Outlook Recurring meeting problem

by on Jan.14, 2010, under Windows Info

Shamelessly ripped from Slipstick: (thanks, guys)

If your Outlook seems possessed and turns all of your meeting requests into recurring meetings, you have a Dell laptop with MediaDirect.

There is a bug in the add-in that reads Outlook meetings so Media Direct’s Instant Office can display then without fully booting into Windows. You’ll need to uninstall it, or disable the add-in called “Outlook Setup Addin (Cyberlink)” to put an end to the errant recurring meetings.

Adding MIME types to IIS 6

by on Jan.05, 2010, under Windows Info

Recently, a client had issues with Office 2007 documents turning (supposedly) into .zip files.
Apparently, the .docx and .xlsx formats are actually compressed XML files, and when IIS doesn’t have a MIME type for them in the MIME map, it passes them through as .zip files. This is problematic, to say the least.
When this happens, you can run the following script against the web server, and add the necessary MIME types to the map.

The original article where the script was found is here.


' This script adds the necessary Office 2007 MIME types to an IIS 6 Server.
' To use this script, just double-click or execute it from a command line.
' Running this script multiple times results in multiple entries in the
' IIS MimeMap so you should not run it more than once.
' Modified from http://msdn.microsoft.com/en-us/library/ms752346.aspx

Dim MimeMapObj, MimeMapArray, MimeTypesToAddArray, WshShell, oExec
Const ADS_PROPERTY_UPDATE = 2

' Set the MIME types to be added
MimeTypesToAddArray = Array(".docm", "application/vnd.ms-word.document.macroEnabled.12", _

Windows Profile Utility

by on Dec.30, 2009, under Windows Info

Have you ever needed to move a workstation from one Active Directory domain to another, and retain all local user profile information for the new domain? It’s really a hassle. Sure, you can try Windows Easy Transfer, or File and Settings Transfer Wizard, but it’s a crap shoot as to whether or not it will work correctly… Recently, when a client’s SBS 2003 server died, and had to be replaced, a friend shared an *AWESOME* utility with me. (Thanks, Kevin.. I owe you one)
It’s called the “User Profile Wizard 3.0”, and is available for download from the fine folks at ForensIT here:
http://www.forensit.com/downloads.html
You can assign an old pre-existing profile to a new domain user, and the application handles all registry ACLs, SIDs, and can even join the new domain for you. You must have this tool in your arsenal, hurry and download before Microsoft buys it up.. :)

Connect SQL Studio Express to Windows Internal Database

by on Dec.20, 2009, under Windows Info

You can use SQL Studio Express to administer the Windows Internal database. Just point the SSE to:

\\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query

And Bob is your father’s brother. Also, I know that this is not news. It’s just easier to copy and paste, and I can always find it here. ;)

Using Psexec to silently install Firefox on multiple workstations

by on Sep.24, 2009, under Windows Info

Recently, I needed to install Firefox-3.5.3 on multiple workstations in an Active Directory domain. Rather than create MSI packages and assign the application with Group Policy, I used Psexec and batch scripts to push it out. Here’s how:
If you don’t have Psexec installed, you can download it from Microsoft here: http://technet.microsoft.com/en-us/sysinternals/bb896649.aspx
Next, download the installer you want to use. In this example, we’ll use Firefox. Make a share on your server that all users can read, and place the installer inside the share.
So now, we’ve got \SERVERNAMESHARENAMEFirefoxInstaller.exe
Next, you need a few files to make this happen:
1. UpdateClients.bat
2. hostnames.txt
3. SoftwareInstaller.bat
All of these files need to be in the same directory, and you must have administrative privileges on the workstation you wish to update.
Basically, the UpdateClients.bat file enumerates the hostnames.txt, and passes the hostnames of the workstations/servers found in it to the SoftwareInstaller.bat file. Here are the contents of the files:

1. UpdateClients.bat


for /f "tokens=*" %%a in (hostnames.txt) do SoftwareInstaller.bat %%a

2. hostnames.txt (one hostname per line)


hostname1
hostname2
hostname3

3. SoftwareInstaller.bat


SET SERVERNAME=replacewithservername
SET SHARENAME=replacewithsharename
echo "checking for Installers directory on the target..."
if not exist \%1C$installers mkdir \%1C$installers
if not exist \%1C$installersfirefox353 mkdir \%1C$installersfirefox353
echo "copying Firefox install to install directory..."
xcopy "\$SERVERNAME$SHARENAMEFirefoxInstaller.exe" "\%1C$installersfirefox353" /e /y
echo "Installing Firefox..."
psexec.exe \%1 "c:installersfirefox353Firefox353.exe" -ms
echo "Firefox Done."

