Hi Guys, Does anyone encoutered this in Event Viewer? "NSPI Proxy cannot contact any Global Catalog that supports the NSPI Service. New clients will be refused until a Global Catalog is available. After a Domain Controller is promoted to a Global Catalog, it must be rebooted to support MAPI Clients." _____ Access over 1 million songs - Yahoo! <http://pa.yahoo.com/*http:/us.rd.yahoo.com/evt=36035/*http:/music.yahoo.com /unlimited/> Music Unlimited.
