http://www.msexchange.org -------------------------------------------------------I have some oddity going on, in that my 3 different exchange servers keep removing and add themselves to the Exchange Domain Servers group. This ended up causing an issue this morning where 2 of the 3 servers couldn't communicate via DSAccess and do anything to let mail flow. Adding the servers to the group and rebooting them fixed it. I ended up rebooting all 3 servers (at different times) and adding them all to the group. After 20 minutes, the servers started adding/removing themselves again. The only thing that I can attribute to a cause of this is that last Friday afternoon I raised my domain functional level from mixed-mode to Windows 2003 native. All of my DC's are 2003 SP1 and my 3 Exchange servers are 2003 SP2. Things were perfectly fine with the mail servers all day Friday, Saturday, Sunday, and until around 7am this morning, and then things went to hell. Has anyone seen this behavior and know why the servers still keep randomly adding/removing themselves from the Exchange Domain Servers group? ------------------------------------------------------- List Archives: //www.freelists.org/archives/exchangelist/ MSExchange Newsletter: http://www.msexchange.org/pages/newsletter.asp MSExchange Articles and Tutorials: http://www.msexchange.org/articles_tutorials/ MSExchange Blogs: http://blogs.msexchange.org/ ------------------------------------------------------- Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------- To unsubscribe visit http://www.msexchange.org/pages/exchangelist.asp Report abuse to listadmin@xxxxxxxxxxxxxx
