I'm in the process of migrating one of my domains from my SBS2011 to Exchange online plan 2. I made the changes to the DNS, MX records and disabled the SBS exchange mailboxes for the users involved and all seemed ok.

I setup two of the three users and I could receive and send email, though not from the rest of the SBS users, which I believe was an issue with the Global Distribution list not getting updated.

The main problem, which caused me to revert back to the SBS, is that one of the users had a free Microsoft account with the same email as the one that I was using for Exchange Online. This caused the email to be delivered to that account and not the correct one, as well as him not being able to see the other users of the Exchange online.

I changed the primary login of the free account but I couldn't get the account to work in Outlook and the webmail couldn't load either. Please see all my steps below and tell me if I am missing something. I already wasted a day on this simple process.

1) export emails from current SBS account
2) validate domain on Exchange online and make as primary
3) disable mailboxes on SBS so as to not have any conflicts
4) force update of Global distribution list (How?)
5) setup new accounts in new Outlook profiles and mobile devices
6) ensure internal and external mail flow

Can you think of anything that needs to be changed in the process above or can you elaborate with more details on certain steps?

Got a 2008 SBS (yeah, I know...), that C Drive is just about full. according to Tree Size, it’s mostly sharepoint stuff (as shown in attached pic) & users aren’t even using any sharepoint services. didn’t know if I could just delete files, have to do it from a command line or anything like that, or will I need to disable any services?

I'm trying to migrate from SBS 2011 Essentials to Server 2019. I have installed the AD and DNS roles on the new server, promoted it to a DC, configured DNS, and moved the FSMO roles, but when I try to decommission the SBS 2011 using DCPromo (or DCPromo /ForceRemoval), I get the attached error message:
"Failed to detect if Active Directory Domain Services binaries were installed. The error was: Access is denied."

I have tried both our normal domain admin account, as well as the default domain Administrator account with the same result. Both accounts belong to the Domain Admin/Enterprise Admin groups. Our initial research also indicated the account needed to have "Enable computer and user accounts to be trusted for delegation" permission in GPO - I do believe both accounts have this permission.

Everything else I have researched points to a potential issue with DNS and/or DFS replication. DFS replication tests seem to pass successfully and indicate no errors. The DNS events do indicate potential DNS/AD replication errors, but that's kind of where things go over my head and I'm not sure what else to look for or try.

I have attached the output from DCDiag /v command.

Any advice would be appreciated!
SBS 2008, WSUS/SUSDB folder has grown to over 100 GB. The server cleanup wizard aborts. Tried cleaning up one item at a time - still aborts. Deleted all files from the WSUS Content folder - SUSDB still over 100 GB.
(Obviously, system has not been maintained - I was asked to help resolve this issue)
Any suggestions?
Trying to migrate a Exchange 2007 on SBS 2008 to Office 365 but the RPC over HTTP is broken.  

Keep getting the following error in the HTTPerr logs.

HTTP/1.1 RPC_IN_DATA /rpc/rpcproxy.dll 503 3 AppOffline SBS+Web+Applications+application+pool
When testing  on the website . We get the following error.

Not looking to export all the .pst files and have to import.
The server boot up"System recovery options".
Turn off and on, keep back to this screen.

Tried to find some solutions such as boot from Windows CD, startup repair, Command use bootrec , fixboot . Still doesn't work.

Haven't got system image backup. I can see C drive healthy. All data is good.

It was installed EFI system and GPT partition. I can see partition 1 FAT32 100MB ( EFI folder) , partition 2 128MB Reserved  , partition 3 C drive windows system.

Any solution can help without reinstall windows?

If not, I need to put a new hard drive to install windows server. And how can I transfer old hard drive data to new one?  This current server is only use Exchange 2010 server no any files and printer sharing. Just all users and email only.

Thanks ! Top urgent.
We have a single Microsoft Small Business Server 2011 running exchange.

We have been running for some time without problem. We have recently had several clients that are receiving an NDR stating that the account is unknown.

We noticed that the mail never arrives at our mail server, and that the NDR was issued from a google name server.

