A. First, make sure you've installed the required prerequisites:
- ISAPI Extensions
- Basic Authentication
- Windows Authentication
- IIS 6 Management Compatibility
The common cause for this error if you meet the prerequisites is that your .NET installation is incomplete or corrupt. When you attempt to install the Clustered Mailbox Role, you'll get the following error.
'savdalex01'. Could not load file or assembly
Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of
its dependencies. The system cannot find the file specified.
The solution is to reinstall .NET 3.0, even though it may show as installed. This should resolve the problem.Related Reading:
