While installing “ownCloud” web services, the post installation checklist noted that WebDAV services did not appear to be enabled, check configuration instructions.  Consequently, the installation would not conclude.

I googled and found the above article and proceeded to enable each LoadModule and the Include for httpd-dav.conf file as shown in Step 1. Load WebDav in Apache Server, and Step 4. Restart the Apache Service.   It was unnecessary to perform  steps 2, 3, and 5 shown in the article.

STEP 1. Load WebDav In Apache Server. WebDAV comes with Apache server 2.x, you just need to enable it. Edit “%APACHE_PATH%/conf/http.conf“, un-comment the following load and include statements by removing the leading # hashtags.  Use Notepad++ to edit the file: http.conf

LoadModule alias_module modules/mod_alias.so
LoadModule auth_digest_module modules/mod_auth_digest.so
LoadModule authn_file_module modules/mod_authn_file.so
LoadModule dav_module modules/mod_dav.so
LoadModule dav_fs_module modules/mod_dav_fs.so
LoadModule dav_lock_module modules/mod_dav_lock.so
LoadModule setenvif_module modules/mod_setenvif.so

# Distributed authoring and versioning (WebDAV)
Include conf/extra/httpd-dav.conf

Before installing Zpanel on Windows Server 2008 R2 SP1, there are several prerequisites shown in the Zpanel installation instructions.  More precisely, there are several prerequisites to install before using the Zpanel install script to install and configure the WAMP Stack (Apache, MySql, and PHP) on the Windows Server.

FIRST: Install or Enable .Net Framework 3.5.1 which must be done by enabling the “FEATURE” of .Net Framework 3.5.1 rather than downloading it from Microsoft.  Here are the instructions to enable this Feature.  Why is it necessary to enable rather than install this version of .Net Framework? Because the executable installation file will not install.  Version 3.5.1 of .Net is already included as a “Feature” in Server 2008 R2.  To install it, you must merely enable this Feature from the server.

NEXT: The Zpanel installation instructions tell us to download and install the latest Visual Studio C++ 2010 Redistributables for your own particular OS (either x86 32bit or x64 64bit architechture).  This is not necessarily correct, but hold that thought for now. Also, there is an additional installation file that Zpanel Instructions offer, which contains several 2005, 2008 and 2010 Visual Studio C++ Redistributables for both x86 and x64.  Running this file seems to install all the necessary .dll files for those various VS C++ Redistributables. However, there may be a missing version regarding 2005.  Hold that thought too.

It appears that the Zpanel uses one of the 2008 x86 32bit disbributables and corresponding.dll’s for purposes of the PHP version 5.3.20 and/or Apache web server version that is installed by the Zpanel stack script.

After installing Zpanal, when you access the zpanel admin console and select “Server Admin” and select “PHP Info” you will find something like this:

PHP Version 5.3.20

System (Windows Whatever Version)
Build Date (And Whatever Build date it is)
Compiler MSVC9 (Visual C++ 2008)
Architecture x86
Configure Command cscript /nologo configure.js “–enable-snapshot-build” “–disable-isapi” “–enable-debug-pack” “–without-mssql” “–without-pdo-mssql” “–without-pi3web” “–with-pdo-oci=C:\php-sdk\oracle\instantclient10\sdk,shared” “–with-oci8=C:\php-sdk\oracle\instantclient10\sdk,shared” “–with-oci8-11g=C:\php-sdk\oracle\instantclient11\sdk,shared” “–enable-object-out-dir=../obj/” “–enable-com-dotnet=shared” “–with-mcrypt=static” “–disable-static-analyze”
Server API Apache 2.4 Handler Apache Lounge
Virtual Directory Support enabled
Configuration File (php.ini) Path C:\Windows
Loaded Configuration File C:\zpanel\bin\php\php.ini

However, NSLOOKUP from the Windows Command line was not working and the zpanel BIND and DIG were not working properly.

Upon running NSLOOKUP from the windows command line, the error message seemed to indicate a cross dependence error of some sort.

Running NSLOOKUP from the windows command line yielded a SideBySide error in the Event Viewer Application Log, as follows:

The win32 version 8.0.50727.6195 of the .DLLs of the 2005 C++ redistributable that must be downloaded, run and installed to fix the problem is located HERE: “Microsoft Visual C++ 2005 Service Pack 1 Redistributable MFC Security Update.”