Now, fill the hostnames.txt with your hostnames, and double-click UpdateClients.bat.

Recreating the Exchange 2007 OWA Virtual Directories

by on Aug.19, 2009, under Windows Info

Sometimes, too many people have messed with it.
Plain and simple.
People like to check boxes. And enable/disable things. it’s fun.
But when it’s your CAS server, it can be a real hassle to navigate the IIS interface, and reset all of those little “tweaks”, placed there by someone with apparently no business “tweaking” IIS.
You know who you are.
;P

In these cases, it’s much easier to let Exchange do it for you, and all you need to open is the Exchange Management Shell.

This will list all the current OWA-related virtual directories.

    get-owavirtualdirectory

This will delete the OWA virtual directory for the Default Web Site.

    remove-owavirtualdirectory -identity "owa (Default Web Site)"

This command will re-create the owa virtual directory under the Default Web Site in IIS.

    new-owavirtualdirectory -OWAVersion "Exchange2007" -Name "owa (Default Web Site)"

This command will re-create the “Exchange” virtual directory under the Default Web Site in IIS.

    new-owavirtualdirectory -OWAVersion "Exchange2003or2000" -VirtualDirectoryType "Mailboxes" -Name "Exchange (Default Web Site)"

When you run this command, if you get an error similar to the one below, it is possible that IIS is set to work in 32 bit mode and not the required 64 bit mode.

    New-OwaVirtualDirectory : An error occurred while creating the IIS virtual directory ‘IIS://mailserver.yourdomain.com/W3SVC/1/ROOT/owa’ on ‘mailserver’.
    At line:1 char:24
    + New-OWAVirtualDirectory <<<< -OWAVersion "Exchange2007" -Name "owa" -Website "Default Web Site"

To make IIS run in 64 bit mode, run the following in an administrative command prompt:

    cscript %SYSTEMDRIVE%inetpubadminscriptsadsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

THIS UPDATE WAS SHAMELESSLY RIPPED FROM http://my.opera.com/ravenoverride because if I have to spend another 2 hours searching for the correct command to add these to the proper site name, I’ll snap.

Remove-OWAVirtualDirectory -Identity “Owa (XXXXXXX)” -Confirm:$false
Remove-OWAVirtualDirectory -Identity “Exadmin (XXXXXXX)” -Confirm:$false
Remove-OWAVirtualDirectory -Identity “Exchange (XXXXXXX)” -Confirm:$false
Remove-OWAVirtualDirectory -Identity “Exchweb (XXXXXXX)” -Confirm:$false
Remove-OWAVirtualDirectory -Identity “Public (XXXXXXX)” -Confirm:$false
Remove-WebServicesVirtualDirectory -Identity “EWS (XXXXXXX)” -Confirm:$false
Remove-ActiveSyncVirtualDirectory -Identity “Microsoft-Server-ActiveSync (XXXXXXX)” -Confirm:$false
Remove-OabVirtualDirectory -Identity “OAB (XXXXXXX)” -Force:$true -Confirm:$false
Remove-UMVirtualDirectory -Identity “UnifiedMessaging (XXXXXXX)” -Confirm:$false
Remove-AutodiscoverVirtualDirectory -Identity “Autodiscover (XXXXXXX)” -Confirm:$false

To verify that the directories have been removed, run the following commands. You should receive no output:

Get-AutodiscoverVirtualDirectory
Get-OABVirtualDirectory
Get-OWAVirtualDirectory
Get-WebServicesVirtualDirectory
Get-ActiveSyncVirtualDirectory
Get-UMVirtualDirectory

To properly create these virtual directories, run the following commands (Please keep the information what you got earlier for XXXXXXX and change it here to):

– Open Exchange Management Shell with elevated permission
– Run the following commands (THE COMMANDS ARE A ONE-LINER. THE NEXT COMMAND IS SEPARATED WITH —————————–. So copy and paste it into notepad, check if it is one line, read it carefully and change the information you have to provide. Information you have to provide is in BIG LETTERS or XXXXXXX):

New-OWAVirtualDirectory -WebsiteName “XXXXXXX” -OwaVersion “Exchange2007”
-ExternalAuthenticationMethods Fba
—————————–

—————————–
Set-OfflineAddressBook “Default Offline Address Book”
-VirtualDirectories “ServernameOAB (XXXXXXX)” -Versions Version2,Version3,Version4)”

– To check if we were successful in creating the virtual directories correctly type in the commands:

