Ok, I have done as much as I can without assistance When I try to start-edgesyncronization on the hub transport server it says "FailureDetails : The LDAP server is unavailable." I have tried removing the certificate from the Service account on Exchange ADAM, resubbed the server, same result. Then I tried "certutil -urlcache ocsp delete" and "certutil -urlcache crl delete" rebooted the TMG server then tried this on the exchange server, rebooted as well. no dice Re-enabled the exchange certificate and made sure the status wasn't revocationcheckfailure as it was before and still no dice. Although I just ran Exchange Best Practices and got "19:10:08.248: There is an error (The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)) on the WMI search SELECT __RELPATH, Name, Domain, TotalPhysicalMemory FROM Win32_ComputerSystem on scope root\cimv2 on server WIN-TMG-SVR.mydomain.com. Skipping object." However, I can do gpupdate /force on the TMG server so the firewall is not blocking RPC I can't Telnet into the LDAP edgesync port on the DC. So I am stuck here. More Info: The LDAP System policy rule is enabled and I still get denials on the log via the "Default Rule"

If you read my post, I have already tried that...

have you tried to disable "strict RPC compliance" on TMG lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

Yes, and now getting it on a FRESH INSTALL without TMG.. Getting a little upset...

Finally I have my answer... The server certificates were matching between the Edge and Hub. You CANNOT do that.. I hope to god that this becomes useful at some point for someone.
