The Microsoft Exchange Server team have warned of yet another buggy update that Exchange Server 2010 customers need to watch out for. This time it is a .NET hotfix that impacts customers running Exchange 2010 on Windows Server 2008 SP2.
The symptoms of the problem are:
- Exchange Management Shell does not start
- Exchange Management Console does not start
- There might be a crash in Exchange Mailbox Replication Service (it is not clear yet if this is related)
- Event Viewer might have trouble opening
In discussing these recent dramas with other Exchange administrators it is clear that after a long run of trouble-free updates we've sadly returned to the days of thorough testing and a “wait and see” approach to installing updates on Exchange servers.
