Hi Everyone,
I've been having issues with clients connecting to an existing Exchange server (Getting login prompt- but not usual reason).
We currently run Exchange 2010 with approx 200 mailboxes on the server. Last night I renewed the certificate on the 2010 server (go daddy SAN cert, all ok) and added the cert to my new Exchange 2013 server. I tested it with my account, and a test account approx 12 times, and had not login prompt when launching Outlook. All seemed ok, until this morning.....
This morning, most (not all) users are getting the login prompt. We are able to get by this by inputting domain\username and Outlook opens fine and is able to connect. No users are on the Exchange 2013 server yet (only 1 test account)
I've been googling all morning and I'm not seeing anything directly relating to my issue. I've read about the Anon vs Negotiate issues (KB2834139) - But - the strange thing is all clients are set to negotiate network security (And encrypt data) This is opposite of what the MS article says. CLients are all Outlook 2010
Here are my outlook anywhere settings:
ServerName : exchange2010IISAuthenticationMethods : {Basic}
ServerName : exchange2013A
IISAuthenticationMethods : {Basic, Ntlm}
ServerName : exchange2013B
IISAuthenticationMethods : {Basic, Ntlm}
Identity ClientAuthenticationMethod IISAuthenticationMethods
-------- -------------------------- ------------------------
exchange2010\Rpc (Default Web Site) Basic {Basic}
exchange2013a\Rpc (Default Web Site) Ntlm {Basic, Ntlm}
exchange2013b\Rpc (Default Web Site) Ntlm {Basic, Ntlm}
If I change the Exchange 2010 server to NTLM, will this resolve what I'm seeing? And do I need to restart RPC Client Access and Transport Service to make changes take effect? Or reboot the whole server?
If you need more info or logs please let me know
Thank you for any help!
