Exchange 2007 event id 2161 and 2157

[dylan]

I have 2 Exchange 2007 servers in different locations and am using
Double-Take to replicate the data between them. One of them is the
production server, the other is strictly for Disaster Recovery. On
the Production server I'm getting these messages every 15 minutes:

It's obviously something looking for the public folders on the DR
mailserver, but I don't know how to make it stop looking for them.
Does anyone have any idea why it would be doing this and how to make
it stop?

It is probably due to your DR server being offline. Does DoubleTake
recommend changing anything in regards to Public Folder replication?
Maybe DoubleTake's support team can help you identify the problem? It
seems like ADAccess by default is set to the lowest logging level, but
you may want to verify that it is still set to that level. See
