Hello, Our exchange server has stopped delivering emails after running the windows update on our SBS server. We are running Exchange server 2008, on our SBS 2007. I can see the server for exchange is running in local services, but when I use the "Microsoft Exchange Troubleshooting assistant" to look for failures, it responds: Found 1 failure events for all processes. This error provides no further information or specifies what the error is, or steps to resolve it I don't see any alerts or error messages, and I was only alerted to the issue because all incoming, and outgoing mails failed to be delivered. Should I be using a different tool to troubleshoot Exchange issues? **edit** I just ran a troubleshooting assistant for mail not being received by users, and it returned this error: Network Adapter IPv6 Address not supported Exchange server is not capable of supporting Internet Protocol Version 6 (IPv6) addresses on server SBS. An IPv6 address was found on adapter Broadcom NetXtreme Gigabit Ethernet. Any help is greatly appreciated. ~ Confused

I recommend you post your question to the SBS newsgroup since they're more versed on the interdependencies and interrelationships between the various components of SBS. http://social.technet.microsoft.com/Forums/en/smallbusinessserver/threadsEd Crowley MVP "There are seldom good technological solutions to behavioral problems."

Thanks, I will post in that forum.

Please check the article below which give more idea on IPV6 with Exchange Server component. IPv6 Support in Exchange 2007 SP1 and SP2 http://technet.microsoft.com/en-us/library/bb629624(EXCHG.80).aspx Actually, in Windows 2008, the IPV6 cannot be disabled completely even though the interface and connection is disabled. At this stage, I suggest you refer to the following article to troubleshoot the issue. http://social.technet.microsoft.com/Forums/en-US/exchangesvrtransport/thread/a9b1a718-7b22-4678-aa91-c8ecebb4c6fa Thanks.
