Okay, we have recently migrated Exchange servers. The old: Exchange 5.5 SP3 on NT4 SP5. The new: Exchange 5.5 SP4 on Win2K Server. The new server is 800MHZ, 256MEG. It's performance is mildly sluggish but when we attempt to access public folders it take a minute or more and sometimes times out. The minute that I bring the other (old) server online, the Public Folders come up in a snap. Performance monitor says memory usage is fine as well as processor usage. However, I don't know what could be causing this bottleneck. Is this a configuration issue with public folders and Exchange or do I need to beef up the new server?
