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

Outlook Archive Using Received Date Instead of Modified Date

By default, Microsoft Office Outlook archives different items based on the item type:

• Email message: The received date or the last modified date and time, whichever is later.
• Calendar item: The last modified date and time or the actual date that an appointment, event, or meeting is scheduled for, whichever is later.
• Task: The completion date or the last modified date and time, whichever is later. Tasks that are not marked as completed are not archived. Tasks that are assigned to other users are archived only if the status is completed.
• Note: The last modified date and time.
• Journal entry: The date when the journal entry is created or the last modified date and time, whichever is later.
• Contact: Not archived.

After you create and configure the ArchiveIgnoreLastModifiedTime registry value, Outlook archives different items based on the following conditions:

• Email message: The received date.
• Calendar item: The actual date that an appointment, event, or meeting is scheduled for.
• Task: The completion date. Tasks that are not marked as completed are not archived. Tasks that are assigned to other users are archived only if the status is completed.
• Note: The last modified date and time.
• Journal entry: The date when the journal entry is created.
• Contact: Not archived.

 
Save the following to a .reg file and then double click the file to automatically add the entries to your registry.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences]
"ArchiveIgnoreLastModifiedTime"=dword:00000001
