Error at the last step of first Ex2010 HT installation
Hi everyone, I am in the middle of installing Exchange 2010 servers. And CAS servers have already been installed without any issues. But when installing the first HT server, the setup completed with the results of "The followingserver roles have not been installed. "Elpased Time: 00:27:52 "Setup was unable to successfully install" And in Hub Transport Role part of the step-by-step pane, Hub Transport Role Failed "Error "The following error was generated when "$error.Clear(); $vdirName = "PowerShell"; $InternalPowerShellUrl="http://" + $RoleFqdnOrName + "/powershell"; new-PowerShellVirtualDirectory $vdirName -InternalUrl $InternalPowerShellUrl -DomainController $RoleDomainController -BasicAuthentication:$false -WindowsAuthentication:$false -RequireSSL:$false; " was run: "An error occurred while creating the IIS virtual directory 'IIS://ThisHTServer.company.com/W3SVC/1/ROOT/PowerShell' on 'ThisHTServer' "Could not load file or assembly 'Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

Could you please let me know what happened to my installation and how I can fix these problems? Thanks in advance, Eric

Make sure that all the prerequisite roles and features are installed: http://technet.microsoft.com/en-us/library/bb691354.aspx Then try running Exchange setup again.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Thank you both Maher and Ed. I also found this link "Exchange 2010 install fails on step 9" http://social.technet.microsoft.com/Forums/en-US/exchangesvrdeploy/thread/03dc1720-a934-41b0-b839-06894eb769e9/ and got an idea from Aaron Penman's answer. I checked my CAS, which was successfully installed, again my HT server and found the feature of "Remote Server Admin Tools -> Role Admin Tools -> Web Server (IIS) Tools" was not installed. And I had an error saying "An error occurred while creating the IIS virtual directory 'IIS://ThisHTServer.company.com/W3SVC/1/ROOT/PowerShell' on 'ThisHTServer'. Could not load file or assembly 'Microsoft.Web.Administration, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified." And I realized 'Microsoft.Web.Administration, Version=7.0.0.0' is "Remote Server Admin Tools -> Role Admin Tools -> Web Server (IIS) Tools" So you do not need me to tell you that the installation is finished successfully after this mentioned feature was added. I think the Installation Wizard misses this as a prerequisite. Thanks again to everyone. Eric
