Exchange 2007 temporary authentication error
Posted on 2011-04-28
We have 2 sites
Site A is HQ has single exchange 2007
Site B is sub-office with single exchange 2007
Site A & B connected by VPN.
Email flows from Site B to Site A over VPN then out to the world.
Email comes into site A travel over VPN to Site B
Was working fine then all of a sudden Mail stopped flowing to site B
Restarted exchange server went away
A week later it came back.
Queue filling up.
Site A could send email outside, but not to site B.
Queues reveal a "4.7.0 Temporary Authentication Failure"
Restart site A server and problem vanished. Email flowed
To me it looks like Site B server is not not authenticating Site A, but not sure why it would do that.
Pretty much all I can find is when folk have big installs of exchange with roles spread onto different servers.
I did see soemthing about certification errors online, but would have thought that would just be a problem all the time.
A restart of Site A server seems to cure it so I can't see that being an issue.
Also not very sure on these receive connectors - exchange 2000 previously and this is very different,
so not quite sure how they work. Site A has 3 of them Client, Internalrelay & Site A Mail in, Site B has Client and Site B in
Both sites have Default disabled.
