How to Convert Windows Server 2008 to a Workstation

Michael Khanin Michael Khanin Profile: Michael Khanin

Few last months I’ve been using Windows 2008 Server as a main OS on my laptop. It’s so stable 🙂 ,… Nothing will move me back to Windows XP or Vista, but to “convert” Windows Server 2008 to a Workstation is necessary to do few changes :).

One of the best (IMHO) explanations about “How to convert your Windows Server 2008 to a Workstation” could be found on

Outlook Web Access (OWA) on Apache in DMZ ;)

Michael Khanin Michael Khanin Profile: Michael Khanin

Using Apache 2 with Outlook Web Access (OWA) it’s very easy. This solution is even working when Apache installed on Windows XP and this solution can save a lot of money :), not necessary to buy Windows Server, additional Exchange Server licence or ISA Server. First, we need to enable some useful modules:


Now, we need to edit / create a VirtualHost section (or use Include conf/extra/httpd-vhosts. conf, remember to make following changes inside httpd-vhosts. conf ):

DocumentRoot /var/www/html/exchange
RedirectMatch ^/(index.html?)$
RedirectMatch ^/exchange$

# This secures the server from being used as a third party
# proxy server
ProxyRequests Off

# Allows the proxying of a SSL connection
SSLProxyEngine On
ProxyVia On

DocumentRoot /home/user/mail_proxy/html/
RequestHeader set Front-End-Https “On”

ServerName mail

# Set up SSL to work with this host
SSLEngine On
SSLCertificateFile /etc/apache/webmail-proxy/server.crt
SSLCertificateKeyFile /etc/apache/webmail-proxy/server.key

SSLProxyMachineCertificateFile /etc/apache/webmail-proxy/certnew.cer

ProxyPass /exchange/ https://mail-internal/exchange/
ProxyPassReverse /exchange/ https://mail-internal/exchange/

ProxyPass /exchweb/ https://mail-internal/exchweb/
ProxyPassReverse /exchweb/ https://mail-internal/exchweb/

ProxyPass /public/ https://mail-internal/public/
ProxyPassReverse /public/ https://mail-internal/public/

ProxyPreserveHost On

NOTE: If you are using Apache on Windows, remember to make changes accordingly.

How to Block Users from Sending Email Outside your Exchange Organisation

Michael Khanin Michael Khanin Profile: Michael Khanin

We can configure Exchange to prevent users from sending mail to the Internet (and receive mails). The user can only receive e-mail from other Exchange users in the same organization. To set this, follow the following steps:

  1. Create a new distribution group (mail-enabled) in Exchange.
  2. Add all the users which are not allowed to send mail outside your organisation.
  3. Modify (properties) the SMTP connector(s) that are used to send to the internet
  4. Under the Delivery Restrictions tab, REJECT MESSAGES FROM, add the distribution group.
  5. Start Registry Editor (Regedt32.exe).
  6. Locate and click the following registry key:
  7. On the Edit menu, click Add Value, and then add the following registry value:
    Value Name: CheckConnectorRestrictions
    Data Type: REG_DWORD
    Radix: Hexadecimal
    Value: 1
  8. Quit Registry Editor.
  9. Restart the Microsoft Exchange Routing Engine service and the Simple Mail Transfer Protocol (SMTP) services for this change to take effect.

Exchange System Manager (ESM) Crashs If Installed Internet Explorer 7 (IE7)

Michael Khanin Michael Khanin Profile: Michael Khanin

Over Internet you can find a lot of articles talking about one thing – NOT TO INSTALL IE7 on server machines :).
One of the reasons is a crash of Exchange System Manager (ESM).

Exchange System Manager (ESM) crashes when you press F1, or click on the Help menu option.
As result, inside Event Viewer you will see an Event ID 1000.

I really don’t want to recommend you uninstall IE7. The solution for this “issue” is very simple, remove (rename) the PSAPI.DLL from the Exchsrvr\bin subdirectory:

  1. Stop the Exchange System Attendant Service
  2. Stop the IIS Admin Service
  3. Open a Command Prompt rename the PSAPI.DLL in the exchsrvr\bin directory. to PSAPI.DLL.OLD
  4. Restart the Exchange and IIS services.
  5. Enjoy 🙂

Michael Khanin Michael Khanin Profile: Michael Khanin

The RSM (Removable Storage Management) requires to manually manage media, when performing a NTBackup.
I would like to show a script, that allows to forget about this (DO NOT FORGET TO CHANGE TAPEs ; ) )

Here is a script:

@echo Off
RSM.exe refresh /LF”Hewlett Packard LTO Ultrium-3 drive”
@Echo Please Wait…

ping -n 11 > null

for /f “Tokens=1-4 Delims=/ ” %%i in (‘date /t’) do  set dt=%%i-%%j-%%k-%%l
for /f “Tokens=1” %%i in (‘time /t’) do set tm=-%%i

set tm=%tm::=-%
set dtt=%dt%%tm%

C:\WINDOWS\system32\ntbackup.exe backup “@C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\Daily_Backup.bks” /n “EPIC001 %dtt%” /d “EPIC001 %dtt%” /v:no /r:no /rs:no /hc:on /m normal /j “%dtt%” /l:s /p “LTO Ultrium” /UM
