAREFUL.)
f) Look in this table for three records with a ColumnName beginning with 'Ifd'. IF THEY ARE MISSING, you need to add them, using the SQL Query Editor:
g) Click on the 'New Query' button. When the query editor opens, verify the tab at the top-left of the editor is labelled with the name of the DeploymentProperties table.
h) In the query editor, enter
INSERT INTO DeploymentProperties (Id,ColumnName,NVarCharColumn) VALUES ('whatever value is in your other records','IfdRootDomainScheme','HTTP') /* change to HTTPS if you want */
INSERT INTO DeploymentProperties (Id,ColumnName,NVarCharColumn) VALUES ('whatever value is in your other records','IfdSdkRootDomain','your Ifd Root domain')
INSERT INTO DeploymentProperties (Id,ColumnName,NVarCharColumn) VALUES ('whatever value is in your other records','IfdWebApplicationRootDomain','your Ifd Web App Root Domain')
Press the 'Execute Query' button, and the three records should be added to the DeploymentProperties table.
Once all of the above is accomplished, your CRM system should be accessible from outside of your firewall.
