I hope some one can help me out on this as it's driving me crazy. I've had W2K3 running perfectly with AD in our Frankfurt office for the last 6 months. Management decided that they wanted our London office to access this. Created a site-to-site VPN tunnel from Frankfurt to London (working fine) Created a new AD controller in the London office connecting to the AD in Frankfurt, all within the same domain name (working fine) Created a new W2K3 server in the London office which connected perfectly. I can view both servers in system manager I can create a new account/mailboxes on the AD controller in London and it's replicated to the AD in Frankfurt ....and vice-versa Now the problem: I can't send emails from a mailbox hosted on the London server through the server in Frankfurt (vice-versa), I can see the email just sitting in the mail queues ...but if I move the mailbox to the Frankfurt server all is well. the only warning message I'm getting is this: "Message delivery to the host '192.168.xxx.xxx' failed while delivering to the remote domain 'charon.name.com' for the following reason: The semaphore timeout period has expired." but i can't find any info about this. Before doing this in London I setup a secondary exchange in Frankfurt which connected fine with mailboxes passing email through to the main server with no additional configuration. Am I missing something? thanks --Mark
update.... after reinstalling W2K3 and W2K3E in the London office, I managed to get emails outbound via Frankfurt from a mailbox in London to an external account....but not internal. ...and no inbound to the London office from external mails. everything was getting stuck in the queues. dunno how I came to the conclusion that it was the "fixup protocol smtp" within the pix firewalls but hey call it divine inspiration after working on this for the last 2 days. ....but that was the problem thanks for reading --Mark "Mark" wrote: > I hope some one can help me out on this as it's driving me crazy. > > I've had W2K3 running perfectly with AD in our Frankfurt office for the last > 6 months. > Management decided that they wanted our London office to access this. > > Created a site-to-site VPN tunnel from Frankfurt to London (working fine) > Created a new AD controller in the London office connecting to the AD in > Frankfurt, all within the same domain name (working fine) > Created a new W2K3 server in the London office which connected perfectly. > > I can view both servers in system manager > I can create a new account/mailboxes on the AD controller in London and it's > replicated to the AD in Frankfurt > ...and vice-versa > > Now the problem: I can't send emails from a mailbox hosted on the London > server through the server in Frankfurt (vice-versa), I can see the email just > sitting in the mail queues > ..but if I move the mailbox to the Frankfurt server all is well. > > the only warning message I'm getting is this: > "Message delivery to the host '192.168.xxx.xxx' failed while delivering to > the remote domain 'charon.name.com' for the following reason: The semaphore > timeout period has expired." > but i can't find any info about this. > > Before doing this in London I setup a secondary exchange in Frankfurt which > connected fine with mailboxes passing email through to the main server with > no additional configuration. > > Am I missing something? > > thanks > --Mark
