Hi, I am running all of my servers on Win2KSP2.
I have set up a second Domain Controller (on a different subnet) to provide redundancy for my Primary DC, but especially to keep Ex2KSP1 operable. I have also marked this DC to be a Catalog Server. However, when I disconnect my original DC from the network, & then attempt to open Outlook on a client, access to the Outlook mailbox is unavailable. Exchange logs the following error; "Event Type: Error Event Source: MSExchangeSA Event Category: NSPI Proxy Event ID: 9057 Date: 22/11/2001 Time: 8:52:48 AM User: N/A Computer: SNAP Description: 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. " I have rebooted the DC several times. Can someone advise me what I am doing wrongly & how I can enable the 'backup' DC to fufill Ex2K's requirements so that clients can use Outlook?