Get-AutodiscoverVirtualDirectory
Get-OABVirtualDirectory
Get-OWAVirtualDirectory
Get-WebServicesVirtualDirectory
Get-ActiveSyncVirtualDirectory
Get-UMVirtualDirectory

For example, you should receive the following for Get-OWAVirtualDirectory

Name Server OwaVersion
——– ——- ———–

Owa (XXXXXXX) Server Name Exchange2007
Exadmin (XXXXXXX) Server Name Exchange2003or2000
Public (XXXXXXX) Server Name Exchange2003or2000
Exchweb (XXXXXXX) Server Name Exchange2003or2000
Exchange(XXXXXXX) Server Name Exchange2003or2000

– Then run the following commands to disable the Kernel Mode Authentication on EWS, Autodiscover, and OAB virtual directories (THE COMMANDS ARE A ONE-LINER. THE NEXT COMMAND IS SEPARATED WITH —————————–. So copy and paste it into notepad, check if it is one line, read it carefully and change the information you have to provide. Information you have to provide is in BIG LETTERS or XXXXXXX):

cd $env:windirsystem32inetsrv
—————————-
.appcmd.exe unlock config “-section:system.webserver/security/authentication/windowsauthentication”
—————————–
.appcmd.exe set config “XXXXXXX/ews” “-section:windowsAuthentication” “-useKernelMode:False” /commit:apphost
—————————–
.appcmd.exe set config “XXXXXXX/AutoDiscover” “-section:windowsAuthentication” “-useKernelMode:False” /commit:apphost
—————————–
.appcmd.exe set config “XXXXXXX/oab” “-section:windowsAuthentication” “-useKernelMode:False” /commit:apphost

– Run: iisreset /noforce

– You must rerun the Internet Address Management Wizard to stamp the new virtual directories with the proper external URL and maybe you have to check the certificates.

Resetting Registry Permissions on Windows XP

by on May.28, 2009, under Windows Info

First, you need to download SubInACL.

SubInACL is a command-line tool that allows administrators to obtain security information about files, registry keys, and services. It also allows you to transfer this information from user to user, from local or global group to group, and from domain to domain.

Next, create a file with the name regperms.cmd under C:Program FilesWindows Resource KitsTools folder

Now you need to Edit the regperms.cmd file and add the following lines

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f

Save and exit the file

Now, you need to open a command prompt and run the following command:

cd “C:Program FilesWindows Resource KitsTools”

After this, press enter and then run this command:

regperms.cmd

After entering this, press enter. After a few minutes of processing by subinacl, the permissions will be reset. Reboot, and enjoy!

Removing Symantec Corporate Antivirus with psexec

by on Mar.23, 2009, under Windows Info

Lately, I’ve been ripping out and replacing antivirus software in the Enterprise. Funny thing is, most of these types of software do not have a remote uninstall utility. Being the famously lazy admin I am, I had no interest in logging into each workstation, and manually removing it.

Instead, I used psexec. It’s just one command in an awesome toolset written by Mark Russinovich called Pstools. So, I saved the following as a batch file, and executed it against all domain workstations. Here’s the contents of the symantec_removal.bat file:


REM save this as c:symantec_removal.bat
@reg add HKLMSOFTWAREIntelLANDeskVirusProtect6CurrentVersionAdministratorOnlySecurity /v UseVPUninstallPassword /t REG_DWORD /d 0 /f
@reg add HKLMSOFTWAREIntelLANDeskVirusProtect6CurrentVersionAdministratorOnlySecurity /v LockUnloadServices /t REG_DWORD /d 0 /f
msiexec /norestart /qn /x{46B63F23-2B4A-4525-A827-688026BE5E40}

Then, just install pstools into your PATH, and open a command prompt on the server, and do this:

psexec \* -c c:symantec_removal.bat

You’ll notice that the msiexec command has a GUID, so if your version of Symantec is different than mine, you’ll need the correct GUID for your version. This can be found here:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall

Just look through the GUIDs located here until you find your version of Symantec. Then, just replace {46B63F23-2B4A-4525-A827-688026BE5E40} with the GUID found in your registry.

BTW – The first 2 lines in that batch file are for removing the uninstaller password from symantec antivirus. If you don’t use an uninstall password, you can remove them.

Detecting Symantec Uninstall password existence

by on Mar.16, 2009, under Windows Info

I wrote (swiped and altered) this script to check for a Symantec Uninstaller password. You might notice that it’s very similar to the Remote Desktop script I posted a while back. Still it works, and saves some time, so here it is:

symantec_uninstall_password_checker.bat
