DS Console slow?

From Microsoft KB article:http://support.microsoft.com/kb/296264/
By default, opportunistic locking is enabled for server message block
(SMB) clients that run one of the Windows operating systems that is
listed at the beginning of this article. Opportunistic locking allows
clients to lock files and locally cache information without the risk of
another user changing the file. This increases performance for many file
operations but may decrease performance in other operations because the
server that grants the opportunistic lock must manage the breaking of
that lock when another user requests access to the file.

On dedicated servers running Windows 2000 Professional, Server, Advanced
Server, or Windows XP Professional, create the following

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parame
ters

Create the following:
Value Name: EnableOplocks
Data Type: REG_DWORD
Parameter Value: 0 Hex (False)

(If your server is not a dedicated server you will also need to create
the workstation keys listed below.)

On workstations with Windows 2000 Professional, or Windows XP
Professional, in this key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanWorkstation\P
arameters

Create the following:
Value Name: UseLockReadUnlock
Data Type: REG_DWORD
Parameter Value: 0 Hex (Disabled)

Value Name: UseOpportunisticLocking
Data Type: REG_DWORD
Parameter Value: 0 Hex (Disabled)

Value Name: UtilizeNtCaching
Data Type: REG_DWORD
Parameter Value: 0 Hex (Disabled)

Reboot all servers and clients affected
