Outlook 2003/Exchange 2000 Connection Problem

I maintain six offices which connect to the Exchange server via VPN over DSL. This has been working for several years, and I am completely baffled as to why it has stopped working.

In two of the six offices I maintain, I am seeing the following message in the event log on Windows XP computers which try to connect to the Exchange server.


Event ID: 19

RPC Call (EcDoRPC) to (mo-hq-s1.mo.loc) server failed with error code (6be) after waiting (82709) ms; eeInfo (none).

The VPN consists of FreeBSD servers in each office which connect to a central server in the main office. All offices are configured the same.

Any suggestions would be greatly appreciated.

Thanks,


Jay
 
RPC call errors would suggest that the VPN tunnel has a problem.

Can you test if the VPN is up? I'm not up on BSD at all.
 
Yes, I am able to ping the server(s) by name, and I am able to ping the workstations by name from the server. Response times are between 47ms and 55 ms for all the affected offices.

The offices which are not affected have response times between 47ms and 60ms.

Tracerts from the servers to the offices, and vice versa show the appropriate routes being followed.

Thanks,

Jay
 
Hey Jay, it's been a long time (think vpn,ipchains) ;-)

Did you get this resolved? Are these new XP computer that your just rolling out? Or were they in service before this problem came up? What name are you testing the pings with, just a machine name or a dns fqdn? Just tring to narrow the possiblities abit.
 
Yes it has!!!! If you want to e-mail me directly, we can catch up on what is going on.

I think we finally found the problems.

1. The Exchange server had lost its route to the local network. So ALL traffic, even traffic destined for the local network, was being routed through the default gateway. Big problem when replicating with the parent organization's servers. Fixing this made a dramatic difference in performance.

2. I have started using MPD for PPTP. The newer versions of FreeBSD now support PPTP windowing. Disabling this also produced a dramatic performance increase.

Thanks for your help.