On checking our MX records, we see :-

mx records via

We can see that the correct MX record is shown as our preferred MX record, and we can see several google MX records with higher preferences.

We are currently unaware of where the google MX records have come from. We did have someone develop our website, who may have added these, but currently unsure as to why.

Will these affect our main MX record as it seems that some of our clients are hitting the google mx rather than our correct mx.

Should there be so many MX records, and do you think this is the root of our problem?

Any advice much appreciated.
I am trying to get my email server to send direct instead of send connectors.

I can send some emails but some are being blocked. I want to know what dns records i need to add at the domain level to make sure they dont get blocked as spam.

Exchange 2016 running as a hosted solution so multiple tennents from different domains
Right now all our clients are using SBS2011 and they use folder redirection for their documents.
We are Migrating them to Server 2016 Running Hyper-V with 3 Guests. One of them being the File Server.

What is the easiest way to change the folder redirection to point to the new file server?
Also , What would be the proper procedure to Bring the data over?
Do I delete the SBS group policy for folder redirection and bring all the Documents back to the local PC's then create a new group Policy on the New Domain controller to redirect to the new File Server.

Or do I just use Robocopy to migrate the redirected folders and create the Group Policy to point to the New Directory?
VM with two VHDX filesHi,
 I have a virtual machine in hyper-v 2016 server. Its OS is SBS2011 with two separate VHDX files. First VHDX contains OS and Active Ddirectory/DHCP/DNS & Exchange (no longer being used due to migration to online exchange) and second VHDX file contains user files, folders and exchange database files (which have been removed since migration to online exchange, but have not uninstalled Exchange software from SBS yet).
 The plan is to move 2nd VHDX file from SBS VM and attach it to a Windows Server 2016 VM.
 As seen in the screenshot, this SBS2011 VM has 1st vhdx file under IDE Controller 0/Hard Drive and 2nd vhdx under SCSI Controller/Hard Drive.
 As I remove 2nd vhdx from this VM and attach it to W2016 VM, what should I keep in mind?
 I know I have to create the same shares in W2016 VM  so that users can access files and folders from the new server.
 I have to change login script so that mapped drives letters are pointing to new server.
 Other than that, what should I be concerned about?

SBS 2011 Migration to Server 2012 R2.
I am planning to migrate from SBS 2011 to Server 2012 R2.
Is there a step by step list to follow
We have Small Business Server 2011 standard.  I have moved all users to Office 365. my intent is to retire SBS 2011.   I am trying to stop folder redirection for a group of users at a time (desktop, documents, pictures, etc.) and utilize OneDrive for Business for all folder redirection.  I am testing this out on a few users to start with.  I was able to stop folder redirection on one account, but I am struggling with others.   I have used the SBS console to uncheck the folder redirection option to the server and I have also verified in group policy management that the users I selected are removed from the SBS folder redirection security group. I have also Disabled the Distributed Link Tracking Client service on the client machine.  I did a gpupdate /force on both client and server.  Rebooted client 3 times and I still have the issue with desktop redirection taking place on these clients.  Any thoughts/ideas on how to kill this?  OneDrive will not allow me to backup until folder redirection is stopped.
SBS MSExchange Autodiscover Unhandled Exception "The Exchange Topology service on server localhost did not return a suitable domain controller."
How do you do that?
We are managing a small (eight-machine) Windows Server *Essentials* 2012 R2 network (single server).  As you may know, one of the features added by the Essentials version of Server 20102 R2 is automatic backup of all client workstations on the network.  In this case, seven of the eight machines back up perfectly.  For some reason, one particular workstation fails to back up every time.  This happens whether the backup is initiated automatically (by schedule) or manually.  This machine had years of flawless back-up operation.  The last good backup was on April 24th.  The next attempted backup was on May 15th, but it (and all other attempts since then) failed completely.

One thing I tried to do was to look through the other end of the telescope and initiate and monitor the backup from the workstation rather than the server.  This can be done in Essentials via the workstation Launchpad program.  This didn't work either, but I did get a more specific error message, which I have attached to this post.  Workstation BackUp Error Message.

