Well for the past week i have been battling with an IFD Server that is not on the main CRM server, so i logged a call with Microsoft and managed to get to resolve the issue, but i was still having problems accessing the AD Side of the IFD.....
I Checked all my IP Adresses by running IPCONFIG /all
This showed me that i had 6to4 Tunnel running, but i had unticked the IPv6 entries from the Adapters, so why was this still here?
so i then pinged the server from itself e.g ping serverurl
this was trying to ping an IPv6 Address, so i edited the registry as below:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters
Create a DWORD 32 bit Value and rename it to "DisabledComponents"
Double click it and type 255 in the value box, it will disable IPv6.
Restart!
Then when the server came back up i had no 6to4 tunenel and the ping was resolving to the IPv4 Address, then tried logging in from the server and hey presto!!!
The main reason for getting the machine to be able to login to CRM from itself via AD is that when running server based code e.g. Plugins, ISV customisations were failing with Error 4.01 as the server was trying to connect via the IPv6 Address which was disabled.
Hope this helps someone else !!
