I have been battling a problem with my exchange server 2003. The Exchange Server, that is also a backup DC, is unable to see the network but still functions as an Exchange Server. The email gets delivered, people are able to login from the road and retrieve their email, but when I try to view the network from the Exchange box I am unable to see any other computers, no computers can see it and am unable to add new user email addresses through AD. The event logs generate 2 errors all the time:
Event Source: MSExchangeSA
Event Category: RFR Interface
Event ID: 9074
Description: The Directory Service Referral interface failed to service a client request. RFRI is returning the error code:[0x3f0].
Event Source: MSExchangeSA
Event Category: RFR Interface
Event ID: 9143
Description: Referral Interface cannot contact any Global Catalog that supports the NSPI Service. Clients making RFR requests will fail to connect until a Global Catalog becomes available again. After a Domain Controller is promoted to a Global Catalog, it must be rebooted to support MAPI Clients.
I can ping other computers and printers on the network, I can ping it from other computers, I can use remote desktop to log into other computers and I can remote desktop to it from other computers. I can replicate to and from it with the other DC and can see it from the DNS manager. All security and permissions are correct.
Has anyone had this problem or heard of it? Any suggestions are appreciated
Thanks
