Exchange 2010 Outlook Anywhere proxy security certificate wildcard *.domain.com

When you use a wildcard certificate on your Exchange 2007 or 2010 environment you can receive an error on outlook:
There is a problem with the proxy servers's security certificate.
The name on the security certificate is invalid or does not match the name of the target site mail.domain.com
Outlook is unable to connect to the proxy server (Error code 0)

Error1
When using internally your outlook may connect just fine using the normal RPC-TCP method.
This happens because outlook is checking the name on the certificate for mutual authentication to ensure your are connecting to the right server. Outlook gets this information from the autodiscover service.
error2
If you manually change the value to msstd:*.domain.com it works, but the autodiscover will put the other value back in a matter of minutes. Autodiscover assumes a value equal to the external name set on your CAS server (in my case mail.domain.com) and uses this.

To override this behavior use the following exchange shell command:
Set-OutlookProvider EXPR -CertPrincipalName msstd:*.domain.com
After you adjust this, you need to restart the “world wide web publishing” service, because of caching.

You could also disable this “Mutual authentication”, but it’s a good security feature, so I wouldn’t.
Set-OutlookProvider EXPR -CertPrincipalName none
Remember to restart the W3P service.

Be aware that when you set $null instead of none Exchange will go back to default behavior and use the external name from the CAS server.

RDWeb shows no icons with Internet Explorer 10 TSWeb (server side fix)

RDWeb or TSWeb is the Microsoft Remote Desktop service web access page from Windows 2008 or Windows 2008 R2.

When using Internet Explorer 10 to browse to an RDWeb (>=2008 R2) or TSWeb (=2008) the icons for the published apps are missing or blank and WKSPRT.EXE (provides SSO) does not load. You have to click the compatibility icon in the browser and then it does work.

If you want to make sure that users don’t have to click compatibility mode, you can send the header to emulate IE9 from server side, so Internet Explorer automatically uses the right mode.

You can choose between 2 options (I prefer option2, easier and less work):

1) Edit all the *.aspx pages (except logoff.aspx) under the %windir%\Web\RDWeb\Pages\en-US\ folder.
Add <META HTTP-EQUIV="X-UA-COMPATIBLE" CONTENT="IE=9"> right below the lines <html><head id=”Head1″ runat=”server”>

2) Add the header in IIS for the RDweb so that it is automatically added to all pages served from RDweb.
Open IIS Management under Administrative tools in the start menu.
Expand the Default Web Site using the plus sign next to it. Click on RDWeb and then in the middle pane double click on HTTP Response Headers (under the IIS category). In the list with headers right click on the empty space and click Add. Under name fill in: X-UA-Compatible and under value fill in: IE=9

Exchange missing public folder database after adsiedit changes

I had to use Adsiedit.msc to manually remove the Public folder database on an Exchange 2007 i was trying to uninstall. I already had a new public folder database with all replica’s present on my Exchange 2010 server, so i was confident in removing the older Exchange 2007 PF database through Adsiedit. In the meantime I also removed the “First Administrative group” since this was left from Exchange 2003.

I then proceeded to uninstall Exchange 2007 without further issues.
I was surprised and horrified to find the Exchange 2010 Public Folder database missing in the “Database management tab” on “Organization – Mailbox” in the Exchange 2010 Management console. I tried various things, such as:
1) Restart information store
2) Recreate PF DB with exact same name, but this error saying it already had a DB with that name.

I ran the Best Practices Analyzer and it told me “Site folder server deleted”. I clicked on the help and it showed me how to fix this.

Open an Active Directory editor, such as ADSI Edit.
Locate the public folder information store that you want to designate as the Site Folder Server. For Exchange Server 2000 through Exchange Server 2007, expand the following nodes in the Configuration container:
CN=Configuration,DC=,DC=com, CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups, CN= CN=Servers, CN=, CN=InformationStore, CN=
For Exchange Server 2010, expand the following nodes in the Configuration container:
CN=Configuration,DC=,DC=com, CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups, CN=Exchange Administrative Group (FYDIBOHF23SPDLT), CN=Databases
In the right pane, right-click CN=, and then click Properties.
In the Attributes field, scroll down and select the distinguishedName attribute.
Click Edit, and then copy the entire attribute to the Clipboard.
Expand the Configuration container, and then expand CN=Configuration,CN=,CN=com, CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups
Right-click the administrative group you want to modify, and then click Properties.
In the Attributes field, scroll down and select the siteFolderServer attribute.
Click Edit, and then paste the value for the distinguishedName attribute into the Value field.
Double-check the contents of the Value field to ensure the paste was performed correctly, and then click OK to save the change.
Click OK to close the Administrative Group properties.
Exit the Active Directory editor and restart the Microsoft Exchange Server Information Store service on all Exchange Server computers in the site for the change to take effect.

I reran the BPA and the error was gone, but my PF database was still missing.
After some research on the internet I came by the solution thanks to “BFTech Impressions”.
Specifically in my case the “msExchOwningPFTree” attribute was empty on my PF database container and needed to be filled with the value from the “distinguishedName” attribute from the Public Folder container uner “Folder Hierarchies”, the first 2 steps in my case were not needed, these were still present.

