VMware template for Windows Server 2008 R2

Great step by step for making a VM template

All mailboxes in an Exchange database are disconnected and/or your account has been disabled in OWA

This was for an issue which occurred on Exchange 2010 sp3 rollup 5.

Email flow had been working for years.  All of a sudden email flow stopped. Email server was restarted and email flow worked only for mailboxes located in one  specific Exchange database.  Mailboxes located in the other Exchange databases didn't have total email flow.  Mailboxes of affected users were unable to open Outlook.

When a working mailbox sent an internal email to an affected mailbox they would receive an undeliverable bounce back with the following message:
"Delivery has failed to these recipients or groups". "There's a problem with the recipient's mailbox. Please try resending this message. If the problem continues, please contact your helpdesk."

OWA was up but any mailbox in an affected database would receive a message "Your account has been disabled".  Among some of the details of the error message was:
Exception type: Microsoft.Exchange.Data.Storage.AccountDisabledException
Exception message: Cannot open mailbox

The issue stems from an Active Directory issue which caused the Exchange server to either get out of synch or to be caching information and not updating.  Below is how the issue was resolved.

Steps summary:

1. Try to reconnect disconnected mailboxes.
2. Check DNS server Exchange is using. (Note that this might not be a necessary step but it was part of resolution)
3. Clean Exchange database.
4. Fix any mailboxes stuck in Disconnect Mailbox folder.

Steps detail:

1. Try to reconnect disconnected mailboxes.

In Exchange Management Console (EMC) navigate to Microsoft Exchange -> Microsoft Exchange On-Premises -> Disconnected Mailbox.
Right click Connect.
Choose matching user.
Click OK.

2. Check DNS server Exchange is using

In Exchange Management Console (EMC) navigate to Microsoft Exchange -> Microsoft Exchange On-Premises -> Organization Configuration.
Right click and select "Modify Configuration Domain Controller"
Select Specify a domain controller
Domain = the domain the Exchange server resides on.
Configuration domain controller = make note of current selection and then choose a secondary domain controller.
Click OK.
Repeat above steps but this time Configuration domain controller = the original or primary domain controller.
Click OK

3. Clean Exchange database

In Exchange Management Shell (EMS) run the following cmdlet

Get-Mailboxdatabase

Make note of any database listed under Name column

Now run the following cmdlet. Replace the "DBNAME" with the database name from above. Run the cmdlet on each database.

Get-Mailboxdatabase –Identity “DBNAME” | Clean-Mailboxdatabase

4. Fix any mailboxes stuck in Disconnect Mailbox folder

In Exchange Management Console (EMC) navigate to Microsoft Exchange -> Microsoft Exchange On-Premises -> Disconnected Mailbox.
Click Refresh.
If any mailbox is still listed, right click and select Connect.
Choose matching user.
Click OK.

Bonus step that was not performed but might be necessary.
If mailbox does not appear after replication, Run Get-Mailboxdatabase | Clean-Mailboxdatabase.

How to remove/delete old updates on WSUS server

This How-To is designed to show you how to most effectively clean your WSUS server of old, depreciated or superceded updates. This how-to assumes that you have already selected the correct update classifications, products, and languages for your environment. If you still need to do that, see this How-To here: http://community.spiceworks.com/how_to/show/2572

1.	Open the Windows Update Services MMC
2.	Select the All Updates View Set the display to show the Approval status of 'Any except Declined' with a Status of 'Any'. Click Refresh.
3.	Display the Supercedence Column Right-click the column headers and select Supercedence.
4.	Sort by Supercedence Left-click on the Supercedece Column.
5.	Select and Decline the Superceded Updates The updates to be declined have one of two particular flowchart symbols for their updates pictured in the attached image. Select the correct updates and Decline them by either right-clicking the selected updates and clicking decline or by pressing the decline button in the action pane.
6.	Run the Server Cleanup Wizard Make sure you have all options selected in the wizard and let it run. It will delete the files from the declined updates.
7.	OPTIONAL: Automatic Approval Options In the automatic approval options, under the advanced tab, there is an option to automatically approve update revisions for previously approved updates and subsequentially decline the now expired updates. I suggest you select them.

Unable to remove or disconnect network drive

 

When trying to disconnect a network drive the following error message is presented

“This network connection does not exist"

or

"Z:\ refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location.”

Perform the following steps to correct:

Run->Start
Regedit

Navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints
In this folder, delete anything with ## in front of it.

Run Task Manager
On Processes tab, highlight Explorer and click End Process
File->New Task (Run…) and type
Explorer

Below is a possible script to automatically fix the registry.  Save the following as .vbs

identify subkeys with "##" and remove them

const HKEY_CURRENT_USER = &H80000001
strComputer = "."
 
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")
 
strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2"
oReg.EnumKey HKEY_CURRENT_USER, strKeyPath, arrSubKeys
 
For Each subkey In arrSubKeys
    If CBool(Instr(subkey,"##")) Then
        oReg.DeleteKey HKEY_CURRENT_USER, strKeyPath&"\"&subkey
    End If
Next

Configuring Two Sonicwalls To Use Layer 2 Connection with Failover

This is a summery of how you can connect a layer 2 (point to point/direct connection) between two Sonicwalls using SonicOS Enhanced 5.8.  This is also a summery of how you can use the second Sonicwall’s WAN as a failover connection for the first Sonicwall.

On the first Sonicwall, plug layer 2 connection into an interface.  For this example we will use X5.

Network->Interfaces
   
    Zone: WAN
    IP Assignment: Static
    IP Address: 10.10.10.1
    Subnetmask: 255.255.255.0
    Default Gateway: 10.10.10.2
    DNS Server 1: 208.67.222.222
    DNS Server 2: 8.8.8.8
    DNS Server 3: 208.67.222.220

On the second Sonicwall, plug layer 2 connection into an interface.  For this example we will use X5.

Network->Interfaces

    Zone: LAN
    Mode/P Assignment: Static IP Mode
    IP Assignment: 10.10.10.2
    Subnetmask: 255.255.255.0

For failover and the ability to use the second Sonicwall's WAN for the first Sonicwall's WAN...
On the first Sonicwall

Network->Failover & LB

    Check Enable Load Balancing
    Check Respond to Probes

    In the Groups section Click Configure for Default LB
        Type: Basic Failover
    Check Preemp failback to preferred interfaces when possible
    Highlight X5 interface and click Add
    Order desired interface and click OK

    Click Configure for X5
        Select Logical/Probe Monitoring enabled
        Select Probe succeeds when either Main Target or Alternate Target responds
        Main Target: Ping (ICMP) Host: 4.2.2.1
        Alternate Target: Ping (ICMP) Host: 8.8.8.8
        Default Target IP: 208.67.222.222
        Click OK
    Click Accept
