The Cluster service may not remove all file share entries
from the LANMANSERVER key during shutdown if there is a large number of shares.
This may cause problems when you next start the computer, depending on the size
of the SYSTEM hive. The SYSTEM hive is where the LANMANSERVER key is located.
The following log may be generated in the Event log for each value that is left
in the key:
Event Type: Warning
Event Category: None
Event ID: 2511
The server service was unable to recreate the share user12604
because the directory r:\users\user12604 no longer exists. Please run "net
share user12604 /delete" to delete the share, or recreate the directory
If the node is running Windows 2000, the
computer may fail to start, and you receive the following error message the
next time you restart it:
Windows 2000 could not start
because the following file is missing or corrupt:

first screen to start repair.
This behavior occurs because the Cluster service may not
have enough time to remove all of the values from the LANMANSERVER
Services typically have 20,000 milliseconds (20 seconds) to shut
down. If a service requires more time to shut down, it can be written to work
with Service Control Manager (SCM) to extend the amount of time it requires to
shut down. The Cluster Service does not adhere to this registry value.

How to Increase Shutdown Time For Services To Close Properly
The Cluster service normally does not require more
than 20 seconds to shut down. Programs that are running on a cluster, such as
Microsoft Exchange and Microsoft SQL Server, may require more than 20 seconds
and work SCM to allow for longer times to shut down. Because the Cluster
service shuts down in 20 seconds, it may not have enough time to remove all the
values from the LANMANSERVER key.

problems that may require you to reinstall your operating system. Microsoft
cannot guarantee that you can solve problems that result from using Registry
Editor incorrectly. Use Registry Editor at your own risk.
For Windows 2000, if the SYSTEM hive grows beyond 10 to 12
megabytes (MB), the node may not be able to start. If you have a large enough
amount of files shares on the cluster that it could cause the SYSTEM hive to
grow to an unacceptably large size, use the following procedure to recover the
node so that it will start. After you can start the node, migrate some of the
file shares to another server to reduce the possible size of the SYSTEM hive,
and to prevent this behavior from reoccurring.