The screen image file indicates that something intervened (or failed) between the server and the workstation that stopped the backup process from occurring.  I am able to connect to the server without any problem (e.g., mapped drives, running programs from the server via workstation desktop icons, the workstation is properly identified in the server Essentials Dashboard program, etc.).  There is one other odd thing I noticed in looking this process over,…

Users on Windows 10 PCs are not seeing all search results when searching through network shares that are stored on a file server with Windows Server SBS 2011.  Windows Search service is installed and we've re-indexed the server multiple times.  The only potential solution we've found is to restart the Windows Search service every night but even then it does not seem to help.
Hi guys,

 Like an earlier post I was updating my ssl certificate on my exchange 2007 box on an sbs 2008 box

 After I did this I found that I couldn't access outlook web access and received a 404 error

 my c:\inetpub\wwwroot\owa folder is missing

 I re-ran the Fix my Network Wizard and it fixed some port issues on my router (??) and also came back with 'Certificate Authority is not Installed'....but I'm sure it is installed although its now done this twice. And I still have the /OWA issue.

Anyone any ideas on this?

Hi Everyone,

I am migrating a customer to Office 365 from his old 2003 Exchange server on a SBS 2003

There is one email box that is 35GB, will the Mailbox Export to PST so I can then import into O365

I know its big but the customer wants to keep it for history lookups

I have tried a couple of times and it has bombed out but not sure if was an exhange issue or others we are having.

I have done all the other mailboxes no drama as they where only 7GB or so

Thanks in Advance

I have installed Windows SBS 2008 standard on an old server. Is there somewhere to download the service packs and updates?
I just use it to play with in my private lab. But it would be nice to have the updates and service packs.
Thankful for any help.
We've been having problems with an SBS 2011 server recently.  People weren't getting the logon script to get the mapped drives, and if they tried to get to shares, they were prompted to login again (it's a domain).  Then they get the shares

After some troubleshooting, it was because NetLogon wasn't started.  We can manually start netlogon (which is set to automatic) and everything is fine... till a reboot and netlogon doesn't start.

Looking around for info on that issue, it talks of making sure it's set as a dependancy to Lanman server and lanman workstation.  and to make sure those are set to automatic.

Uh, I don't see those listed in services at all!

And running dcdiag for the netlogon issue, also pointed ot windows time service not started / the server not advertising as a valid time server.

Any thoughts on, most pressing - getting netlogon to start (and should lanman server and lanman workstation be in the list of services in computer management?

and maybe something to get me started with windows time?

I saw a batch script to help resolve that:

net stop w32time
 w32tm /unregister
 w32tm /register
 net start w32time

but now, after a reboot, I manually start netlogon successfully.  Then look and windows time is not in the server list.  

if I run w32tm /register, I get  windows time in the services list.  I change login from local account to local system account.  Then start it manually, I get error 1709 account specified for the service is …
I'm trying to convince a client that has SBS2011 to finally move to O365. I'm recommending that he purchases Exchange Online Plan 2.

Currently the SBS handles email from three domains (, and Will Exchange Online handle this as well?

Hopefully we will start with one of the companies, as a test, since there are only 3-5 email addresses for that one.

What is the correct procedure to do this from the SBS, while keeping my AD synced with the O365 and everything?
can we upgrade RAM in SBS 2011 running server from 16GB to 32GB, would it accept the change over or give problem?
I inherited a network with a Windows SBS2008 Server, 2016 Essentials server, and a 2012 Essentials server.  We want to remove the SBS2008 server and its hardware from the domain.  Attempted to remove using this guide:  Moved all FSMO roles, and DHCP to other servers, however,  when turning off and shutting down the SBS2008, the Active Directory and DHCP stops working.  Obviously, there's something the SBS2008 provides that keeps AD and DHCP working.   Spent a lot of time on this already and haven't been able to resolve.   On solution I'm thinking of is to virtualize (P2V) the SBS2008 and activate HyperV on one of the other servers and move it there, so, we can get rid of the hardware.   Want to know if anyone has done this, and what are the pros and cons.