Here is the link to the article:
http://blog.bruteforcetech.com/archives/766
Please click on the links for detailed instructions and screenshots.

These are his instructions I quote here so that in the case the original disappears the information is not lost.

Here are the instructions to fix it:
Open ADSI Edit, connect to a Domain Controller, change the context to Configuration.

Create the Folder Hierarchies under the Exchange Administrative Group
Navigate to Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ [your organization] ⇒Administrative Groups ⇒ [your administrative group]
Right click on your administrative group and select New Object
Select msExchContainer as class and click Next
Enter the following as value: Folder Hierarchies, click Next, Finish

Create the Public Folders Tree Object
Right click Folder Hierarchies and select New Object
Select msExchPFTree as class, click Next
Enter the following as value: Public Folders, click Next
Click on More Attributes button, drop down the “select a property to view” list, select msExchPFTreeType and set the attribute to 1 (it should populate into the value field).
Click OK, Finish

Populate the msExchOwningPFTreeBL attribute object of the PF Store
(Tell the Public Folder database where to find the new folder hierarchy you just created)
Double click the newly created “Public Folders” object
Double click distinguishedName, copy the value to the clipboard, click Cancel
Exchange 2007: open properties of Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ [your organization] ⇒ Administrative Groups ⇒ [your administrative group]⇒ Servers ⇒ [your server] ⇒ Information Store
Exchange 2010: open properties of Configuration ⇒ Services ⇒ Microsoft Exchange ⇒ [your organization] ⇒ Administrative Groups ⇒ [your administrative group] ⇒ Databases ⇒ [your Public Folder database]
Double click the msExchOwningPFTree attribute, paste the value that was copied to the clipboard in step 2
Click OK twice

Blackberry Enterprise Server Express MAPI client error

When running Exchange 2010 (my case SP3) make sure you install the “MAPI CDO 1.2.1 package”.
If you install this while setup was checking prerequisites, you might get an error later on while on the MAPI settings screen. Check Now resolves the besadmin account fine and changes the name to the SMTP address. But when clicking Next, you get an error.

The setup application could not initialize the Microsoft Exchange Server MAPI Client. Make sure that MAPI is installed and configured correctly and the Microsoft Exchange Server and mailbox that you specified are correct.

1) Make sure the User account is not hidden from the GAL, open the mailbox in exchange console and check on general tab.

2) Press cancel and rerun setup, it resumes from where you left off, and now it proceeds.

Exchange: Name Could Not be Matched to a Name in the Address List

English: “Name Could Not be Matched to a Name in the Address List”
Dutch: “Naam niet gevonden in de adreslijst”

Outlook showed this error while setting up the mailbox profile.
The user could login in to OWA without issues. In my case it had nothing to do with the Global Address List or Offline Address book.
Seems some attributes on the user in Active Directory were missing. In Exchange console i disabled the mailbox and thus removing exchange attributes from the user. The mailbox them became disconnected, and next I connected the mailbox again to the same user.

After that everything worked! If you have multiple AD sites remember that the Domain Controllers need time to sync.

6to4 isatp tunnel problem windows VISTA & 7

The PC or laptop may appear to be very slow and CPU is at 100% most of the time. When you check in taskmanager (after selecting show processes from all users) 1 or more svchost.exe processes are hogging CPU. When you right click the svchost.exe and choose “go to service” you find oud that it is 1 of the following services:
– wudfsvc
– DcomLaunch
– PlugPLay

Open up a Command prompt (type cmd in the start – search field) and type in ipconfig to see if there a lot of tunnel adapters present. Normally you see only 1 or maximum 4 and then a local area network and perhaps a wireless adapter. If you have dozens of tunnel adapters, then this bug is effecting you.

Too many tunnel adapters in IPCONFIG
Too many tunnel adapters in IPCONFIG

To solve this execute the following:
Open up a Command prompt (CMD) but right click to run as administrator.
Type (without the quotes): netsh int isa set state disabled
Leave the command prompt open.
Now open up device manager, go to view and select “show hidden devices”.
In the device list, go to network adapters and disable the “Toredo tunneling interface” and the “6to4 adapter”.
To remove the large amount of tunnel adapters you can use this batch file, thanks to: Ryan Victory.
Remove tunnel adapters Batch file download link
You extract the content and run as administrator (right click) the 6to4remover.bat file from the folder that corresponds to you OS architecture (32 or 64 bit).
If you get a popup asking to accept license terms for devcon.exe, accept it. Maybe you then have to run as administrator it again to start. When it’s started it will remove all excess adapters.

After these actions are complete reboot your system. It should be back to normal.

XFIRE: run game without UAC elevation

Xfire would launch the Call of Duty 2 with UAC elevation and then the game would error with “INVALID CD KEY”.
This is because Xfire would launch the game with UAC elevation. Some games need UAC elevation, but Call of Duty 2 not.
You can change this setting per game by opening:
C:\ProgramData\Xfire\xfire_games.ini

In this list search the specific game and change RunElevated=1 to RunElevated=0.
