EventID: 1194 Source: MSExchangeIS Description: Accept client on external interface NNTP failed with error 0x80004005 CAUSE ===== Windows NT 4.0 Service Pack 4 causes NDISWAN Services to return IP addresses in the order in which they are bound. This change results in IP addresses not currently bound to the TCP/IP stack being returned when making a call to the Winsock API function GetHostbyName(). Microsoft Exchange Server fails to register Internet protocols with these IP addresses. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to: - http://www.microsoft.com/Windows/ServicePacks/ -or- - Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For information on obtaining the individual software update, contact Microsoft Product Support Services.

This problem was first corrected in Windows NT version 4.0 Service Pack 5. MORE INFORMATION ================ NNTP is another protocol that Exchange supports and this error can occur with this protocol for the same reasons.
