Salam, I have successfully installed Exchange 2010 SP1 on a transitional environment, the installation went smooth without any problem and I've done most of the trasitioning configuration from Exchange Server 2003 to Exchange Server 2010. Currently we're in the process of moving the mailboxes, but I've come across a problem recently which stopped all my work and I can no longer commence with this transition unless its solved. Sometimes when I try to access EMC or EMS I get the hereunder error: The following error occurred while attempting to connect to the specified Exchange server 'afhmail.arabfinancehouse.com.lb': The attempt to connect to http://afhmail.arabfinancehouse.com.lb/PowerShell using "Kerberos" authentication failed: Connecting to remote server failed with the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic. I've read most of the articles found on the internet including http://msexchangeteam.com/archive/2010/02/04/453946.aspx to try to troubleshoot this problem but nothing has worked so far, I tried removing Win RM IIS extensions as well then adding them again with a restart and nothing. I tried the Kerbauth dll removal also nothing and the problem keeps to occur and the situation is not stable. Also I read in a KB article somewhere that if we have multiple domain controllers a single domain controller should be assigned on the Exchange Server (Organization Configuration, Server Configuration, Recipient Configuration) so I assigned the PDC to be selected by those configurations at startup, yet I am still facing the same problem. Again I emphasis that the problem comes and goes, at a time I can access EMS and at another is just gives me the Kerberos error. Thank you very much in advance, Kindest Regards.Abdullah Abdullah

Hi, Hope this link might help you. http://blogs.technet.com/b/richardroddy/archive/2010/10/06/even-more-exchange-2010-management-tools-fun.aspx ThanksNagaraj N

ok you can take help of the troubleshooter discussed in this blog http://msexchangeteam.com/archive/2010/12/07/457139.aspx by the way looks like the error message you got does not match the cases discussed in the blog http://msexchangeteam.com/archive/2010/02/04/453946.aspx. Dhruv

Salam, Thank you Dhruvaraj, but I've used the troubleshooter as well with no luck. Currently I'm moving all mailboxes back to 2k3 and I'll do some more troubleshooting then. Thank you.Abdullah Abdullah

Hi Abdullah, Can you open the EMS? If yes, please run the WinRM QC and post the results here. If possible, please use another admin's account to log on to Exchange to try to open EMC.

I get the same error. Noone seems to have a solution...?!

Salam, Sorry for the late reply but I've been quite busy lately. Just wanted to inform you that the problem was resolved, it was mainly because error in the time setup of the exchange server. When I first installed Windows 2k8 R2 I forgot to setup the time zone and when the problem occurred I didn't notice, yet later on I noticed the time difference and adjusted the time zone, it worked for about 10 minutes and then the time zone was changed again. I tried many fixes yet every time I adjust the time zone it returns to its previous state, any way I moved back all the moved mailboxes to the Exchange 2k3 server and setup a new Windows 2k8 R2 server, kept a keen eye on the time and poof problem resolved and now everything is okay. Note: adjust the time zone before joining the server to the domain, also if the server is a virtual machine make sure you install the tools (e.g VMWare tools, etc..) and then adjust the time zone. Thank you all for your support and help, Kindest regards.Abdullah^2
