Hello,
I have two Exchange servers running 5.5 SP4 in my Organization in two different facilities connected by a T1. Since I have out the second server in I get entries in the application logs like below. Mail is still getting through but I am concerned about the errors. I looked this up on Microsofts site and they reference a change in SP4 regarding the way RPC binds using DNS instaed of the ip address but it looks like both servers have no problem communicating with each other. Does anyone have any suggestions?

Any help is appreciated,
Thank you.
Mike
