Server service auto-tuning and KB article

[DWalker]

KB article 314498 talks about the Server service and how it's self-tuning.
But if you set some parameters from the command line (like autodisconnect
for LAN connections), the server service is no longer self-tuning. To
correct this, you are told to follow a list of steps.

It's not possible to follow the steps as listed!

The article says this:

"To restore the LAN Manager Server parameters to their defaults, or to
reconfigure Windows so that it automatically configures the Server service,
follow these steps."

Step 6 says this:

"6. In the right pane of the Registry Editor window, delete all entries
except for the following:

EnableSharedNetDrives
Lmannounce
NullSessionPipes
NullSessionShares
Size

NOTE: You may have other entries here that are statically coded. Do not
remove these entries."

Does anyone else see anything odd about this? We are to remove all entries
except for the ones listed, BUT we're not supposed to remove some other
entries (that aren't listed) that are "statically coded". How are we
supposed to know what other entries that we might see are "statically
coded" and should not be removed? This step is impossible to follow as
written.

I submitted a comment on the article; maybe someone will take a look and
clarify it. But I won't hold my breath.

Is there a better way to restore the server service's auto-tuning if it was
inadvertently turned off by using the command "net config server
/autodisconnect:-1" for example?

Thanks.

Can you post the contents of the key?

Sure.

I predict the article was correct when written, but if you delete
everything except those entries mentioned, then right-click a local
disk, the context menu item "Sharing and Security" is missing (in
Windows XP Pro SP2), and all of your previously-shared disks are now
unshared.

Those are the same set of data place holders that I have with the exception
of;
'CachedOpenLimit' which has to do with caching of open files (you can
probably delete this one to return it to auto tuning)

'srvcomment' which you probably already knew is text that appears in the
Comment field next to the name of this computer in My Network Places



The shares should be saved in the \lanmanserver\Shares key. Here's a newer
article version for Windows XP but the text is virtually the same.

Hi. Please see below.

newer article version for Windows XP but the text is virtually the
same.

http://support.microsoft.com/kb/314498/EN-US/

That's newer? It's the exact same article I mentioned. I'm confused.
How is it newer?

The problem is that you can't follow step 6 in the KB article, not
knowing what "other static entries" you aren't supposed to delete. And
deleting everything except those items listed, at least on my XP Pro
system, killed all kinds of share-related things. (I don't think you're
supposed to delete the entry that lists a DLL name and path, for
example.)

http://support.microsoft.com/?kbid=125996

This article talks about saving and restoring individual share names and
permissions. Still, if you remove everything as described in 314498,
the entry "Sharing and Security" disappears from the context menu of a
local drive. This is a bad thing and is separate from what 125996 talks
about!

So the question remains how to restore auto-tuning if you have used the
command line to set autodisconnect to -1?

Thanks.

You're right it is the same article. I was looking at something else when I
typed that.

Very carefully.
