I recently needed to configure a Cisco 837 to use bridge mode for my home ADSL. After a bit of troubleshooting I managed to get the correct config.
Then just make sure that your interfaces are not shutdown and you should be able to dial PPPoE with your WAN router from behind the 837.

I was recently doing an upgrade from Vcentre 4.1 to 5.5 and the Vcentre install kept failling with the following error: Error 1935 An error occurred during the installation of assembly component HRESULT: 0x80070422
To resolve it all you have to do is to make sure the Windows Modules Installer service is enabled and started.
If it happens after this again check the HRESULT number it will have changed.
I recently had a requirement to run 2 IP addresses on the same nic on a server 2008R2. The problem was that only 1 IP address was routable over the MPLS and the second IP address kept registering itself in DNS.
To resolve the issue I found the following command:
Netsh int ipv4 add address “Local Area Connection” <IP Address> <Netmask> skipassource=true
Just remember to not add the secondary IP address via Network and Sharing center.
– 3x Server 2012 R2 servers (Can be virtual machines)
1. Access Edge Server
2. Front End Server
3. Office Web App Server
– 4x Public IP’s
– Unified communication public certificate (4 names)
The Office Web App server is required to properly share PowerPoint presentation.
For PABX integration you would require another server that will be the mediation server. You would also need a SIP device (Usually provided by PABX company but has to be Lync capable)
- Get Office 365 admin login details (Will be emailed to you when you buy Office 365 online or from 3rd party supplier that will purchase Office 365 on your behalf)
- Login and ensure that the required amount of licenses is active – Get these activated well in advance
- Add email domain
- You would need to create a TXT record for the domain to verify that you own the domain. Only once this is done can you add the domain on Office 365 (Make sure you do this well in advance)
- Get a populated user list with the following information for Office 365 user creation (Template can be downloaded from Office 365 portal)
- User Name (Email address)
- First Name
- Last Name
- Display Name
- Import user list to Office 365 (Create bulk users)
- Get a populated user list for user creation in Migrationwiz and required credentials for migration
- Source Email
- Source Login Name (For Exchange you can setup an account with impersonation and delegation rights and then specify this account for all the login names)
- Source Password (For Exchange you can setup an account with impersonation and delegation rights and then specify this account for all the passwords – Don’t need to get individual passwords)
- Destination Email (Will only be different from source if moving to new email domain)
- Destination Login Name (Use the admin account for Office 365)
- Destination Password (Use the admin account for Office 365)
- Get OWA address for source server (If using Exchange)
- Create migrationwiz project and specify source and destination details
- Import user list to Migrationwiz
- Download and install the sign in assistance and the windows azure PowerShell module for Office 365
- Open Azure PowerShell and run the following commands (This give the specified account full rights to all the mailboxes on Office 365 which is required for migrationwiz. Should only be done after all Office 365 users have been created):
$cred = Get-Credential
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $cred -Authentication Basic -AllowRedirection
Get-Mailbox -ResultSize Unlimited | Add-MailboxPermission -AccessRights FullAccess -Automapping $false -User ‘YouOffice365AdminUser’
- Create admin account for migrationwiz on source server and assign impersonation or delegation rights to account (Exchange only)
- Preferably use impersonation as this will use the users actual account and you won’t be limited on the amount of concurrent connections to Office 365
- If using delegation it will use the admin account for the migrations and account will be limited on the number of concurrent connections to Office 365 (E.g. Limited to 4 or 5 migration that can run at a time)
- This account needs to be specified as the Source login name and password for the document that you will import to migrationwiz
- It is recommended to set up both Impersonation and delegation so that you can fall back on the other if one fails
- Run the following command to setup impersonation:
New-ManagementRoleAssignment -Role ApplicationImpersonation -User ‘useraccount’
- Run the following commang to setup delegation:
Get-mailbox | add-MailboxPermission -user ‘useraccount‘ -AccessRights fullaccess -InheritanceType all
- Run migration of mails only (No calendar, tasks, notes or contacts as this changes on a daily basis – It will create duplicates if users make changes to items that has been migrated and we run migration again)
- Migrate only mails that are older than a month (Newer mails will only be migrated with switchover – If you migrate all mails and user make change it will also create duplicates)
- This needs to be done well in advance as this might take a while to complete depending on size of mailboxes and line speed
- This will cause a lot of traffic on the line so communicate this to the client
- 1-2 days before switchover run migration for mails later than two weeks
- Change MX and autodiscover record to Office 365
- Run migration wiz for all mails and this time include all items (Calendar, contacts, notes and tasks)
- Two days after switchover run migration wiz again (MX records will take time to propagate so some mails might have been sent to old mail server)
Received below error as there was not enough free space on current (Default) scratch area space (Area to wright temp file to – required for host updates)
- Need to change scratch location to area that have sufficient free space
- Create a new folder on datastore for each host using the following naming convention: ‘.locker-hostname’
- Put host in maintenance mode
- Change scratch area for hosts to new folder location (Configuration > Advanced settings > ScratchConfig)
- You would have to use the location name for the datastore (E.g. ‘/vmfs/volumes/5267c981-9a88a078-f998-90b11c592c9a/.locker-hostname’)
- Reboot host
- Exit maintenance mode
Recently had a problem with a Powershell script that was configured via Group to deploy at start up.
The problem I had was that no matter what the script would never run. Doing a GPResult /z it would show me the script is being applied but with the following message:
Last Executed: This script has not yet been executed.
After much searching and testing I found that the script would run if I removed the spaces in the script name.
I know its a simple mistake but the server did not tell me that it could not find the file.
When backing up SQL databases you might get the following error message.
V-79-57344-65085 - There was a problem running the DBCC.
DBCC results for “Database”
To resolve the error take the following steps.
1. Connect to SQL Management Studio
2. Run manual SQL backups on the Database in question
3. Right click Database and select “new query”
4. Type the below commands exactly as is. It will only scan the Database and report what is wrong with it.
5. In my case it was a table miss match and the report said I should run DBCC UPDATEUSAGE
6. I created a new query with the following details:
DBCC UPDATEUSAGE (0);
After this my Backups completed successfully again.
I was getting this error when trying to install an image.
It turned out in disk configuration I assigned the number 1 to the first disk. Changing it to Disk 0 solved the problem.
I found the interesting post on how to configure your computer to serve as a wireless access point.
1. Open command prompt as administrator
2. netsh wlan show drivers Look for Wifi driver – find ‘Hosted network supported’ – if Yes, then OK
3. netsh wlan set hostednetwork mode=allow ssid=your_chosen_ssidkey=8_or_more_character_key
4. netsh wlan start hostednetwork
5. Go to network and sharing center –> Change adapter settings. Right click your internet connected adapter and go to properties. Click the sharing tab. Check the ‘allow other network users to connect through this computer’s internet connection.
Create a shortcut to the command in step 4 preceeded by ‘cmd.exe /c ‘ and stick on the desktop or wherever to make it easier to start the hotspot after rebooting. Remember to change the shortcut properties (advanced) to run as administrator. To stop the hotspot, replace start in step 4 with stop.