When you click the Download Link, you must choose one of three files to download:

Choose the download you want
File NameSize

• vcredist_x86.EXE 2.6 MB (CHOOSE THIS ONE TO INSTALL)
• vcredist_IA64.EXE 6.3 MB
• vcredist_x64.EXE 3.0 MB

If you lookup Knowledge Base KB2538242 from Google or the Microsoft Support Site, then this will reveal the matching / missing version 8.0.50727.6195 and the link to where to download the correct “vcredist_x86.exe” (NOT vcredist_x64.exe).  You are given a choice of 3 different vcredist.exe files to download and install.  Choose the x86 (32bit) version regardless of whether your Win server’s operating system is x86 (32bit) or x64 (64bit).  Here is why:

IT DOES NOT MATTER WHETHER YOUR WIN OS IS 64-BIT.  IT MATTERS WHAT BUILD OF VISUAL STUDIO WAS USED TO CREATE THE PARTICULAR ZPANEL APPLICATIONS, AND IF THE AUTHOR BUILT 32-BIT APPLICATIONS, THEN TO RUN THAT 32 BIT APPLICATION IT REQUIRES THE PARTICULAR 32-BIT DLL’S SHOWN IN THE VISUAL STUDIO ASSEMBLY MANIFEST.

How to install .Net framework 3.5.1 on Server 2008 or Server 2012

NOTE: Installing the .Net framework 3.5.1 on Windows Server 2008 or Windows Server 2012 is a very easy process, but can be difficult to find.

2. Go to the “Featured” section in 2008, or “page” on 2012.
3. Locate and select “.Net Framework 3.5.1” from the list and check the box beside it.
4. Click “Next” and let it install.

Follow this link for the Latest stable release (10.1.0) of Zpanel

Prior to installing ZPanel on a Microsoft Windows based machine you must first ensure you have installed all recent versions of the Microsoft Visual Studio Runtime, ZpanelCP.com has provided all the required runtime installers for both 32 bit machines and 64 bit machines (use the links to download from our site!)

Installers for Microsoft Windows

• Application Stack (Apache, PHP, MySQL etc.) Installer for Microsoft® Windows™
• ZPanel Installer (installs ZPanel on top of the Application stack)

Pre-Installation Checklist

1. You MUST have a CLEAN, FRESH install of Windows (any version XP and above)
2.  You MUST have a domain name registered and pointing to your server computer IP
3. ZPanel should be installed and setup on a SUB-DOMAIN of your main domain: During installation you will be asked to enter an FQDN. This is the sub-domain zpanel is to be installed on. Examples: zpanel.domain.com, cp.domain.com, panel.domain.com, etc.
4. You MUST have opened and forwared the requireds ports in your modem or router, and on the server firewall. See the list of required ports here.

Windows server 2012 specifics

• do a fresh install of windows.
• if not set automatically (often in datacenter), set your static IP
• do all windows updates (may need to be launched a few times!)
• install .NET Framework 3.5 and redo updates
• go to http://www.microsoft.com/en-us/download/details.aspx?id=5555, download and install
• reboot windows and then install zpanel, as below:

Installing ZPanel 10.1.0 on Windows

It requires 3 steps :

1. Install Microsoft Visual C++ Runtime libraries:

• For Windows 32bit: VC10 SP1 vcredist_x86.exe
• For Windows 64bit: VC10 SP1 vcredist_x64.exe

2. Install the Application Stack (Apache, PHP, MySQL etc.) Installer for Microsoft® Windows™ -> Download link
3. Run the ZPanel Installer (installs ZPanel on top of the Application Stack) -> Download link

Each step requires that the previous steps have been completed with success first.

ZPanel does not setup any firewall to leave you the choice to select which you want and because it is far different under Linux and Windows.

You have to open these ports to enable the default configuration of ZPanel to work:

20 & 21 : FTP
25 (TCP) : SMTP
53 (TCP & UDP) : DNS
80 (TCP & UDP) : HTTP
110 : POP3
143 : IMAP
Optional:
If you have already setup (or will setup soon) SSL, you have to open also: 443 : HTTPS

If you use Windows RDP you should open 3389.
