"The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server <servername$>" where servername is the name of the server specified as the MessageStats Connection Server

There is a Kerberos issue between the MessageStats server and the server specified as the Connection Server

Change the Connection Server to a different server until the Kerberos issue is resolved. To change the Connection Server:

1. Open the MessageStats console
2. Expand Organizations
3. Right click your Organization name and select Properties
4. Select the Connection Server tab
5. Enter the NETBIOS name of a different server to use as the Connection Server:

• If you are gathering against an Exchange 2007 or earlier Organization where there are no Exchange 2010 Mailbox servers, enter the NETBIOS name of a Mailbox server
• If you are gathering against an Exchange 2010 or later Organization where there is at least one Exchange 2010 Mailbox server, enter the NETBIOS name of a 2010 CAS server

6. Click OK

To resolve the Kerberos issue, please consult Microsoft documentation or contact Microsoft for further assistance.
