Just follow the link and the answer from Chinthaka. But what would have cause this in the first place? Having a look through the event logs I cannot find the source of why it did. Nothing changed and the first event log: Date: 2009/06/06 Event ID: 16023 Source: MSExchangeTransport User: N/A Type: Error Category: Configuration Microsoft Exchange couldn't start transport agents.

That might be difficut to say but I would also check log of file level antivirus scanning software to see if it is created any problem...Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
