Autodiscover and/or EWS unavailable on Exchange 2007/2010

Symptom: Outlook crashes or you cannot access OutOfOffice settings after you install a package that contains the .NET Framework 3.5 with SP1 and the .NET Framework 2.0 with SP2 on an Exchange 2007 or on an Exchange 2010 server (CAS role)

Problem described in:

My solution:

Turn of any mmc, powershel console, emc etc.

Uninstall .net 3.5 sp1
Uninstall .net 3.0 sp2
Uninstall .net 2.0 sp2

In this order, without restarting!
if it complains that "you can't uninstall, some other package depends on it", do this:

net stop MSExchangeTransportLogSearch /yes
net stop MSExchangeTransport /yes
net stop MSExchangeServiceHost /yes
net stop MSExchangeSearch /yes
net stop MSExchangeRepl /yes
net stop MSExchangePop3 /yes
net stop MSExchangeMailSubmission /yes
net stop MSExchangeMailboxAssistants /yes
net stop MSExchangeIMAP4 /yes
net stop MSExchangeFDS /yes
net stop MSExchangeSA /yes
net stop MSExchangeEdgeSync /yes
net stop MSExchangeAntispamUpdate /yes
net stop MSExchangeADTopology /yes
net stop MSExchangeIS /yes
ping -n 5 -w 1000 >nul
net stop w3svc /yes

If you still can't uninstall, use procexp's "find" feature and close any .NET handle still open.

At the end there should be no reference to .NET in the installed programs.

Install .net 3.0 (I used version 3.0.4506.30 downloaded in 2008 an forgotten on server...)

[PS] Remove-AutodiscoverVirtualDirectory -Identity "EXCHANGE2007\Autodiscover (Default Web Site)"
[PS] New-AutodiscoverVirtualDirectory
[PS] Set-ClientAccessServer -Identity "EXCHANGE2007" -AutoDiscoverServiceInternalUri https://exchange2007.domain.tld/autodiscover/autodiscover.xml
[PS] Test-OutlookWebServices | fl

If you receive Error 401 when attempting to run Test-OutlookWebServices | FL, disable the loopback check in  HKLM\SYSTEM\CurrentControlSet\Control\Lsa  "DisableLoopbackCheck" DWORD, 1

- In IIS Manager make sure ASP.NET 2.0.50727 is ENABLED
- In IIS Manager make sure Autodiscovery and EWS uses only "Integrated windows authentication" and that the security cert is "require ssl", "128 bit" and "ignore client certificates"

- Verify that the folder %ExchangeInstallaDir%\ClientAccess\Autodiscover is readable by "authenticated users"
 - perform iisreset /noforce

[PS] Test-OutlookWebServices | FL should give you a good answer now, if not, make sure the autodiscover DNS entry exists:

- in DNS Manager rightclick the local forward lookup zone, "Other new records", "SRV", service "_autodiscover", pri "10", weight "5", port "443", host "autodiscover.domain.tld"
- in DNS Manager, new A-Record "autodiscover.domain.tld"

[PS] Test-OutlookWebServices | FL should give you a good answer now, if not, get the backup tape, it's that time...

Space "Magically" missing on Win 2012 drives

An apparently (almost) empty drive might show low space but looking at the files found that only a few GB was being consumed. Upon checking on the drive turned on show hidden on the server in a folder called System Volume Information.

The System Volume Information folder is a hidden system folder that the System Restore tool (XP, Vista/7/8) uses to store its information and restore points, it is also used by shadow copies for  backups and other purposes on Windows 2003/2008 and 2012. There is a System Volume Information folder on every partition on your computer.

So how do you reclaim the space? Well there are two ways either through the GUI or the command line to recover space that system restore is not using. Special Note: if you do this on SQL servers it will stop the MSSQL service.

CLI Method

Open a command prompt with the “Run as Administrator” option. Type in vssadmin list shadowstorage

As you can see the output shows used Space, Allocated Space and Maximum Space.

We can also see what available restore information is available by running vssadmin list shadows

So now let’s get to reclaiming the space on one of the drives. In the issue I had with disappearing space was with the F:\ drive. So to reclaim it I want to resize the maximum allocated space setting to 1 GB. The syntax is:

vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]

For Example:

vssadmin resize shadowstorage /on=F: /For=F: /Maxsize=1GB

To validate the changes took run vssadmin list shadowstorage.

Repeat the steps to make the changes to other drives and the space will be recovered.

GUI Method

Double click on Computer to see your drives. Right click on the drive in question and select Properties. Click on the shadow copies tab.

Select the drive in the list and click on the settings button. Check the Use Limit box and type in the amount in MB to which you want to set (1024 for 1GB) and click OK. Repeat for other drives until completed.

You are all done and now have more space.

Boot parameters for SCO6 on HP Gen8 servers (officially unsupported)

Install an extra P400 controller and connect the drives cage to it. Do not disable the on-board i400!
Install an extra E1000 dual NIC, as the onboard BCMs are not recognized by the kernel.

In BIOS, switch the sata controller to ahci and boot.

The following parameters allow you to boot and install OSR6 on Gen8:

After the installation is done, only USE_XAPIC=Y have to be added to /etc/default/boot.
