SYMPTOMS
The Exchange 2000 services may not start on a Windows 2000 Server-based computer that is a member server in an Active Directory domain, you may receive the following error messages, and you may not be able to manually start the Exchange 2000 services after the computer starts:

MSExchangeSA,

Error,

General,

1005,

N/A,

Server,

Unexpected error the specified domain either does not exist or could not be contacted.

MSExchangeDSAccess,

Error,

None,

2064,

N/A,

Server,

Process INETINFO.EXE (PID=1336). All the remote DS Servers in use are not responding.



CAUSE
This behavior can occur if you define local Internet protocol security (IPSec) policies that allow only secure communication between the Exchange 2000 server and the Global Catalog server.



RESOLUTION
To resolve this behavior, you can modify the IPSec policies on the Exchange 2000 server and on the Global Catalog server if you can lower network security in your environment. To do this, set the Security methods for the Filter properties to Accept unsecured Communication, but always respond using IPSec and Allow unsecured communication with non IPSec-aware computers so that there is a &quot;fallback&quot; to unsecured communication when IPSec is not available.



MORE INFORMATION
In a Netmon trace you can view unsecured communication attempts that occur when the computer starts. You can view unencrypted Domain Name System (DNS) frames that are never answered because the DNS server is set to allow only IPSec communication. If you are running the DNS server on the same computer as the Exchange 2000 server, you can work around this behavior. However, if you work around this behavior, the Exchange 2000 server sends unencrypted Lightweight Directory Access Protocol (LDAP) frames to the Global Catalog server that will never be answered because the Global Catalog server is set to allow only IPSec communication. When this occurs, the Exchange 2000 services do not work. The behavior is not resolved when you set Service Recovery to Restart Service and Interval 3 minutes.
