Cannot display webpage after updating SSL Certificate

Check if the server certificate has the private key corresponding to it. Refer the below picture:

SSL Cert wo and wprivate key

If private key is missing, then you need to get a certificate containing the private key, which is essentially a .PFX file. There is a command that we could try to run in order to associate the private key with the certificate:

 C:\>certutil –repairstore my “‎1a 1f 94 8b 21 a2 99 36 77 a8 8e b2 3f 42 8c 7e 47 e3 d1 33”

 certutil repair

 Note: 1a 1f 94 8b 21 a2 99 36 77 a8 8e b2 3f 42 8c 7e 47 e3 d1 33 is the thumbprint of the certificate. Open the certificate and click on the details tab. Scroll down to find the thumbprint section. Select the thumbprint section and click on the text below. Do a “Ctrl+A” and then “Ctrl+C” to select and copy it. Below is a snapshot for your reference:

If the association is successful, then you would see the following window:

Windows server backup fails consistency check of the Exchange database

Trying to backup Exchange 2010 and purge transaction logs using the built-in Windows Server Backup app (Windows 2008).

– Backup completes but with warnings and log files won’t purge

-Found that the backup will run successful only if database files and the transaction log files on the same volume

Moved the transaction logs files via the EMC to the save volume as the databases and got past the consistency check failure issue, and got a good backup w/flushed logs.

Move WSUS SQL database to another location

When running WSUS on a Small Business Server, the default location is the C: drive, when that drive gets full you need to move the content and the SQL database. Below are the steps to move the SQL database to another location.

1. Open command prompt and type: net stop “update services”

2. Next, at the command promt type: net stop w3svc (if it is SBS 2008 it will also stop the Terminal Services Gateway, remember to restart)

3. Open Microsoft SQL Express Management Studio (if you don’t have this, go to to download) and connect to the MICROSOFT##SSEE database, which is the WSUS database and the SharePoint databases in SBS 2008. You can’t just connect to the database normally, you need to type this in server name area:   \.pipeMSSQL$MICROSOFT##SSEEsqlquery


 4. Detach the SUSDB database, move the SUSDB folder to the new location and attach the database again with Management Studio

5. Restart the services: “update services”, “w3svc”, and “Terminal Services Gateway”



Disable SSL v2.0 in IIS

While going through a vulnerability scan for PCI compliancy, the report noted that IIS 7 on a Small Business Server 2008 was still using SSL v2.0 instead of SSL 3.0 or TLS 1.0. To disable SSL v2.0:

  1. Click Start, click Run, type regedt32 or type regedit, and then click OK.
  2. In Registry Editor, locate the following registry key:HKey_Local_MachineSystemCurrentControlSetControlSecurityProvidersSCHANNELProtocolsSSL 2.0Server
  3. On the Edit menu, click Add Value.
  4. In the Data Type list, click DWORD.
  5. In the Value Name box, type Enabled, and then click OK.Note If this value is present, double-click the value to edit its current value.
  6. Type 00000000 in Binary Editor to set the value of the new key equal to “0”.
  7. Click OK. Restart the computer.

IIS negotiates the encryption with the client browser. An attacker could use a tool that tells the server it has only sslv2 (which is weaker) available. If you disable sslv2 it only uses v3 or tls, as requested by browser. A browser only supporting sslv2 would fail.

 This applies to Windows Server 2003, and Windows Server 2008, and both versions of SBS.;en-us;187498

Change default behavior for unidentified network in Vista/Windows Server 2008/Windows 7

I ran into an issue with a Hyper-V server with 6 NIC’s, some of the NIC’s in Network and Sharing center were being categorized as ‘unidentified network’ and giving the public designation. I could change it to private, but every reboot it would revert back. The issue with public network was that network discovery and file sharing was turned off, so even the NIC that was joined to the domain had little connectivity. Below fixed the issue.

You can change the security setting so that the network is not made public in the first place.

To do this on your local server or Vista/Windows 7 desktop , follow these steps:

1. Start –> run –> MMC –> press enter

2. In MMC console , from menu file select Add/Remove Snap-in

3. Select Group Policy Object editor –> Press Add –> select Local computer –> press OK –>press OK

4. Open Computer configration –>Windows Settings –>Security Settings –>select Network list manager policies
on the right Side you will see options for :

double click –>Unidentified networks

  Then you can select the option to consider the Unidentified networks as private and if user can change the

Sending email to certian domains does not work when you run Exchange Server 2007 on a Windows Server 2008-based computer

You may have trouble sending mail to certain domains while using Exchange Server 2007 on Windows Server 2008. The Queue Viewer displays the following status error for the domain in question:

“451 4.4.0 primary target IP address responded with “421.4.4.2 unable to connect.”attempted failover to alternate host, but that did not succeed.Either there are no alternate hosts, or delivery failed to all alternate hosts.”

This problem occurs because routers do not support the TCP autotuning settings in Windows Server 2008.

To disable autotuning, follow these steps:

Run CMD as Administrator

At the command prompt, type the following command, and then press ENTER:

netsh interface tcp set global autotuninglevel=disabled

This command disables the Receive Window Auto-Tuning feature.

Exit the Command Prompt window.

Restart the computer.
