Killed old server (NT4 Ex5.5) about 4 months back. Client has been complaining about slow Outlook access ever since. Just noticed that when Network is loaded, a dialogue box pops up in OL which basically says that I can cancel a request of info from server MAIN (old server). Have checked e-mail accounts, & registry for any references to MAIN and cleared out. Customer says issue still occurring. New server is called SERVER2 and is Exch2000. What am I missing?
