I am facing a weird issue..

I stood up a new server on a remote site and am trying to access it's ECP using the server FQDN but I get an error message within IE saying "Error executing child request for /owa/auth/errorFE.aspx

I figured I'd try with my existing servers, I am getting the same thing. The only way I can get into ECP is by using the External address..

Figured I would have a look at the ECP Virtual Directory through the shell but when I try to get the authentication information, it takes forever and doesn't return results... If I try through ECP (using the external address), I cannot open the auth page, I get the please wait box for hours..

Anyone ever experienced this?

Hi mdeschenes,

Thank you for your question.

If there is coexisted with Exchange 2010, we should access ECP by: https://<FQDN of CAS>/ecp/?ExchClientVer=15

First, make sure Exchange could connect to DC without any problems(include DNS resolve) and DC replication is no problems.

Then make sure the following authentication has been checked:

1.        Default website: Anonymous
2.        ECP: Anonymous and Basic
3.        OWA: Basic

Then restart IIS service by running iisreset /noforce from a command prompt window to check if the issue persist.

We could check if there are any errors in application log and post them for our troubleshooting.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
