MAPI Sessions Exceed Maximum Over Permanent VPN Tunnel
Posted on 2007-08-07
Svr OS: Windows 2003 SP 2
App: MS Exchange 2003 SP 2
Client: Windows XP w/ MS Outlook 2003
I receive "Mapi session "/o=<compname>/ou=First Administrative Group/cn=Recipients/cn=<user.name>" exceeded the maximum of 100 objects of type "session"
Originally, I believe it said 32, but I read up on an article that said, tho inadvisable, you could increase the session #. Unfortunately, like all bandaid approaches, this one fell off lol.
I know that most of the time, these error messages, that incidently result in the user only being able to log in through webmail, are caused by an application continually pinging the server. The odd thing is this:
This only happens in our remote Network Operations Center. The systems, the way they log in, the domain, all things are the same with the ppl in the remote NOC as they are with the ppl in this office, but the error messages have only ever occurred with names in the NOC. When we first implemented the NOC, a downgrade of the Cisco software needed to occur b/c it was breaking up packets and wouldn't let someone be added to the domain. Could there be something else with the configuration of the tunnel that is causing this continual 'pinging' that maxes the sessions for these users?
