Does anyone have the Hotfix described in KB818528. Is there anyway to
obtain it without calling Microsoft???

Terminal Services Shared File Bug Fix
The network redirector mrxsmb.sys creates one data structure per computer
for every user that accesses a shared file on a Win2K system. The redirector
per-computer data structure causes problems when a Win2K system is
configured as a Win2K Server Terminal Services server and multiple Terminal
Services clients access the same file. To properly maintain connection
information, the redirector needs one data structure for each client
session. In the current implementation, when two or more Terminal Services
clients open the same file and one of the clients closes the file, the
redirector incorrectly closes the connection for all Terminal Services
clients. You can find documentation about the unexpected behavior in two
Microsoft articles: "Programs Run from Network Share on TS Close or Generate
Errors" (http://support.microsoft.com/?kbid=294816) and "PRB: 'Error reading
file' Error Message on Windows 2000 Terminal Services"
(http://support.microsoft.com/?kbid=299603). Microsoft now has a permanent
solution for this problem, which exists in all versions of Win2K through
SP4. Call Microsoft Product Support Services (PSS) and ask for the June 4
version of the redirector components mrxsmb.sys and rdbss.sys. These new
components have an option you can enable to create data structures on a
per-user, rather than a per-computer, basis. On Terminal Services servers,
after you install the new redirector, you need to activate the per-user data
structure feature by modifying the registry. Locate the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRxSmb\Parameters
registry subkey, and add the value entry MultiUserEnabled:REG_DWORD: 1 in
the right pane. Note that this modification is unnecessary on Win2K systems
that aren't configured as Terminal Servers. For more information about this
problem and solution, read the Microsoft article "Problems When More Than
One User Accesses the Same File Through Terminal Services"
(http://support.microsoft.com/?kbid=818528).
Major Citrix Logon Delays on SP4 Systems
When you use a Citrix client to connect to a Win2K SP4 system running Citrix
MetaFrame or Citrix 1.8 installation, plus Terminal Services, clients might
wait for 5 to 30 minutes for the desktop to appear. This problem occurs only
for clients running the ICA protocol and connecting to a Win2K system on
which you have redirected printing to a local printer on the client system.
PSS has a bug fix that solves this problem--updates to 12 files, most of
which have a file release date of July 17. When you call PSS, cite the
Microsoft article "Very Long Logon Time When You Try to Connect to Citrix
MetaFrame or Citrix 1.8" (http://support.microsoft.com/?kbid=824309) as a
reference.

What's keeping you from getting more from your terminal servers? Did you know,
in most cases, CPU Utilization IS NOT the single biggest constraint to scaling
up?! Get this free white paper to understand the real constraints & how to
overcome them. SAVE MONEY by scaling-up rather than buying more servers.
