To assign the disk-drive device name E: to the Letters shared directory on the \\Fin server, type:

net use e: \\fin\letters

To assign (map) the disk-drive device name M: to the directory Mike within the Letters volume on the \\Fin NetWare server, type:

net use m: \\fin\letters\mike

To connect the user identifier Dan as if the connection were made from the Accounts domain, type:

net use d:\\server\share /USER:Accounts\Dan

To disconnect from the \\Fin\Public directory, type:

net use f: \\fin\public /DELETE

To connect to the resource memos shared on the \\Fin 3 server, type:

net use k: “\\fin 3″ \memos

To restore the current connections at each logon, regardless of future changes, type:

net use /PERSISTENT:yes

Use a PowerShell script to find the 32 or 9 largest files and determine how many gigabytes they add up to. I am actually going to present you with three PowerShell scripts. Each is useful on its own; however, number 3 is the most useful.

1. Run:

Get-ChildItem c:\temp -recurse | Sort-Object length -descending | select-object -first 32 | ft name,length -wrap –auto

This command will return the file names and the size of the files in bytes. Useful if you want to know what 32 files are the largest in the Replicated Folder so you can “visit” their owners.

2. Run:

Get-ChildItem c:\temp -recurse | Sort-Object length -descending | select-object -first 32 | measure-object -property length –sum

This command will return the total number of bytes of the 32 largest files in the folder without listing the file names.

3. Run:

$big32 = $foo = Get-ChildItem c:\temp -recurse | Sort-Object length -descending | select-object -first 32 | measure-object -property length –sum

$big32.sum /1gb

This command will get the total number of bytes of 32 largest files in the folder and do the math to convert bytes to gigabytes for you. This command is two separate lines. You can paste both them into the PowerShell command shell at once or run them back to back.

Now here are some commands that you could use in the Command Prompt console in administrator mode in order to view and resize the space allocated for SVI “system volume information”:

1. To see the space allocated and used for SVI:

- Open Command Prompt with “Run as Administrator” option

- Type in: vssadmin list shadowstorage

- You will see Used Space, Allocated Space and Maximum Space for SVI

2. To see the restore information stored therein:

- Use in the same console command: vssadmin list shadows

3. To resize the maximum allocated space:

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

- E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB

- You will see a prompt confirming resize done

- You can check the status again using the command discussed in point 1 above

4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:

- Do actions as per point 3 to set the max-size t, say, 1GB

- If you check now, most likely you’ll see that used space is now 0KB

- Do the resize again and set it back to what it was before

- Check your disk space availability in Windows Explorer, you should see the reclaim is done!

Hope this helps.

Please run the following command to find if you have any primary server already for that RG name (IsPrimary=Yes)

Dfsradmin Membership List /RGname:<replication group name> /attr:MemName,RFName,IsPrimary

If the result shows the value for IsPramary attribute is “No”, that means you don’t have any primary server. In this situation, you may set the primary server using the following command

Dfsradmin Membership Set /RGName:<replication group name> /RFName:<replicated folder name> /MemName:<computer name of the member you want to set> /IsPrimary:True

EX. dfsradmin membership set /RGname:contoso.com\namespace\testfolder /RFName:testfolder /memname:Win-DFS-1 /isPrimary:True

2. The actual size of the problematic replicated folder is 3.82GB and the configured size for the staging folder is 4G. I would like to suggest that you set the size of the staging folder is 2 times in large of the replicated folder. It is better to be 7.64GB in size.

3. This member is waiting for initial replication for replicated folder <problematic replicated folder> and is not currently participating in replication. Please check <problematic replicated folder> is enabled in the corresponding replication group.

4. Also, to verify that the DFS replication service can work normally, please make sure that the both of the DFS member servers can be resolved the name of each other. Meanwhile, please verify that the “DFS Replication” and “DFS Namespace” services are started on both DFS member servers.

5. This delay can occur because the member is waiting for the DFS Replication service to retrieve replication settings from Active Directory Domain Services. After the member detects that it is part of replication group, the member will begin initial replication.

There are five common causes of the error that can be occurred, please refer to the following Storage team blog to check if it can be helpful for you.

6. Meanwhile, please download the portqry tool and install it on another server. You can use the following command to verify that the required ports are open.

a.  Click Start, click Run, type cmd in the Open box, and then click OK.

b.  Type “portqry -n problem_server -e 135″ (without quotation mark)

1. Click Start
2. In the search field type Regedit and hit Enter
3. Expand the following registry entry: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles.
4. You will see a list of your profiles.
5. Right click on the profile that you want to copy and click Export (Fig.1.).

Fig.1. Exporting Outlook profiles from the Windows Registry Editor.

6. Then, you can specify the name of the registry file and the location to save it e.g. Desktop.
7. Now, you need to copy the file to another computer and double click it there.
8. Confirm that you want to make changes to the registry.
9. After you run your Outlook, the new profile will be opened (if you have only one) or you will be prompted to choose one of profiles (if you have more than one).

My computer recently blue-screened and rebooted, but is not presenting me with the ’0xc0000428 Windows cannot verify the digital signature for this file’ boot error.

Solutions: Start the computer hit F8 to go to boot menu, select Disable Digital Signature. Windows will start fine, that worked for our Windows Server 2008 R2 running Exchange server.

 In the Command Prompt window, Paste the following command.

 REGSVR32 %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL

 Press ENTER.

 You should see a popup that says the command succeeded.

 Exit the command prompt and try Windows Update again.

Solution below sorted my problem:

Open a CMD prompt in %windir%\system32\wbem

type mofcomp dfsrprovs.mof as below

C:\Windows\System32\wbem> mofcomp dfsrprovs.mof
net stop winmgmt
net start winmgmt
net start iphlpsvc
net stop dfsr
net start dfsr
