Sounds to me like the Catalog server is the one having the issue responding to the DNS call....at least according to the KB article.

Or is it my stupid head cold? I, for the life of me, by reading this KDB article, can not determine whether my server machine or client machine needs to be upgraded. http://support.microsoft.com/default.aspx?scid=kb;en-us;305596 The situation: Workstation: Windows 2000 SP1 running Outlook 2000 SR1 outside the network. Server: Windows 2000 Server SP2, Exchange 2000 SP2 I try to hook up to the server from outside the network (all traffic from specific IP is passed through the FW). I can connect but I get the following when Outlook runs: Unable to expand the folder. The set of folders could not be opened. The information store could not be opened. I checked the above article and am not sure which to upgrade (DON'T want to upgrade the server as of yet). If you feel up to it, I appreciate your comments.
