Access Denied error is thrown sometimes when connecting to an Exchange Server 2003 SP1 server. The cmd-let used to connect is:
Set-ExecutionPolicy RemoteSigned $sessOpt = New-SessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck $credent = Get-Credential $session = New-PSSession -SessionOption $sessOpt -Credential $cred -Authentication Kerberos -ConfigurationName Microsoft.Exchange -ConnectionURI http://ex1/Powershell
System.Management.Automation.Remoting.PSRemotingTransportException: Connecting to remote server ex1.domain.com failed with the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic
The above error is thrown for few attempts and after sometimes it works. The same cycle repeats. Unable to find why the Access is denied for few attempts. Tested in different machines with same result.
