Exchange 2010 with Legacy 2000 AD information

I had an interesting issue. I had an old Windows 2000 SBS server on my clients network. Been there for a long time as they needed to use the legacy application that it runs. Most services were disabled (ISA, Exchange). Problem arose as it had been disconnected from the domain for some time. This proved interesting when I tried to remove it from the domain. We had to do a adprep /forceremoval (undocumented).

Anyway, the next issue arose when the new Exchange 2010 server was being installed. We could not create mailboxes for exiting users. What gives? I thought Exchange was not being used on the old server? Seems it was, at one stage.

Ok, time to remove this.

[PS] C:Windowssystem32>get-mailbox LegacyUser

Name                      Alias                ServerName       ProhibitSendQuota
—-                           —–                ———-       —————–
Legacy User        LegacyUser           OldSBS2000       unlimited

Ok, the user still seems to be there. I managed to find a command which disables the mailbox AND removes the legacy information from Active Directory.

[PS] C:Windowssystem32>disable-mailbox LegacyUser

Confirm
Are you sure you want to perform this action?
Disabling Mailbox “LegacyUser” will remove the Exchange properties from the Windows user object and mark the mailbox in
the database for removal.
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Help (default is “Y”):

If you don’t disable the user, you will get the following error:

[PS] C:Windowssystem32>remove-mailbox LegacyUser

Confirm
Are you sure you want to perform this action?
Removing the Mailbox “adeleg” will remove the Active Directory user object and mark the mailbox in the database for removal.
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Help (default is “Y”):
Active Directory operation failed on LegacySBS2000.domain.local. This error is not retriable. Additional information: Acc
ess is denied.
Active directory response: 00000005: SecErr: DSID-03151D12, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
+ CategoryInfo          : NotSpecified: (0:Int32) [Remove-Mailbox], ADOperationException
+ FullyQualifiedErrorId : 103F99DF,Microsoft.Exchange.Management.RecipientTasks.RemoveMailbox

Now you can add mailboxes to these users.You can also remove this information from AD using ADSI Edit, but I STRONGLY DO NOT RECOMMEND THIS. It does work however 😉

I hope this helps someone out there.

Outlook cached mode can cause problems…

Have you had the problem where Outlook sits there, forever, waiting to “update current folder”. I recently had this problem when changing an Outlook 2007 client to HTTP over RPC. After I made this change, weird stuff started to happen. No problem I thought. I will use scanpst.exe and attempt to scan the file. In the past, this has been where most of these sorts of problems lie. This was quite a large file, 3.5gb. After this had completed and still didn’t work, I started scratching my head a bit. What would cause this to happen?

After a bit of testing, I found that turning cached mode off let the folder update. I then proceeded to delete every file out of the Outlook folder (under local settingsapplication datamicrosoftoutlook) apart from the ost file and archive folders.

This fixed the problem. This is the first time I’ve come across this so I thought I’d share.

Google brings Chrome’s renderer to IE with browser plugin

Google plans to drag Internet Explorer into the world of modern Web browsing with a new open source plugin that will inject Chrome’s renderer and JavaScript engine into Microsoft’s browser.

Who would have thought? Hopefully this takes off.

Microsoft Server 2008 Foundation

Microsoft Foundation Server 2008

Microsoft have released a new operating system designed for the small business. Wait, don’t we already have one of those?

Microsoft Server 2008 Foundation is aimed at businesses with 15 employees or less. It’s an OEM product that only comes with new machines sold by either Dell or HP (at time of writing). Another thing to note are the artificial limitations placed on the OS.

  • 15 users maximum
  • Limited to 8gb of memory
  • Visualization disabled

At the same time it does have one benefit. It’s a very cheap Terminal Server.

The OS is upgradable to other versions of server 2008, but what is the point? I can guarentee that by the time this happens, the hardware will be out of date, or the hardware simply won’t be able to be upgraded significantly to improve the performance of the server with the upgraded operating system.

The biggest problem with Foundation is its lack of Exchange. What business operates without email these days?

I love Microsoft products, but this sounds like a knee jerk reaction to a slow uptake on Windows 2008 Small Business Server and will ultimately fail. Watch this space…

Lets just hope this is an April Fools joke.

Windows 7 maye be free…

In a statement to Betanews this afternoon, a Microsoft spokesperson refrained from explicitly denying that it would offer Windows 7 as a free upgrade to some Vista owners.

“Microsoft often explores options with our partners to determine product offerings,” the Microsoft spokesperson told Betanews. “We are not announcing anything new at this time.”

It would certianly be a good move since I’d expect the adoption of Windows 7 will be very slow.

Windows 7 Beta Test Drive (build 7000)

Windows 7 is the newest operating system due out from Microsoft. Microsoft stated in 2007 they were planning Windows 7 development for a three-year time frame starting after the release of its predecessor, Windows Vista. Microsoft has stated that the final release date would be determined by product quality.

We decided to take Windows 7 for a test drive. There was a lot of fuss when Windows Vista was first released. First there were reports on how much slower it was than XP, then we had all the bugs that went with it. Finally Microsoft released Service Pack 1 and things seem to be a lot smoother for the troubled operating system. It is reported now that Windows Vista is finally being adopted by companies around the world. We wondered if Windows 7 will be any different.

We fired up our test box, a Quad Core AMD processor 9550, 4GB memory and 500GB Hard Drive.

First things first, lets install this puppy.

Error installing .Net v3.5 SP1

Many users have reported that they are having problems installing .net 3.5 SP1 or .net 3.0. There are many issues that can cause this problem. After much testing we have found the best way to fix this problem is to run the .net cleanup tool and install .net 3.5 SP1 once it has finished. We recommend removing all .Net versions on your system unless you specifically need one.

[Update: This can also be caused by IIS being installed. If you do not require IIS, uninstall it then try installing the .Net 3.5 SP1 framework again]
