A network shared RemoteApp won’t start on the remote computer

When starting a windows 2008 (R2) RemoteApp from or depends on a network mapped drive you get the error “The program did not start on the remote computer.”

Solution: The problem is caused because the program is hosted on or depends on a network mapped drive. When starting a RemoteApp the program doesn’t wait till the logon script script is finished but just start the program directly and cannot find the right drive or program.
Workarround is to map the network drive persistant so it’s available before the RemoteApp program starts or create a batch file as RemoteApp so you can first map the network drive and then start the program.

Logon issues Windows 2008 R2 Remote Desktop Services

Problem 1: When logging on to a Windows 2008 R2 Remote Desktop Services (former known as Terminal Services) you get the a balloon messages saying a temporary profile is loaded. Changes to the profile are not saved by exiting.

Solution: Backup all data in “%SystemDrive%\Users\UserName” or just rename the folder with .bak at the end. (if this is the first time you try to logon with this account there will be no folder with this username.)
Then start the registry editor and browse to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ ProfileList here you will find all user SID’s logged on to this RDS server. You will find here a subkey know as SID.bak take a look probably this will be the key of the user you get this error.
Delete this key and close registry editor (If you are not sure, first make a backup/export of the key before deleteing is). Then logoff and logon again.

Problem 2: When you try to logon to a Windows 2008 R2 Remote Desktop Services (former known as Terminal Services) server, you get the error: “The Group Policy Client service failed the logon.” “Access is denied.” and you are automatically logged off.

Solution: In my case this problem was caused by a corrupted NTUSER.Dat file. I solved it by logging on as a Administrator changed the user profile to local via Control Panel\User Accounts\User Accounts Configure advanced user profile properties. Then I replaced the NTUSER.Dat from the user by the NTUSER.Dat from the temp profile.
Probably this is caused by using a Terminal Server profile that is corrupted. Another Solution could be deleting this profile and building a new profiles for this user.

Logon Failure on database while accessing or moving mailboxes

We were migrating a SBS 2003 server to a new SBS 2008 server via the swing migration method. After turning on the SBS 2008 server and temporary dc / exchange 2003 server we were not able to access or move the exchange 2003 mailboxes.

The mailbox move gives a: “The move-mailbox task for mailbox ‘mailboxname’ failed. Error: Failed to open mailbox with error: The operation failed.” error on the SBS 2008 (Exchange 2007) server.

On the Exchange 2003 server we get a: Event id 1022: “Logon Failure on database “First Storage Group\Mailbox Store” – Windows account domain\accountname; mailbox /o=domain/ou=first administrative group/cn=Recipients/cn=accountname.Error: 1144″ error.

Solution: It looks like that after forklift and update a exchange 2003 database it could take some time to connect because AD has to replicate the information between the 2 domain controllers. When this is done everything works fine. This can also occur after moving the exchange mailboxes to a the new sbs 2008 / exchange 2007 server.

Server won’t start after a acronis tib file recovery to Hyper-V

Acronis Backup and Recovery 10 is a great tool to create images of disks, volumes or files. You can make images when windows is running and restore then easy with a bootable media to physical hardware. When using Acronis Backup and Recovery 10 Advanced Server Virtual Edition you can recover directly to a Hyper-V or other virtual machine.

To recover a image to a Hyper-V virtual machine you need to start the acronis software and choose for recover point to the image files, choose what to recover, volumes or disk.

Then choose recover to: a new virtual machine (when installed on a machine with Hyper-V role installed it automatically chooses Hyper-V as vm type)

Now you have to set the virtual machine settings. When you use Hyper-V as virtual machine type here is where to take a good look. Because Hyper-V virtual machines can only boot from a IDE hard disk type, if you choose SCSI your virtual machine wont start!

Set all further options just as you wish and you are ready to create the virtual machine. Only thing to do after the image is recoverd to Hyper-V is to attach a network card when needed.

Another possibillity when your server doesn’t start after a recovery this works for physical and virtual machines is to use the universal restore option. Create a bootable media of acronis with the universal restore option and boot from this media. During the options you can choose to use universal restore. With universal restore you are able to restore a image on a different piece of hardware because it detects what hardware is used and updates the Hal. After that you even have the option to install or update disk, raid controller drivers, so your operating system can boot with the right drivers of your new hardware.

Default gateway disappears after restarting SBS 2008 server

Everytime you restart a Small Business Server 2008 the default gateway disappears.

Solution: When you take a look at the following registry key: HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces/ CLSID of the network card this is happening for, you’ll probably notice it by viewing the ipaddress value. Then open the “DefaultGateway” value. In our case you see the default gateway but above it there is an empty line. After removing the empty line, restarting works fine and the problem didn’t occur anymore.

Additonal information can be found on the official SBS blog
