Exchange 2010 not accepting external messages
All, I am having a problem between two of my exchange 2010 R2 servers. They are at different sites. When server 1 tries to send external email to server 2, the following error is in the queue:
451 4.4.0 Primary target IP address responded with:" 421 4.7.0 too many errors on this connection, closing transmision channel." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failover.
My first research pointed me something with the queue database, but we have 25 gigs free on the Server 2.
This just started last night, and I have yet to find a resolution. Any help would be appreciated.

This looks like you are having a disk space problem at Server 2. The free space should be higher then 4 GB atleast.
ASKER
Free Space is 25G, if I move the queue as described in the link I posted, would my user's lose on the email that is currently queued on Server 1 waiting to get to Server 2?
No I mean the space is short on server 2 and if you change the queue on Server 2 and it doesn't have the emails arrived in the queue then you can change the Queue.
You dont need to change the queue on server 1 as you said it has 25 GB of space left.
Also paste the link i cannot see the link.

Hi
How are you connecting the two sites? If you have 25GB worth of space then you don't have a space issue.
I would investigate your route between sites (post the network hardware you are using may be useful).
Alternatively it may be an issue with your receive connector setup - has communication ever worked between these two sites?
Does e-mailing externally work?

Sorry, the link I was looking at is:
http://technet.microsoft.com/en-us/library/f170cb0c-04a9-4fa7-b594-206e3a787e14.aspx
And yes, these two sites have worked for almost a year just fine.
I tried to move the queue, but now the Exchange Transport Service is hanging.

If you are running Exchange 2010 RTM (not with SP1), you need atleast 4GB free space on the drive you have the Hub transport queue.
Do you have that? If not, make space or move the queue to a different drive which has space.
Which version of Exchange is it, sp level?

I'm not sure if I am missing something here but the question does state
"25 gigs free on the Server 2."
So moving the message queue is not a requirement.
There is obviously a resource issue but if there is this much disk space then it could be CPU or memory

For whatever the reason, moving the queue worked regardless. Thank you for all your help.
