As I know, EMC (EMS) is connecting to server remotely even on the local exchange server Does the issue happen on the domain workstation? Is there any error event in the application log on the remote workstation and exchange servers? Please run the failed cmdlet with “Verbose” parameter, and check the output You can also increase the diagnostic logging on the services below: · MSExchange Configuration Cmdlet - Management Console · MSExchange Configuration Cmdlet - Management Shell · MSExchange Configuration Cmdlet - Remote Management Resources: OWA: The process failed to read the Exchange topology in the allotted timeJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Thank you for the reply. Yes, it is a domain joined workstation. I will re-try the commands with the -verbose switch, check the logs, and check / adjust the logging levels. I did see the other thread before I posted, and checked my site and subnet configurations looking for the guid-tagged subnets, but everything looks in order there, and my OWA seems to be working fine.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Okay. I've figure out how to get the cmdlets to work. I've been running them out of the Powershell Modules console that installs with RSAT. This console will automatically import all of the Exchange cmdlets into the console if you have the Exchange Management tools installed. They all seem to work, except for the 4 UM-related cmdlets. If I launch the ESM from the Exchange 2010 program group, they work from there. I edited the profile of the Powershell Modules console ( just open it up and run NotePad $profile) and pasted in the command line options from the ESM shortcut: . 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1' cd \ Connect-ExchangeServer -auto Now the UM specific cmdlets work.
