Note: This setting will be replicated to all Active Directory servers within the forest. You do not

have to restart domain controllers or Global Catalog servers for this to take effect.

Under normal circumstances, Exchange 2000 will access Global Catalog servers and the

user partition of domain controllers by consulting a dynamically created list of available

servers. While this is fine in the majority of circumstances, in some environments you might

want to change the behavior to maintain performance. For example, you might have some

underspecified domain controllers on your network, and you might wish to prevent these

from being used. Or you might have very slow links in your environment and you might

want to prevent servers running Exchange elsewhere in the domain from using these

Global Catalog servers or domain controllers.

To ensure that particular domain controllers or Global Catalog servers are used to service

requests, you can statically configure DSAccess to channel directory service loads to a

specified set of directory-service servers.

You should think carefully before deciding to statically define these entries, as you generally

run a greater risk of losing directory access entirely. DSAccess does not check to see if the

names you specify are valid, so if you spell server names wrong in the registry, you can end

up with a loss of service. Also, if static entries have been defined, then Exchange will not

check dynamic entries, even if the static ones are invalid.

The following entries can be added to statically define domain controllers and Global

Catalog servers:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeDSAccess

\Profiles\Default\UserDC1 (UserDC2, and so on)

IsGC = REG_DWORD 0x0

HostName = REG_SZ DC_DomainName.CompanyName.com

PortNumber = REG_DWORD (0x185 by default or 0x27C for SSL)

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeDSAccess

\Profiles\Default\UserGC1 (UserGC2 and so on)
