CRM 2011 - The webpage cannot be found HTTP 404

Hi all!

I'm having an issue in a production environment with CRM 2011 UR6 + 2 organizations:
The default organization is accessible but the second one returns The webpage cannot be found HTTP 404 error.

I tried every single thing i could think of:

- IIS/Servers/SQL reset
- Dynamics CRM Repair
- Dynamics CRM Uninstall & Reinstall (!)
- Deleted & re-imported the organization
- Trace / EventLog / Fiddler - Return nothing
- Tried accessing with Hostname / IP / FQDN - nothing helped

Ideas anyone?

Thanks
