Assume you're connecting to the MS box with the Exchange IMC.  Might try
putting the host name/address in the LMHOST file on the Exchange box so it
doesn't have to query for the name.  Don't know if that'll help or not but
might be worth a try.  Normally requires a reboot, but there's a command to
make Windows reread the file.  Forget what it is at the moment, sorry...
