Subject: Weird routing between two Lotus Domino servers


Greetings!

We have two pair of Domino servers in NYC, and a pair of them in Illiois (all 
Win2003 standard server).  All are Domino 7.0.2 (for which service has been 
discontinued - EOL for that product version).

The way mail flows, all non-company mail addressed to those in Illinois is 
routed through one of the NYC Domino servers.  Consequently, if NYCDOMINO1 
cannot connect to ILNOTES1, then Illinois gets no outside mail.

For the past few years, we have had a WAN connection consisting of two bonded 
T1s (total 3 Mbps).  We now have a new fiber WAN connection (through a 
different vendor) at (currently) 45 Mbps.  All would be well, except for this 
screwy(!) routing issue...

ILNOTES1 (as well as other random IL machines) route to NYCDOMINIO1 through the 
new 45 Mbps pipe (using tracert in a command console).  NYCDOMINO1 routes to 
randomly selected IL machines through the new pipe, EXCEPT to ILNOTES1.

When we disconnect the old 3 Mbps router (at either the IL or the NYC end) and 
to a tracert ILNOTES1 (by any name or by IP address), it times out with the 
cheerful message "No route found to host".

The Windows network settings (including things like "NETBios over tcp" and 
"Allow lmhosts import") are identical but for host IP address.

I have checked all the files in [admin$]\system32\drivers\etc.  None of the 
files have any entries (other than the defaults one sees whenever installing 
Windows).

Any ideas where to look next?  We would really prefer not continuing to pay one 
vendor for a slow pipe for this single one-way connection.  (We would also not 
like having something this screwy in our network!)

Thanks for any suggestions...
